Example Embodiment

[0061] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0062] In the process of implementing the present invention, the inventor found that most of the current speech recognition schemes are based on a single-language speech recognition model. The recognition scheme based on a single-language speech recognition model has a better recognition effect on single-language speech, but it is not The recognition effect of bilingual mixed speech is not good. For example, the recognition scheme based o...

Abstract

The application provides a bilingual hybrid speech recognition method, device and equipment and a storage medium. The method comprises the following steps: obtaining target speech, wherein the targetspeech is hybrid speech of a first language and a second language; recognizing the target speech by using a pre-established bilingual hybrid speech recognition model, and obtaining a plurality of candidate recognition texts and scores respectively corresponding to the plurality of candidate recognition texts, wherein the bilingual hybrid speech recognition model can determine a text classificationprobability and a language classification probability of each text unit in each candidate recognition text, and the score corresponding to any candidate recognition text is determined according to the text classification probability and the language classification probability of each text unit in the candidate recognition texts; and determining a target recognition text of the target speech fromthe plurality of candidate recognition texts according to the scores corresponding to the plurality of candidate recognition texts. The bilingual hybrid speech recognition method, device and equipmentand the storage medium in the application have a good recognition effect on bilingual hybrid speech, and the user experience is good.

Description

technical field [0001] The present application relates to the technical field of speech recognition, in particular to a bilingual mixed speech recognition method, device, equipment and storage medium. Background technique [0002] With the increasing maturity of artificial intelligence-related technologies, more and more smart devices have entered the lives of users, and the interaction between humans and machines has become increasingly common. Voice input is the most natural and convenient way in human-computer interaction. It can free hands and is loved by users. Most of the current smart devices have a voice recognition function, and the voice recognition function facilitates the lives of users. [0003] The current speech recognition scheme has a good recognition effect on speech in a single language. However, at some point, the speech to be recognized may not only be a speech in a single language, but may also be a mixed speech of two languages. For example, the conte...
