Abstract:  This study was designed to evaluate commonly used voice stress analyzers—in this case the layered voice analysis (LVA) system. The research protocol involved the use of a speech database containing materials recorded while highly controlled deception and stress levels were systematically varied. Subjects were 24 each males/females (age range 18–63 years) drawn from a diverse population. All held strong views about some issue; they were required to make intense contradictory… Expand
Assessing Deception by Voice Analysis: Part II: The LVA
This overview is the second of a two-part series designed to brief law enforcement personnel, attorneys and members of the intelligence services about the ability of voice analyzers to detectExpand
Vocalic markers of deception and cognitive dissonance for automated emotion detection systems

In the present exploratory study, we investigated acoustic–phonetic measures of spoken vowels for detection of female speech under conditions of stress. Eight authentic recorded calls to emergencyExpand
Vocal indices of stress: a review.
Stress types, gender, and individual differences in baseline autonomic tone may explain the primarily equivocal findings of effects of stressor exposure or perceived stress on voice; and as such, the article concludes with a discussion of directions for future study. Expand
Investigating the Acoustic Characteristics of Deceptive Speech
The changes in the speech signal when people were being deceptive were explored to encourage researchers and practitioners to evaluate critically what is (im)possible using auditory and machine based analyses with respect to detecting deception from speech. Expand
Acoustic Correlates of Deceptive Speech - An Exploratory Study
The study attempted to investigate the appropriateness of using speech cues in detecting deception, and results are presented on a range of speech parameters including fundamental frequency, overall intensity and mean vowel formants. Expand
Affective State and Voice: Cross-Cultural Assessment of Speaking Behavior and Voice Sound Characteristics - a Normative Multicenter Study of 577 + 36 Healthy Subjects
The normative data showed that speaking behavior and voice sound characteristics can be quantified in a reproducible and language-independent way and demonstrated the feasibility and efficiency of the speech analysis method in home environments, thus clearing the way to a broader range of applications in psychiatry.

A Preliminary Study on the Feature Distribution of Deceptive Speech Signals
A preliminary study is conducted to compare the feature distribution between normal and deceptive speech, and the results are reported in this paper. The objective of this research is to show thatExpand
Detecting suspicious behaviour using speech: acoustic correlates of deceptive speech -- an exploratory investigation.
The study attempted to investigate the appropriateness of using speech cues in detecting deception, and a significant correlation could not be established between deceptiveness/truthfulness and any of the acoustic features examined. Expand
Issues in forensic voice.
The following article provides a general review of an area that can be referred to as Forensic Voice, the processing and analysis of spoken utterances, distorted speech, enhancement of speech intelligibility, transcripts, and the detection of deception, intoxication, and emotions in speech.

Evaluation of the NITV CVSA
Evaluating a commonly used voice stress analyzer, the National Institute of Truth Verification’s (NITV) Computer Voice Stress Analyzer (CVSA), using a speech database containing materials recorded in the laboratory, demonstrated that the CVSA system operated at about chance level. Expand
Voice stress evaluators and lie detection.
A series of experiments on the detection of relatively high-risk lies by commercial voice analyzers found that correct stress/nonstress identifications occurred only at chance levels; the lie/nonlie identification scores were quite similar with professional "examiners" performing at about the same level of accuracy as other auditors.

The aim of this research was to analyze the main vocal cues and strategies used by a liar. 31 male university students were asked to raise doubts in an expert in law about a picture. The subjectsExpand

Pitch changes during attempted deception.
It was shown that the average voice fundamental frequency of the subjects was higher when lying than when telling the truth, and accuracy differences were found that depended on how an utterance had been elicited originally. Expand
