Title:
NEURAL NETWORK SPEECH RECOGNITION METHOD AND SYSTEM ORIENTED TO HOME SPOKEN ENVIRONMENT
Document Type and Number:
WIPO Patent Application WO/2021/208455
Kind Code:
A1
Abstract:
A neural network speech recognition method and system oriented to a home spoken environment, comprising: model construction: adding a long-short-term memory network into a deep neural network, to construct a combined neural network DNN-LSTM model; pre-processing an acquired speech data set to obtain a feature vector set, and using the feature vector set as an input of the DNN-LSTM model to perform iterative training, so as to train same to an optimal acoustic model; causing an input speech signal of an unknown language to be subjected to the trained DNN-LSTM model to respectively obtain a Chinese output probability vector set and an English output probability vector set; performing language matching according to the Chinese output probability vector set and the English output probability vector set, and outputting a determination result. The present invention is able to quickly and accurately recognize content of a speaker in a home scene, and can be widely applied to an actual home scene.
