The McGurk illusory percept is obtained by dubbing an incongruent articulatory movement onto an auditory signal. The Mismatch Negativity (MMN) of the auditory Event-Related Potential (ERP) reflects the detection of a deviant stimulus within auditory short-term memory (STM) and besides an acoustic component, possesses, under certain conditions, a phonetic one. The present study assessed the exis...

This study examined the influence of mixing faces and voices on the audiovisual intelligibility. The goal is to study the effect of combining two sources of information on the audiovisual intelligibility. Cross-talker dubbing was performed between faces and voices of 10 meaningful sentences pronounced by 10 talkers: 5 females and 5 males. Human subjects were asked to rate the articulation of th...

Voice conversion (VC) is an area of speech processing that deals with the conversion of the perceived speaker identity. In other words, the speech signal uttered by a first speaker, the source speaker, is modified to sound as if it was spoken by a second speaker, referred to as the target speaker. The most obvious use case for voice conversion is text-to-speech (TTS) synthesis where VC techniqu...

This paper describes a technique to obtain a time dilation or contraction of an audio signal. Different Computer Graphics applications can take advantage of this technique. In real-time networked VR applications, such as teleconference or games, audio might be transmited independently from the rest of the data, These different signals arrive asynchronously and need to be somehow resynchronized ...

This study examined sources of talker differences in the McGurk effect, by questioning which of auditory speech or visual speech is more determining the size of the McGurk effect. Cross-talker dubbing was done between faces and voices of utterances (/ba/ and /ga/) pronounced by two talkers: one compelling talker (CT) to the McGurk effect, and one less compelling talker (LT), as measured in our ...
