Impersonation – reproduction of speech

A Phonetic Case Study of Impersonation

To use impersonation in order to entertain it is necessary to be aware of the target speaker’s speech behaviour and characteristic features. Does a professional impersonator really change his own voice quality and speech behaviour substantially in his impersonation, or does he only exaggerate some features of the target speaker to cheat and entertain the audience? The results of this analysis p...

Robust speaker identification against computer aided voice impersonation

Speaker Identification (SID) systems offer good performance in the case of noise free speech and most of the on-going research aims at improving their reliability in noisy environments. In ideal operating conditions very low identification error rates can be achieved. The low error rates suggest that SID systems can be used in real-life applications as an extra layer of security along with exis...

Voice Impersonation using Generative Adversarial Networks

Voice impersonation is not the same as voice transformation, although the latter is an essential element of it. In voice impersonation, the resultant voice must convincingly convey the impression of having been naturally produced by the target speaker, mimicking not only the pitch and other perceivable signal qualities, but also the style of the target speaker. In this paper, we propose a novel...

Voice Disguise vs. Impersonation: Acoustic and Perceptual Measurements of Vocal Flexibility in Non Experts

The aim of this study is to assess the potential for deliberately changing one's voice as a means to conceal or falsify identity, comparing acoustic and perceptual measurements of carefully controlled speech productions. Twenty-two non expert speakers read a phoneticallybalanced text 5 times in various conditions including natural speech, free vocal disguise (2 disguises per speaker), impersona...
