Voice disguise and automatic speaker recognition
Forensic Science International, 2008In 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.

Identification of Electronic Disguised Voices
IEEE Transactions on Information Forensics and Security, 2014Since 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, 2008State 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 ...

FASR: Effect of voice disguise
2016 International Conference on Emerging Technological Trends (ICETT), 2016Speaker recognition systems based on spectral features perform well in acoustically matched and noise-free conditions. Spectral features are unsuccessful to model information about the speaker at higher levels. Prosody which represents intonation, rhythm and stress of speech, better represents speaker characteristics at higher levels. Voice disguise is

Articulation During Voice Disguise: A Pilot Study
2021Speakers 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 Spectrograms as a Function of Age, Voice Disguise, and Voice Imitation
The Journal of the Acoustical Society of America, 1971In 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 ...

Blind detection of electronic disguised voice
2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013Since voice disguise has great negative impact on establishing authenticity of audio evidence in forensics, and has shown an increasing tendency in illegal applications, it is important to identify whether a suspected voice has been disguised or not. However, research on such detection has not been reported.
