Problems solved by technology

[0002] At present, when recognizing speech, the confidence level of the speech recognition result is usually used, but the confidence level in the related art is preset and fixed, which not only increases the user's operation burden, but also because the confidence level is fixed , therefore, once the confidence level is set unreasonably, it will affect the effectiveness of the recognition results, for example, if the confidence level is set low, it will cause misidentification

Abstract

The invention relates to a voice recognition method and device. The method comprises the following steps: receiving an input first voice; recognizing the first voice to obtain a first voice recognition result and a current first confidence coefficient of the first voice recognition result; obtaining a trainable confidence coefficient corresponding to the first voice; and based on the first confidence coefficient and the trainable confidence coefficient, judging whether the first voice recognition result is valid or not. Through the technical scheme of the invention, the judgment accuracy of the effectiveness of the first voice recognition result can be improved, the misjudgment rate of the first voice recognition result can be reduced, and meanwhile, the confidence coefficient can be prevented from being manually set.

Description

technical field [0001] The invention relates to the field of voice technology, in particular to a voice recognition method and device. Background technique [0002] At present, when recognizing speech, the confidence level of the speech recognition result is usually used, but the confidence level in the related art is preset and fixed, which not only increases the user's operation burden, but also because the confidence level is fixed , therefore, once the confidence level is set unreasonably, it will affect the validity of the recognition result, for example, if the confidence level is set low, it will cause misidentification. Contents of the invention [0003] The embodiment of the present invention provides a voice recognition method and device. Described technical scheme is as follows: [0004] According to a first aspect of an embodiment of the present invention, a speech recognition method is provided, including: [0005] receiving an input first voice; [0006] ...
