Acoustical measurements exist to predict = the intelligibility of a solitary voice in a room, but none takes into acco= unt the presence of competing voices (cocktail-party situations). Such a me= asurement would be helpful to improve communication, security and comfort i= nside buildings, as well as their accessibility for hearing-impaired people= . Recent work* allowed us to predict the intelligibility of a voice in the pr= esence of multiple noise sources. We now aimed at more common (and complex)= situations involving competing speech sources: predict the intelligibility= of a voice within other voices in a room. Segregation mechanisms based on = amplitude modulation of the interferers and pitch differences between the c= ompeting voices would need to be described (design and analysis of controll= ed listening tests), and the influence of reverberation on these mechanisms= would need to be modeled (measure and simulation in room acoustics). In pa= rallel to this development of the intelligibility model, we would like to t= est it for evaluating room quality. This would require the simulation of co= cktail-party situations, and the comparison with acoustical measurements do= ne in real situations (social meetings, restaurants ...). *Lavandier, Jelfs, Culling, Watkins, Raimond and Makin (2012) Binaural pred= iction of speech intelligibility in reverberant rooms with multiple noise s= ources, J.
