The Speech and Cognition Department of GIPSA-lab is a leading site for singing-voice research in France, linked to several laboratories in France and abroad. Several experimental platforms have been developed at the Speech and Cognition Department of GIPSA-lab to study voice and speech, communication behaviors in the case of human-human or computer-human interaction, and to evaluate physical models of human voice production. Selected studies conducted on the singing voice at the Speech and Cognition Department of GIPSA-lab will now be briefly described. All these studies result from national and/or international collaborations.
