25:22
About 7pm. (Uh) I left my house to go to the grocery
stores, buy my groceries for the week. [Examiner: What grocery store?] Target.
And (pause) I was leaving my neighbourhood when I saw this guy (um) walking
slowly in front of a house, looking towards the house. (Um) And I knew that he
didn’t belong there so it made me a little suspiscious and then he kept staring
around him (er) at me, and behind and it arose my suspicion and then he, and it
was raining and he didn’t look like he was in a rush to get out of the rain, he
don’t look like he was (aaah) hardcore, physical, like exercising and he was
you know running in the rain, he just looked out of place from what they tell
us in (eh) the neighbourhood watch. Sooo (sigh) I drove passed him and I went
to the club-house and I called the non-emergency line. (Um) And as I was on the
phone with the non-emergency line, he walked passed my car and I lost visual
contact of him. (Um) The operator asked if I could get to somewhere where I can
see or at least give him a direction of where he was headed. I said “yes” and I
pulled out and I drove adjacent to the clubhouse. (Sigh) And I was unfamiliar
with the street name. The operator asked me what street I was on and it’s not
the street that I live on, it’s a side-street that cuts through the
neighbourhood and I told him I didn’t know and they said “we need to know” and
and when we were at the clubhouse I gave them the clubhouse address and they
are like “we need to know what house you are in front of” and I said “listen,
if you come to the clubhouse and go straight, left and then you will see me
there. (Uh) At that this point the guy walked around my car en (and) he had his
hand in his waistband and I didn’t hear if he said anything, my windows were up
and it was raining and I was on the phone with (em) the non-emergency
dispatcher and then he disappeared back through a cut route between the houses.
(Aaah) While he was doing that, the operator asked me. They said “we need to
know what exact address you’re at”. And I all the houses I was next to at the
back of the house and they are town houses so I didn’t know the address. And
they said “we need to know what street you are on or what address you’re at”. I
think I in the heat of the moment might have given them my street address and
then they said “is that your home address or your where you are at now?” (Er)
And that’s my home address and I got out of my car to look for a street sign so
that I could at least tell them what street I was on [why would he get out of
his car, in the rain, to look for a street sign???]. And (pause) there was no
street sign and I couldn’t make out the house in front of me because there was
a big pickup truck there so I knew if I, I saw him walk through the cut-road
and then make a right behind other houses. I knew if I went straight and I
didn’t cut through to where he went, that was the street I lived on Retreat
View Circle and I knew if I got to that street I could tell them the exact
house number and street that I was at. So as I walked through, I looked to my
right where he had gone through (er) the operator said “are you following
him?”. And I said “yes”. They said we don’t need you to do that. I said “ok” and I walked through to the other
end of the street to give them the address and I was doing that and I said
“he’s not here anymore, he’s gone”. And they said “you don’t see him?” and I
said “no, he’s gone”. And they said do you still want us…” and by this time I
had gone into Retreat View Circle (sniff) and they said “do you still want us
to send a police officer out?”. And I said “yes”. And they said “well, where do
you want the officer to meet you at?” And I said “just tell them to go to the
club house make a left” and I gave them a description of my car and I said “I’ll
meet them back at my car”. (Sigh) So I walked through again and as I was about
half-way through (aar) he appeared out of nowhere. {E: and he saw the phone?}.
