Embodiment Construction

[0045] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0046] In some application scenarios where the model cannot be pre-customized, such as meeting scenarios, if the general language model is used for speech recognition, the recognition effect is not ideal, especially for entity words such as person names, place names, product names, and some professional nouns contained in the speech data. In some cases, recognition errors often occur, and errors in speech recognition will lead to errors in subsequent machine translations.

[0047] For example: Regarding Gaussian, whether Gaussian here is a person's name or a Gaussian function on data, the translations of the two are completely different;

[0048] For example: Xiaoai speaker, when this product first appeared, w...

Abstract

The invention discloses a voice recognition method and device. The method comprises the steps: receiving voice data of a speaker, and acquiring a text material related to the voice data; extracting akeyword in the text material; and performing voice recognition on the voice data by using a decoding network, adjusting scores of decoding paths in the decoding network according to the keyword, and acquiring a voice recognition text according to the scores of the decoding paths. By utilizing the scheme of the invention, the accuracy of the speech recognition result can be greatly improved.

Description

technical field [0001] The invention relates to the field of voice recognition, in particular to a voice recognition method and device. Background technique [0002] At present, with the development of artificial intelligence technology, machine simultaneous interpretation has appeared. The biggest advantage of machine simultaneous interpretation is that it will not reduce the translation rate due to fatigue. Machine simultaneous interpretation is limited by speech recognition technology and machine translation technology, and the quality of machine translation depends on the quality of speech recognition text. Therefore, in order to improve the accuracy of machine simultaneous interpretation, it is necessary to have a high-quality speech recognition system. In some machine simultaneous interpretation application scenarios, it is often encountered the problem of recognition and translation of substantive words or professional nouns such as names of people, places, and produc...
