Identification of voices in electronically disguised speech

International Journal of Speech Language and the Law, 2008
We describe an experiment on the effects of electronic vocal disguise on speaker identification. 36 listeners were trained to identify four voices. They then participated in listening tests in which their task was to identify speakers in a set of short stimuli. In the first test the stimuli were natural.

A report on a voice disguise experiment

The International Journal of Speech, Language and the Law, 1996
Voice disguise is potentially present in any speech-specific criminal case. Appropriate methods of analysing and evaluating voice disguise therefore are necessary. An experiment was conducted in which 20 subjects provided samples of their modal as well as disguised voices.

Verification of hidden speaker behind transformation disguised voices

Digital Signal Processing, 2015
We investigate the effects of voice transformation disguise on ASV performance.We propose an algorithm to estimate transformation factor.We propose an algorithm to restore the genuine acoustic characteristics.We integrate the above algorithms into GMM-UBM based ASV system.The proposed approach achieves 3-4% EER.

Detection of Voice Transformation Disguise Based on Deep Residual Net

Proceedings of the 2020 4th International Conference on Cryptography, Security and Privacy, 2020
Voice transformation (VT) disguise is used for de-identification which can easily deceive state-of-the-art automatic speaker verification (ASV) systems by dramatically increasing false reject rates, and thus it presents serious threats to social security. However, the researches on VT detection are insufficient.

Identification of Electronic Disguised Voices in the Noisy Environment

2017
Since voice disguise has been an increasing tendency in illegal application, which brings great negative impact on establishing the authenticity of audio evidence for audio forensics, especially in noisy environment. Thus it is very important to have the capability of identifying whether a suspected voice has been disguised or not. However, few studies

Acoustic analysis of whispery voice disguise in Chinese

The Journal of the Acoustical Society of America, 2017
This paper investigates the auditory and acoustical features of disguised whispery voices, the acoustic difference between normal (non-disguised) voices and whispery voices, and the effect of whispery disguise on forensic speaker recognition. Recordings of eleven male college students’ normal voices and whispery disguised voices were collected.

On trying to disguise the voice with a dental appliance

The Journal of the Acoustical Society of America, 1974
As part of a beginning study on speech adaptation to dental appliances, four young adults were fitted with an experimental alveolar-palatal acrylic appliance similar to an orthodontic retainer. They wore the appliance for one week in an attempt to learn to speak normally with it.

Acoustic analysis of disguised voices with raised and lowered pitch

2012 8th International Symposium on Chinese Spoken Language Processing, 2012
Change of pitch is a common disguise type adopted by criminals in forensic voice comparison, which introduces substantial variance of acoustic properties and results in poorer performance of speaker recognition. This paper investigates the acoustic properties of disguised voices with raised and lowered pitch from 11 Chinese male speakers.
