When a sound sequence arrives at a listener’s ears, he/she will perceive it as one or more auditory streams, generally corresponding to one or more sound sources. Sounds originating alternately from a target and competing source will need to be separated into two streams for the target to be intelligible. In rooms, reverberation leads to temporal and spectral distortions of speech signals. We want to investigate to which extend these distortions deteriorate the segregation/streaming of competing voices. Listening tests will be designed to evaluate the influence of reverberation on segregation mechanisms based on fundamental frequency differences and differences in source positions. References *A. S.
