Simulation experiment:<\/u><\/strong><\/p>\n For the simulated data, clean anechoic speech signals were drawn from the TIMIT database. The speakers were randomly selected from a subset of 26 speakers. Speech utterances of the same speaker were concatenated to obtain a 5s long speech signal. The room dimensions were set to 6 x 4 x 3 m with reverberation time T60 ~ 200ms. The signals were captured by an eight-microphone linear array with inter-distances of [3, 3, 3, 8, 3, 3, 3] cm. The measured signals were contaminated by an additive babble diffuse noise with various SNR levels. Three moving speakers were simulated, with initial DOA set to 36, 90 and 144 degrees, respectively. The speakers moved from their initial positions along an arc of a circle with a radius of 1m from the array center. Their time-varying DOA has a sinusoidal form, with time period randomly selected between 1-2.5s, and amplitude also randomly selected between 5-8 degrees. We present audio samples from 3 random mixtures, with SNR of 5dB and 25dB.<\/p>\n \u00a0<\/p>\n SNR<\/strong><\/p>\n<\/td>\n Noisy Mixture <\/strong><\/p>\n<\/td>\n Clean - Speaker 1<\/strong><\/p>\n<\/td>\n Clean -Speaker 2<\/strong><\/p>\n<\/td>\n Clean -Speaker 3<\/strong><\/p>\n<\/td>\n<\/tr>\n 5 dB<\/p>\n<\/td>\n\n\n
