Title:
SPEECH PROCESSING METHOD AND APPARATUS BASED ON GENERATIVE ADVERSARIAL NETWORK
Document Type and Number:
WIPO Patent Application WO/2021/046683
Kind Code:
A1
Abstract:
A speech processing method and apparatus based on a generative adversarial network, the method comprising: acquiring speech training samples, the speech training samples comprising N sets of complete speech samples and packet loss speech samples corresponding to the complete speech samples and K sets of wideband speech samples and narrowband speech samples corresponding to the wideband speech samples (S101); inputting the speech training samples into a generative adversarial network, and respectively performing packet loss compensation model training on the basis of the packet loss speech samples and the complete speech samples and frequency band expansion model training on the basis of the wideband speech samples and the narrowband speech samples to acquire a speech processing system formed of a packet loss compensation model and a frequency band expansion model (S102); and, by means of the speech processing system, processing original speech to be processed and acquiring enhanced speech after packet loss compensation or frequency band expansion (S103). The processing efficiency of packet loss compensation based on packet loss speech and the processing performance of frequency band expansion based on narrowband speech in speech processing can thereby be improved.
