Problems solved by technology

In the general speech recognition process, for example, in the scenario where a child or a user who speaks slowly and does not express himself fluently interacts with the device, the user starts to perform speech recognition before the expression is completed, resulting in a low success rate of speech recognition

Embodiment Construction

[0062] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0063] This embodiment provides a voice boundary detection method assisted by a sound image, such as figure 1 shown, including the following steps:

[0064] S1: Receive the voice information of the target user.

[0065] S2: Extracting audio image information in the received audio information. In this embodiment, the voice image information extracted according to the user's voice includes age, speech speed, and expression fluency information, where the speech speed is divided into fast, medium, and slow, and the expression fluency is divided into good, medium, and low.

[0066]S3: Based on the speech recognition scoring model, identify and score all the target item...

Abstract

The invention provides a voice boundary detection method assisted by a voice portrait. The method comprises the following steps: S1, receiving voice information of a target user; S2, extracting voiceportrait information in the received voice information; S3, based on a voice recognition scoring model, recognizing and scoring all target items in the extracted voice portrait information one by one,and obtaining a comprehensive score; and S4, according to the comprehensive scoring result, obtaining a voice boundary detection duration related to the target user. According to the voice boundary detection method and device assisted by the voice portrait, the voice boundary detection duration matched with different users can be determined according to the different users, so that the voice recognition success rate is increased, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of voice boundary detection, in particular to a voice boundary detection method assisted by a sound image. Background technique [0002] Voice boundary detection is voice activity detection (Voice Activity Detection, vad), also known as voice endpoint detection. In the general speech recognition process, for example, in the scenario where a child or a user who speaks slowly and has poor language expression interacts with the device, the user starts to perform speech recognition before the expression is completed, resulting in a low success rate of speech recognition. At this time, it is necessary to detect the duration of the speech boundary detection, so as to improve the success rate of speech recognition. Contents of the invention [0003] In order to overcome the above problems, the present invention provides a voice boundary detection method assisted by a voice image, which specifically includes the ...