No, I hung up, and they said “we have an officer en route” and I said “ok thanks” after he asked me if I wanted an
officer there. And they said we have an officer en route and I told them to
meet me at my car and I hung up. (Deep breathe in) And I put my phone away
(deep breathe out). And (pause) when I got half way to my car
from the street. Again behind the houses en (and) a dark area, I heard him say
“you got a problem?!” and I turned around and I saw him and I and I went to [stutter:
en-n 30:44] go for my phone [makes
the movement for reaching a gun at the hip] and [not sure what he said: shhhhta]
and call 911 instead of non-emergency this time. (Sigh) But I (e-e-e) guess I
didn’t have my phone in the pocket I thought I had it in, I had it in my jocket
pocket, and I reached my pocket and I was looking for my phone (sigh) and he
just punched me in the nose (sigh). And I fell backwards into the side somehow
ended up on my back (sigh) he ended up on top of me and he kept on punching my
face and my head. I was screaming for help and he told me “shut the fuck up”. I
kept yelling for help and I got a little bit of leverage and I started to sit
up and then he took my head and slammed it into the concrete (sigh) several
times and each time it felt like my head was going to explode more than the
last. (Sigh) I felt like I was going to lose consciousness (er) and I sss and
then I really, I started screaming for help and he covered my nose with one
hand and my mouth with the other one (sigh) and he told me “shut the fuck up”
and (er) I couldn’t breathe. I was suffocating (pause) and (pause) all I could
think about was I didn’t want him to keep slamming my head on the concrete so I
kinda shifted, squirmed my way out, not out from under him but like to
where…cause the concrete was only, it was a sidewalk en (and) it felt like he
only had my head on maybe a quarter of the concrete and I could shift my way
out and get onto the grass which was where he was slamming my head and it would
just hit the grass and not the concrete. (Sigh) When I shifted, my jacket came
up and my shirt came up and it exposed my firearm and that’s when he said, he
like sat up and said “you’re going to die tonight mother fucker” and I felt him
take one hand off my mouth and slide it down my chest…and I just pinched his
arm, I grabbed my gun en (and) I (pause) aimed it at him (pause) and fired one
shot (sigh). He kinda sat back and said “you got me” or you got me” or you got it” or something like
that. And I thought he was saying that he heard the shot and that he was giving
up. So I pushed him off me and. I don’t remember if I pushed him off me err (or) I pushed him back. Either way he I ended up on
top of him, straddling him and he was face down (sniff) and I when he was
hitting me in the face and the head, I felt like he was hitting me with something,
in his hands. So I thought he had a weapon and I grabbed his hands and I pushed
him away from his body and I said “stop!” “just stop! don’t move”. And he was
going to say something like “aah aah” and cursing and I said “stop! don’t
move”. And then somebody came and they had a flashlight and I thought it was a
cop en (and) I said. I still had a gun in my hand as I was holding his hand
out. And I said “are you a cop?” and he said “no” and I said, he said “I’ll call
em” and I said “I don’t need you to call them, I already called them. They are
on their way. I need you to help me…restrain this guy”. And he said like “I’m
calling police I’m already on the phone with them”. (Sigh)I got up, off
of him, cause he stopped struggling. And I thought he had just stopped
struggling…And (Sigh) Then I, I holstered my weapon and I saw another
flashlight and I said “are you the police?” cause I had blood all over my face
and my eyes en...and the flashlight…it was dark where I was, so the flashlight
was really bright and I said “are you the police?” and he said “who shot him?”
And I said “I did”. And I put my hands above my head like that (gesture). And I
don’t remember if he told me to turn my back to him and walk back towards him.
But I turned my back to him and I said “I did”. And I raised my jacket and I
said “my gun’s right there”. And and I think I told him a few times “my gun’s
right there”, “it’s right there”. And he said “I know where it is. Just keep
your hands on your head. Don’t move.” And I said “can you just take my gun?”.
And he said “I’m taking care of it, just don’t move!” So I (er) stopped. He
handcuffed me. He took my hands down and
handcuffed me. OH! That’s when he brought my hands down I said “my gun’s right
there on my right side”. Because I didn’t want him to think that, you know, I
was gonna grab for it or something so. He put my hands behind my back,
handcuffed me and then he took my gun and…(arrrr) I think it was the same
officer that took me to his car annnnd…paramedics got there. They went to check
on him first and then they came over (drink of water)…And poured peroxide on my
head…back of my head…felt my nose. (Um) And they told…I don’t remember if it
was police officer…another EMS guy…they said “his nose is broken and he’s going
to need one probably two stitches on the back of his head”. {E: ah hum}. And
(aah) (long pause). And they said (aah) well we’re gonna take him down for
questioning. (Pause) And (aah) somebody said “should we take him for
questioning or CFR first?” and they said “no, we’ll take him to the station
first”. (Sniff) And (pause) I didn’t realise at the time CFR was Central Florida
Regional, the hospital. (En) I just kinda got into the back of the car and they
brought me here.
