Abstract:
Disclosed are a speech segmentation method and device. The speech segmentation method comprises: when a mixed speech sent by a terminal is received, segmenting the mixed speech into a plurality of phrase segments, and labelling each phrase segment with a corresponding speaker identifier (S1); and using a recurrent neural network to build a voiceprint model for the phrase segment corresponding to each speaker identifier, and adjusting a corresponding segmentation boundary in the mixed speech based on the voiceprint model so as to segment out an effective speech segment corresponding to each speaker identifier (S2). The method can effectively improve the precision of speech segmentation and has a better speech segmentation effect especially on frequently alternate conversations and overlapping speeches.
