SPEAKER RECOGNITION METHOD IN MULTI-CHANNEL SPEAKER RECOGNITION SYSTEM

摘要

PURPOSE: A speaker identification method for a multi-channel speaker identification system is provided to improve the performance of speaker identification and speaker verification in a remote distance multi-channel environment. CONSTITUTION: A speaker identifier for a multi-channel speaker identification system is connected to each input microphone(101). A speaker identification integrator(115) integrates the identification result of the speaker identifier. The channel speaker identifier computes the degree of speaker identification contribution by the measurement of posterior probability of a registered speaker. The speaker identification integrator produces channel reliability through speaker identification contribution. The speaker identification integrator integrates the channel speaker identification result with the weight application by the channel reliability.