{E: Ok. Alright, so is that, were
you on your phone at the time (um) when (er) (er) he was beating you?}. No.
{Ok. So there was no communication between you and the cops at that point in
time?}. No. I’m sorry, there was a guy…I couldn’t really see, like I said, there
was blood in my eyes and I saw somebody looking out through this sliding glass
door. And I said “help me, help me”. I think he said “I’m calling 911”. But the
guy was beating me in the head and face and I-I-I-I but he-e-e might have…{So
was there a possible bystander there?}. Yes. He might have been on the phone
with 911. I don’t know. But I was not communicating with the police at that
time. {Ok. After he disappeared in through the cut-throat, ok, he turned to the
right?}. Yes sir. {At that time you hung up right around that time you hung up
with (ere r) dispatch}. Shortly after that. {Um. Then you were walking there,
you were walking back through, then he disappeared right?}. Yes sir. {The next
thing you know he comes out of nowhere}. Yes sir. {And he says “you’ve got a
problem”} Yes sir. {Or some other thing. Ok. At that point you went for your
phone?}. Yes sir. {And then he punched you in the face}. I I answered him. I
said “no, I don’t have a problem” and that’s when I went for my phone. Then he
punched me in the face. {Then did you guys exchange some punches?}. I didn’t
hit him, at all. I was just trying to defend myself. But every time he punched
me in the nose, it felt like my head was going to explode. {Ok. Was it at that
time that you pulled out your gun?}. No. {Any time prior to that did you pull
out your gun?}. No. {Ok}. {So this possible bystander you told to call 911 or
help, he would be able to tell us that your gun was still in your holster?}.
Yes sir. {Or didn’t see the gun}. Correct. {Ok. Cause if it was in your holster
you probably wouldn’t see it}. No sir. I mean…as we were wrestling I said my
jacket came up. {I understand that. But if he was to look up and look at you,
it wouldn’t be in your hand or anything}. No sir. {Ok}. {And you don’t know
this guy?}. No. {Ok}. {Other than um, wha why did you try to maintain such
close proximity to him?}. To the police where what direction he was heading at.
{Didn’t you feel that you were putting yourself in danger?}. No. Because where
I was parked my headlights were lighting illuminating and I saw him turn down
the…and by the time I was on the phone with the thee non-emergency, by the time
I got to where he was at, I felt he had already made his way (er). I called
non-emergency probably a dozen times, and they these guys are known just to
run. As soon as they get suspicious, they run, and they know the neighbourhood
back and forth and they just disappear between houses, en within seconds. So I
kinda walked and I looked around the corner and he was gone. So I that’s what I
told the non-emergency, “he’s gone”. {What was this guy wearing?}. (Er) Grey
hoodie and I don’t remember if they were grey pants or like stonewashed denim
pants, I think. {Mumbled “denim pants”?} Pardon? {Denim pants?}. Ah no ah ya
like denim but like stonewashed. I think they were light coloured. They might
have been jeans. {And he was a black man?}. Yes sir. {About how tall?}. Ahhh
(um). 5 8 9, 5.11 I’d say. Six foot. {When you were laying on the ground, you
were lying on your back right?}. Yes sir. {Ok. That’s when your jacket came up
and he your gun right?}. Yes sir. {Your gun was on your left-side or your
right-side?}. On my right-side. {Ok. So your guns on your right-side. Where
were your hands at?}. (Er) Trying to keep his hands away. {And then you felt,
what did you feel next?}. His hand slide down my chest. And he took one hand…he
had one hand on my mouth and one hand on my nose. And he took one off. And
that’s when he said “you’re going to die mother fucker”. And I felt his going
down the side of my chest and (sigh) to be honest {interrupted by examiner}.
{So it felt something like this?}. Ja. Brushing. And to be honest with you, the
whole time I forgot that I had the gun and when he said that I was going to die
and I felt him brushing I (er) it automatically clicked that he was going for
my gun. {So your hands right here defending yourself. His hands going down?}.
