Anti-Voice Adaptation Suggests Prototype-Based Coding of Voice Identity

Anti-Voice Adaptation Suggests Prototype-Based Coding of Voice Identity

We used perceptual aftereffects induced by adaptation with anti-voice stimuli to investigate voice identity representations. Participants learned a set of voices then were tested on a voice identification task with vowel stimuli morphed between identities, after different conditions of adaptation. In Experiment 1, participants chose the identity opposite to the adapting anti-voice significantly...

Norm-Based Coding of Voice Identity in Human Auditory Cortex

Listeners exploit small interindividual variations around a generic acoustical structure to discriminate and identify individuals from their voice-a key requirement for social interactions. The human brain contains temporal voice areas (TVA) involved in an acoustic-based representation of voice identity, but the underlying coding mechanisms remain unknown. Indirect evidence suggests that identi...

Voice Coding with Opus

In this paper, we describe the voice mode of the Opus speech and audio codec. As only the decoder is standardized, the details in this paper will help anyone who wants to modify the encoder or gain a better understanding of the codec. We go through the main components that constitute the voice part of the codec, provide an overview, give insights, and discuss the design decisions made during th...

Anti-spoofing, Voice Databases

As with any task involving statistical pattern recognition, the assessment of spoofing and anti-spoofing approaches for voice recognition calls for significantscale databases of spoofed speech signals. Depending on the application, these signals should normally reflect spoofing attacks performed prior to acquisition at the sensor or microphone. Since the collection of large quantities of any bi...
