Problems solved by technology

Among them, for the Chinese-English mixed acoustic model, a large amount of Chinese-English mixed speech and annotation data are required as training materials, but compared with Chinese (single language) training data, Chinese-English mixed data is very rare, and retraining a Chinese-English The cost of the special acoustic model for mixed recognition is also relatively high. In addition, it is also a difficult problem to merge the Chinese and English phoneme sets, which are the modeling units of the Chinese and English acoustic models. If the conventional English acoustic model (between English words and English phonemes Mapping) to identify, but also need to switch models, affecting the recognition time
In addition, there is a problem that the English pronunciation of Chinese-speaking speakers is different from that of English-speaking speakers.
[0004] For the above-mentioned problems existing in related technologies, no effective solution has been found yet

Abstract

The present invention provides a mixed speech recognition method and device, a storage medium, and an electronic device, wherein the method includes: obtaining a mixed speech to be recognized by phonemes, wherein the mixed speech includes Chinese words and English words; from the Extracting English non-abbreviated words from the mixed voice; using the first preset grapheme sequence to phoneme sequence G2P model to identify the first phoneme information of the English non-abbreviated word, wherein the first preset G2P model is decoded by Chinese phonemes The results are trained, including the mapping sequence between English words and Chinese phonemes. Through the present invention, while saving labor costs, the acoustically highly similar mapping labels are pursued, and a quality-reliable English pronunciation solution is realized. The technical problem of low efficiency of phoneme recognition of mixed speech in the related art is solved.

Description

technical field [0001] The present invention relates to the field of voice recognition, in particular, to a hybrid voice recognition method and device, a storage medium, and an electronic device. Background technique [0002] In related technologies, Chinese-English mixed speech recognition refers to Automatic Speech Recognition (ASR, Automatic Speech Recognition) that includes both Chinese and English languages ​​in the process of speaking to the speaker. Today, as English is becoming more and more popular, for most Chinese people In other words, mixed communication in Chinese and English has gradually become a common phenomenon. In the Chinese-English dialogue among Chinese people, the Chinese part is still the main language. According to the type of switching between Chinese and English, it can be divided into "sentence switching", that is, English words are interspersed in Chinese sentences, and the other is "inter-sentence switching", that is, Chinese There is a switch...