Yes sir. {Were both your hands on the weapon?}. No sir. {Where were his hands
when you went to retrieve the weapon?}. One hand was going towards the gun. He
took it off my mouth. {Right}. And I was trying to get his hand he was
suffocating me and I was trying to get his hands off my face. So when I felt
his hand, he let go of my mouth so I wasn’t trying to do anything again with my
right hand. So I grabbed my gun. En (and) I don’t know if he did at the same
time or what the case was. But I got to it first. {Ok. And then how did you
come to fire upon him from that position? Because you are laying down like this
ok on your back right?} Yes sir. {And you just bring it out of the holster like
this?}. Yes sir. {Ok. Did you like try to push it into him or anything?}. No
sir. {You just fired it almost like from the hip?}. I think I made sure (pause)
that it wasn’t, cause my hand was in the way and made sure it was passed my
hand cause his other hand was still in my face. So I made sure that… {So you
were that far away where he could punch you?}. No no no. He was like putting
all his weight on my nose and my mouth trying to suffocate me. So he like
creating a crevice with his body. {ahuh}. And then he like slid to go for my
gun (pause). {Then did he go for your gun with his left hand or his right
hand?}. (Sigh) I don’t recall. I don’t recall. Which hand he used. {Ok. One of
the hands went?}. Yes sir. {Ok. And one was on your mouth?}. That that’s when
it clicked that I had my gun and when he said… {The hand that was on your mouth
went to the gun?}. Yes sir. {And then you got it and then you went like this?}.
(Sigh) I think I went far enough to where I could make sure it was passed my
other hand (pause) and (pause) in his general area. {From what you describe to
me, he is not that far away from you}. No. He’s on me. {He’s on top of you?}.
Yes sir. {Right so there’s not a whole lot of distance between you and him}.
Right. {So you can’t really extend your arm}. Correct. {Cause then you’ve got a
gun sticking right out what kind of gun is it?}. Kel-Tec 9mm. {Kel-Tec 9?}. Yes
sir. {So it’s probably only about that long?}. Shorter. {It’s a little tiny
gun}. Yes sir. {But still I mean, I mean, you don’t have hardly any play}. No
sir. {Before that gun is directly into his chest}. Correct. I was (pause) on
him. I knew I was…{As soon as the round went off, you stopped trying to attacking
him?}. Eh yes. He sat back. And said “you got me” or “you got it”, whatever.
{Ok}. (Long pause). {And I’m sure it all happened that quick too}. (Sigh) It
felt like an eternity. {*Phone rings*}. {Sorry about that}. No it’s cool. {Ok.
Um.}. And I thought the police (pause) were there, there were gonna be there.
So it felt like it took forever. {Ye. That part takes forever. I’ve been there
before. Not in the situation you have but you know it seems like it takes
forever for somebody to get there when you want them. When in reality it was
only probably a couple minutes.}
Ends 46:00.
They both step out for a break
before the VSA examination.

Lie Detection Made Easy
One can either sign up for long, expensive training courses or you can read Truth Extraction (Reading between the lies) AND Truth Extraction Contd (How To Analyse Lies and Eyes) by Clifton Coetzee.
This well known truth verification practitioner
has studied several truth verification (lie detection) technologies and techniques (Scan; Micro-Facial Expressions; Facial Analysis and Kinesics)
He has encapsulated the best of the best in a handy manual for anyone who wishes to become a skilled lie-detector.
For more on Voice Stress Analysis ( VSA ) visit the sites: http://www.avsapro.com and http://www.polyvsa.co.za/
Want to know how to beat or fool a manual VSA Examination..?? Ask me how.
But don't try to beat the Examiner. A well trained VSA examiner should never be underestimated. They have the ability to detect your Countermeasure attempts.

AVSA PRO - The VSA Evolution
The VSA Industry has been somewhat stagnant for the past decade. When Jean-Louis Gouin (Alpes-Software) developed Diogenes Lantern for Bill Ames, a new era began.
