Articulation During Voice Disguise: A Pilot Study

Lecture Notes in Computer Science, 2021
Speakers can conceal their identity by deliberately changing their speech characteristics, or disguising their voices. During voice disguise, speakers alter their normal movements of the articulators, such as tongue positions, according to a predetermined strategy. Even though technology for accurate articulatory measurements has existed for years, few

Voice disguise and automatic speaker recognition

Forensic Science International, 2008
In this paper a newly developed Forensic Automatic Speaker Recognition System (FASRS) was introduced and the effect of 10 types of voice disguises that are common in forensic casework on the performance of this system was studied. In this study 10 types of disguised voices and normal voices from 20 male college students were used as test samples.

Formant manipulations in voice disguise by mimicry

2016 4th International Conference on Biometrics and Forensics (IWBF), 2016
The human voice can be disguised in many ways. The purpose of disguise could either be to impersonate another person, or to conceal the identity of the original speaker, or both. On the other hand, the goal of any biometric analysis on disguised voices could also be twofold: either to find out if the originator of the disguised voice is a given speaker,

Glottal fry and voice disguise: a case study in forensic phonetics

Journal of Biomedical Engineering, 1993
In recent legal proceedings, forensic phoneticians were called upon to analyse a tape-recorded message intended for the blackmail of a bank manager following the kidnap of his wife. The brief was to establish the likelihood that the tape recording may have been made by any one of three suspects, samples of whose speech were also made available.

Detecting the presence of vocal disguise in the male voice

Journal of the Acoustical Society of America, 1981
This research examined the ability of naive and sophisticated listeners to detect extemporaneous disguise in the male voice. The experimental stimuli were sentences uttered in an undisguised and in a freely disguised fashion. The listeners were asked to decide whether a sentence was disguised or undisguised and to rate his/her degree of confidence in ...

Identification of Electronic Disguised Voices

IEEE Transactions on Information Forensics and Security, 2014
Since voice disguise has been an increasing tendency in illegal applications, and it has a great negative impact on establishing the authenticity of audio evidence for audio forensics, it is important to be able to identify whether a suspected voice has been disguised or not. However, few studies on such identification have been reported. In this paper,

The question of disguised voice

The Journal of the Acoustical Society of America, 2008
State of the art automatic speaker recognition systems show very good results in the discrimination between different speakers under controlled recording conditions. In a forensic context, the conditions are uncontrolled and voice can be disguised. In cases of terrorism claim, extortion or kidnapping, it is of great interest for offenders to conceal ...

Voice Spectrograms as a Function of Age, Voice Disguise, and Voice Imitation

The Journal of the Acoustical Society of America, 1971
In order to determine if speech spectrograms can be used to identify human beings, two questions must be studied: (1) does the formant structure of phonemes uttered by a certain speaker change over a long interval of time, and (2) can the formant structure be changed by disguise, or is it even possible to imitate the formant structure of another ...
