Embodiment Construction

[0021] The invention provides a method for adjusting a confidence threshold in speech recognition and an electronic device to solve the technical problem in the prior art that the speech recognition performance is low due to the fixed confidence threshold of speech recognition.

[0022] The technical solution in the embodiments of the present invention is to solve the above-mentioned technical problems, and the general idea is as follows:

[0023] By detecting one or more parameters (such as environment, scene, sentence itself) in real time, one or more detection results are obtained, and then the confidence threshold is adjusted according to one or more detection results of these results, so that the confidence threshold can be From a first value to a second value, wherein the second value is the same as or different from the first value. In this way, the confidence threshold can be changed to a confidence threshold adapted to the environment, scene or sentence according to d...

Abstract

The invention provides a method for adjusting a confidence coefficient threshold of voice recognition and an electronic device. The method for adjusting the confidence coefficient threshold of voice recognition is applied to the electronic device which supports voice recognition. The current confidence coefficient threshold of voice recognition serves as a first value. The method for adjusting the confidence coefficient threshold of voice recognition comprises the steps of detecting N parameters to obtain N detection results, wherein the N is an integer larger than or equal to one; adjusting the confidence coefficient threshold on the basis of at least one of the N detection results so that the confidence coefficient threshold can be changed from the first value into a second value, wherein the second value is equal to or different from the first value.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method for adjusting a confidence threshold in speech recognition and electronic equipment. Background technique [0002] With the development of electronic device technology, various electronic devices have entered the life of users. With the development of voice recognition technology, there are more and more scenarios where users control electronic devices or interact with electronic devices by voice. People's lives have brought great convenience. [0003] In the case of voice control or voice interaction, voice recognition is a very important step. In the process of voice recognition, the recognition result needs to be confirmed, that is, the confidence score of the recognition result is compared with the confidence threshold to decide whether to accept the recognition As a result, when the confidence score of a confirmed recognition result is greater than the confidence...