Sadly, Bill Ames passed away several years ago. Two of his erstwhile employees assumed the rights to continue distributing Diogenes and they employed Alpes-Software to re-label Diogenes as TDT. Alpes retained copyright ownership of the Diogenes program.
TDT (Truth Detection Technologies)- the name is somewhat of a misnomer as they have not produced any technology, despite their bold claims on their website.
In late 2009 I (Clifton Coetzee) made contact with Jean-Louis Gouin and we began a collaboration that has revolutionised the VSA industry.
Before I continue, it is important that one never confuses LVA with traditional VSA.
In my years of patient review of DOD technologies, I have found that LVA has reliability less than chance. Therefore I dismissed it totally in 1998, 200, 2002 and again in 2004. Since 1998 many LVA renditions have come to the marketplace:
Truster; Truster Pro; Tipi; Vipre/Vypre; SVX13; SVX13A; TVSA13;
The only true VSA applications as at current time ( May 2011) are AVSA Pro; CVSA; PSE5128 and TDT (Diogenes)
Interestingly, Diogenes Lantern was the only vsa program to have received a modicum of validity in scientific validation reviews, almost a decade ago.
The good news is, that Jean-Louis Gouin wrote Diogenes and it is the grounding for AVSAPRO. The spectrograph capture window in Diogenes and the general layout will be recognised in AVSAPRO, but that is where all similarity ends.
Where Diogenes (now TDT ) was a manual vsa program, AVSAPRO is fully automated with evolutionary features.
No longer does an examiner have to cut and highlight or tab the required CQ / RQ responses. AVSAPRO is equipped with validated question protocols and auto captures the responses required. Each question in a protocol is rolled onto the screen only when the preceding question has been asked, answered and captured. Questions can be re-asked without affecting the numerical allocation.
AVSAPRO automatically rotates the RQ's in subsequent charts (exams)
AVSAPRO maintains consistent cadence control, which in turn produces consistently reliable results. At the end of every question, the examiner habitually presses the response key, which emits an audible answer cue for the examinee 1,5 seconds later.
As the examinee has already recognised the question approximately 1-1,5 seconds before quesion terminates, the required Onset Delay phase of 2-2,5 seconds has been satisfied.
AVSAPRO is equippped with extremely versatile and unique filing alternatives. Tests can be recorded into any directory on the pc or direct to removable media.
Full recall is available via either of two independent methods.
Tests can be run in auto mode or manual mode. Scoring may be effected manually (examiner) or by the neural network processor.
AVSAPRO auto scoring does not involve random application of unproven theories or electronic recognition of tone or pitch. AVSAPRO has been trained by the neural network according to Expert Human scoring of 000's of voice wavs, blind scored and rescored several times. Many known outcome solutions have been utilised to train the neural network.
It can be said that AVSAPRO is the first DOD technology ever to utilise Artificial Intelligence (AI).
Futue versions of AVSAPRO will make provision for scoring of multiple word utterance to a Dichotomous question. GSR and Cardio functions are to be added.
The future of DOD is AVSAPRO.
Continuing the AVSAPRO evolution. In late 2014, Clifton and Jean-Louis began to develop a ne web based application, AvsaPro Global.
AVSAPRO Global is the Gold Standard for a world standardisation of Voice Screening and Testing.
Global version will be freely downloadable from the internet. Users can choose the type of question template required; either for Pre-Employment Screening; Periodic Honesty Screening, or Felony Issues such as theft or fraud.
Globa; version has a question library to assist users in question selection to match the Issues or Screenings. The questions are colour coded and can only be selected for a matching colour field.
APA validated question constructs are utilised to maintain accuracy.
Cadence(timing) is controlled and the tests are easily run, by following simple instructions in the Facilitators Manual.
Ultimately a simplified report is produced. The tests and screenings are scored by a neural network processor, to deliver a high degree of consistency and reliability.
The human involvement has been further removed in order to demistify and decontaminate tests and results.
While the App is free to download, users must register online and pay a nominal fee to purchase tests (licences) in batches of 1, or 5, or 10, or 50, or 100.
