Classification: CPC G | IPC G

Claim 11:
12. A non-transitory computer-readable storage medium storing computer instructions that, when executed by at least one processor of a device, cause the at least one processor to:
determine a first speech feature and a first text bottleneck feature based on to-be-processed speech information;
determine a first combined feature vector based on the first speech feature and the first text bottleneck feature, wherein the at least one processor is further configured to determine the first text bottleneck feature based on the to-be-processed speech information by:
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;

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