Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A speech processing method, performed by an electronic device, the method comprising:
determining a first speech feature and a first text bottleneck feature based on to-be-processed speech information;
determining a first combined feature vector based on the first speech feature and the first text bottleneck feature, wherein the determining the first text bottleneck feature based on the to-be-processed speech information comprises:
extracting an N-dimensional filter-bank feature and an M-dimensional pitch feature from the to-be-processed speech information, wherein N and M are positive integers,
splicing the N-dimensional filter-bank feature and the M-dimensional pitch feature to obtain a second speech feature,
inputting the second speech feature into a trained automatic speech recognition (ASR) network, and
extracting the first text bottleneck feature from a linear layer of a bottleneck of the trained ASR network;

inputting the first combined feature vector to a trained unidirectional long short-term memory (LSTM) model;
performing speech processing on the first combined feature vector to obtain speech information after noise reduction; and
transmitting the obtained speech information after noise reduction to another electronic device for playing.