Global version will cater mainly for high volume users who require accuracy and consistency.
However, Accredited Professional Examiners will have access to the Professional section where there is freedom question construction, but template structure is maintained to produce simplified easy to understand reports.
No longer will anyone have to employ expensive specialists and no longer will anyone have to pay exorbitant fees for specialist training.
Reliable Screening and Testing of personnel is about to become very affordable.

Voice Stress Analysis (Wikipedia Excerpt)
PRINCIPLES & ORIGINS
VSA is based on the subsonic components of human voice not audible to observers, now known as the Lippold Tremor. In 1957, Olaf Lippold discovered this physiological tremor in the human voice in the 8-12 Hz range. Lippold, Redfearn and Vuco began exploring the correlation between muscle activity and stress, and found that when the fight or flight response presents in a person, one of the psycho-physiological responses that manifest, is the involuntary tensing of the 'soft' striated muscles, particularly, the laryngeal muscles. Under normal circumstances, the laryngeal muscle is relaxed, producing recorded voice at approximately 12Hz. Under stress however, the tensed laryngeal muscle produces voice significantly lower in pitch.
The original VSA technology was devised by three former US Army personnel. The three, Bell, McQuiston & Ford, developed the PSE 1, an analogue machine. The three, under Dektor Counterintelligence and Security, Inc., manufactured the PSE 1000 and later the PSE 2000. The first supplier of VSA technology was Dektor. Dektor manufactured the PSE 1000, an analogue machine, that was later replaced by the PSE 2000.
The National Institute Of Truth Verification (NITV, West Palm Beach) then produced and marketed a digital application based on the McQuiston-Ford algorithm in April, 1997.f> In the past 10 years VSA has been used primarily in digital applications: Digital Voice Stress Analysis (D-VSA). The primary suppliers are NITV-CVSA; Dektor-PSE5128, Diogenes-Lantern and Baker-FVSA.
The primary use of VSA is in the arena of 'Detection Of Deception'. As with the polygraph, Manual VSA technology is inert and has no artificial intelligence component. It can be said that both technologies are equally reliable in determining a person's truthfulness under similar circumstances. Both technologies record data that they were designed to do. It is the use of that data as a means for lie detection that remains controversial.
Avsapro is an automated VSA system utilising a neural network (Artificial Intelligence) Avsapro renders all other VSA programs to be redundant and obsolete.
Applications
The purpose of a VSA examination is to determine the truthfulness of responses made by an examinee regarding the subject under investigation. Determinations are made by analyzing and scoring the voice-grams produced by the examinee. Traditional analysis of voice grams was achieved by allocating "percentages of stress" ( % ) according to the patterns so produced.
High levels of (deceptive) stress indicate that the examinee is deceptive as is the case with polygraph. In respect of VSA, squared voice grams indicates higher stress, whilst 'wave form' or 'domed' signatures indicate less stress.
Questions may be posed to elicit simple "yes" or "no" answers, but can be posed to produce a narrative response. Questions are formulated for each individual being examined to compare situational stress signatures with Control Question and Relevant Question signatures, in order to identify (deceptive) 'stress signatures'.
VSA technology together with validated testing protocols, is designed to protect the innocent and avoid 'false positive' results. VSA is designed to assist any investigation by establishing the veracity of a subject's verbal responses.
Devices used to analyze voice stress are usually used in the presence of the individual under investigation; however, they can also be used without his or her knowledge. Since all that is needed is a voice, a wireless microphone or a tape recording can provide the necessary input signal.
Traditional VSA utilizes the McQuiston-Ford algorithm and this is the technology developed in the USA for the US Defence Agencies and is used by US Law Enforcement agencies.
There are no known physical countermeasures for VSA. Conversely, the simple use of a 'tack' placed under the tongue of the examinee, to be used as a countermeasure, can reduce the accuracy of polygraph results from 98% to 26%.
Use In law enforcement
A great deal of voice stress testing (VSA) has been conducted. In the United States, most states do not regulate the private use of these devices. However, the CIA and FBI both use VSA at times, in their own investigations. The technology is currently recognized in 43 states.
