Abstract

The disclosure relates to a speech recognition model determination method and device, a speech recognition method and device, and electronic equipment, and relates to the field of speech recognition.The speech recognition model determination method comprises the following steps: acquiring sample speech data; framing the sample voice data, and performing feature extraction on each frame of samplevoice data obtained by framing to obtain voice features of each frame of sample voice data; aligning the voice features of each frame of sample voice data based on syllables to obtain syllable labelscorresponding to each frame of sample voice data; and recognizing the voice features of each frame of sample voice data by using a to-be-trained voice recognition model to obtain a prediction syllablecorresponding to each frame of sample voice data. By adopting the method, the accuracy of speech recognition can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of speech recognition, and in particular to a method for determining a speech recognition model, a speech recognition method and device, and electronic equipment. Background technique [0002] Automatic Speech Recognition (ASR) is the process of converting human speech into corresponding text through algorithms. In the current automatic speech recognition system, the commonly used speech recognition model modeling methods include chain modeling, connection time series classification, etc., and the commonly used modeling unit is phoneme or phoneme state. [0003] In related technologies, speech recognition models use phonemes as modeling units and consider context-dependent phonemes. However, due to the short duration of phonemes, it is difficult to model the long-term time dependence of human speech due to the short duration of phonemes. The matching degree of speech perception is not high enough, ...
