Problems solved by technology

[0003] At present, multiple recognition results are sorted mainly according to the matching rate of the input voice information and the voice model in the voice model library from high to low. For example, in Baidu search, no matter which search category the input voice information will get sequence of recognition results; according to the current sorting method, among the recognition results provided to users, the top-ranked results are not the optimal results, and the user needs to further interact with the search server to perform manual screening or re-enter voice information to search, thereby As a result, the speech recognition rate of the search server is low, and the user's repeated input of voice information will also increase the load of the search server

Abstract

The invention provides a speech recognition method which comprises the following steps of: receiving speech information and a recognition result type transmitted from a client; looking for a speech classification lexicon corresponding to the recognition result type from more than one preset speech classification lexicons, thus obtaining the recognition result from the found speech classification lexicon according to the speech information; and feeding back recognition results which are sequenced according to similarities from high to low to the client. The invention further provides a speech recognition system. According to the technical scheme provided by the invention, the speech recognition rate of application with the speech recognition function is improved.

Description

【Technical field】 [0001] The invention relates to the field of Internet applications, in particular to a voice recognition method and system. 【Background technique】 [0002] Speech recognition technology is one of the top ten important technological development technologies in the field of information technology in the past ten years. It is mainly used in voice dialing, voice navigation, indoor equipment control, voice search, dictation data entry, etc. Since the speech recognition process is intelligent, there may be cases of different words with the same pronunciation, so there will be multiple recognition results. When there are multiple recognition results, it is particularly important to sort the recognition results. [0003] At present, multiple recognition results are sorted mainly according to the matching rate of the input voice information and the voice model in the voice model library from high to low. For example, in Baidu search, no matter which search category ...
