Problems solved by technology

[0003] However, due to the continuous update of the surrounding environment and current affairs background, many new phrases will appear, such as popular Internet words such as Shanzhai, Leiren, and Diaosi. Therefore, still using the existing speech model for speech recognition will lead to these new phrases. The recognition accuracy of the phrase is reduced, which leads to a reduction in the reliability of speech recognition

Abstract

The invention provides a user behavior log-based method and a user behavior log-based device for updating a voice model. According to the embodiment of the invention, high-frequency word groups and/or new word groups are extracted according to an acquired user behavior log, further, a word list is updated according to the high-frequency word groups and/or the new word groups, so that the voice model can be trained by utilizing the updated word list, and thus, voice recognition can be performed by utilizing a trained new voice model, and as the word list is updated according to the user behavior log, the new voice model can be trained, and thus, the problem that the voice recognition accuracy is reduced by adopting a traditional voice model due to the fact that the new word groups arise in the prior part can be avoided, and therefore, the reliability of the voice recognition is improved.

Description

【Technical field】 [0001] The invention relates to speech recognition technology, in particular to a speech model updating method and device based on user behavior logs. 【Background technique】 [0002] With the development of communication technology, the terminal integrates more and more functions, so that the system function list of the terminal includes more and more corresponding applications, for example, applications installed in the computer, third-party smart phones Installed applications (Application, APP), etc. Some applications involve some voice recognition services, for example, voice input in instant messaging software such as QQ and WeChat, and voice input in Baidu Maps. In the prior art, the speech processing engine can use the received speech data as an input to run a speech model to obtain a recognition result. [0003] However, due to the continuous update of the surrounding environment and current affairs background, many new phrases will appear, such as...