Many intelligence agencies as well as private forensic psychophysiologists worldwide utilise VSA in preference to polygraph technology.
Methodology and accuracy
The McQuiston-Ford algorithm used for Voice Stress Analysis is reliably accurate. The recorded "micro tremors" in a persons voice are converted via the algorithm into a scorable voice gram. The discrepancy in researched accuracy may result from incorrectly trained or non-trained persons utilizing the technology incorrectly. This is evident by some Polygraphists trying to "test" VSA technology without having received accredited training in the use thereof.
Polygraph-only associations have disputed the accuracy of VSA, although many accredited polygraphists have trained in the use of VSA and use VSA to good effect. The traditional analysis and scoring of voice-grams by means of assigning 'percentages' is time consuming.
In 2002, Clifton Coetzee (Polygraph & VSA Instructor) devised a scoring method for voice grams incorporating the 'UTAH 7 Point' scoring system, as used by modern day polygraphists. Reactive or Responsive patterns are assigned a weighting of +3 to -3.
The use of CQT testing protocols developed by John Reid and Cleve Backster are used for greater reliability of VSA results. It is important that VSA examiners be skilled in the use of enforced, timed pauses between stimulus (question) and response (answer). As in the polygraph situation, the fight or flight response has onset and conclusion delays, which must be considered by examiners to achieve reliable results.
In 2010 Clifton Coetzee and Jean-Louis Gouin developed Avsapro, an automated VSA system that eliminates all common examiner errors. Avsapro built in cadence features provide consistency in scoring that no other VSA system can emulate.

Voice Stress Analysis
Voice Stress Analysis (VSA) is a lie detection technology- and uniquely deployed as such- which is newer than the polygraph, but still controversial.[1]
VSA technology records psychophysiological stress responses that are present in human voice, when a person suffers psychological stress in response to a stimulus (question) and where the consequences of lying may be dire for the subject being 'tested'.[2]
In the Detection Of Deception (DOD) scenario, the voice-stress produced in response to a Relevant Question ("did you do it?") is referred to as psychological stress or 'deceptive stress'. No DOD technology can detect a lies or truth unequivocally. It is the fear of being exposed as lying to the question being posed that produces the 'high stress' voice signature, aka voice graph or voice tracing.
The technique's accuracy remains debated by polygraph-industry initiated research. There are independent research studies that support the use of VSA as a reliable lie detection technology, whilst there are other studies that dispute its reliability.[3][4]
For example, a 2005 study found the TrusterPro LVA system to be invalid for detection of guilty knowledge. Research commissioned by the Department of Justice and conducted by AFRL (Air Force Rome Labs), as well as several other researchers, also suggested less accuracy rates for the same system, marketed in the US under a different name ("Vericator").
The skill and experience of the VSA Examiner is of utmost importance.[5]
LVA - Layered Voice Analysis technology- known as LVA or VRA - is finding use as a screening tool in the UK, in which recipients of jobless benefits are faced with the 'threat only' of a test, and would consequently face more scrutiny if they "failed".
The LVA test itself has accuracy levels less than chance (50%) but the mere threat is used in this instance. [6]
LVA trials conducted by private Polygraph & VSA Instructor/Examiners in South Africa produced reliability levels of <30 a="" and="" association="" consequently="" for="" href="http://en.wikipedia.org/wiki/Voice_stress_analysis#cite_note-6#cite_note-6" is="" lva="" membership="" non="" of="" polygraph="" qualifying="" sa.="" stress="" technology="" the="" title="" to="" voice="">[7]
, the consumer version of the LVA technology, is available in different products and produces non-useful readings such as 'love' and 'Embarrassment' (not relevant in DOD applications).[8]The main difference in the method of operation between LVA and VSA is based on the analyzed frequencies ranges: while VSA focuses on the 8-14 Hz range (which is picked up by specialised microphones), LVA uses a wider spectrum range to extract information that is amusing but not particularly relevant to DOD.
