Problems solved by technology

Among them, the corpus in the general language model is generally complex, the update speed is slow, and it is not targeted, resulting in low accuracy of speech recognition results
Especially for homophonic or similar speech, the existing speech recognition technology cannot provide accurate recognition results. For example, the collected speech of the user is "xinxinjie", the existing speech recognition technology cannot judge the speech Whether the text corresponding to the voice is "Xinxing Street" or "Xinxin Street" or other similar texts

Embodiment Construction

[0054] The present invention will be described in further detail below in conjunction with the accompanying drawings. Those of ordinary skill in the art will appreciate that although the following detailed description refers to the illustrated embodiments and accompanying drawings, the present invention is not limited to these embodiments. Rather, the scope of the invention is broad and it is intended that the scope of the invention be limited only by the appended claims.

[0055] figure 1 Shows a schematic block diagram of speech recognition in the prior art, the following figure 1 The speech recognition technology shown is briefly explained.

[0056] according to figure 1 , in the prior art, a voice database and a text database are usually established respectively based on a large amount of voice data and text data, and the acoustic model is trained by extracting voice features from the voice data, and the language model is trained using the text data. When the input spe...

Abstract

The invention provides a real-time voice recognition system and method. The real-time voice recognition method includes the steps of: collecting current voice and current scene information of a current user; constructing a current scene language model corresponding to the current user; judging the type of the current scene according to the current scene information, and searching a static language model corresponding to the type of the current scene from static language models corresponding to different scene types which are constructed according to historical scene information; and calling a universal language model, and recognizing voice of the current user based on a hybrid and acoustic model of the universal language model, the searched static language model and the scene language model corresponding to the current user. The real-time voice recognition method constructs language models in an offline and online combination manner based on various scene information, and thus can effectively improve the accuracy rate of voice recognition.

Description

technical field [0001] The invention relates to speech recognition technology, in particular to a scene-based real-time speech recognition system and method. Background technique [0002] In existing speech recognition, a general language model based on corpus in various fields is usually combined with a corresponding acoustic model to recognize the text corresponding to the speech. Among them, the corpus in the general language model is generally complex, the update speed is slow, and it is not targeted, resulting in low accuracy of speech recognition results. Especially for homophonic or similar speech, the existing speech recognition technology cannot provide accurate recognition results. For example, the collected speech of the user is "xinxinjie", the existing speech recognition technology cannot judge the speech Whether the text corresponding to the voice is "Xinxing Street" or "Xinxin Street" or other similar texts. Contents of the invention [0003] One of the te...
