Embodiment Construction

[0070] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0071] Speech endpoint detection is the front-end processing process of speech recognition. It is used to extract the human voice signal in the audio data and filter out signals that are useless for recognition such as noise or silence. The quality of speech endpoint detection directly or indirectly determines the effect of speech recognition. Specifically, if the speech signal is filtered, truncation errors will occur in recognition, and if too much noise is put in, insertion errors...

Abstract

The invention provides a speech endpoint detection method, device and equipment and a storage medium. The speech endpoint detection method comprises the steps of extracting audio features used for determining the dynamic detection interval from audio data to be detected to serve as dynamic detection interval features; determining attributes of the audio data to be detected through a pre-established audio attribute determination model according to the dynamic detection interval features, and determining the dynamic detection interval of the audio data to be detected through a pre-established dynamic detection interval model according to the dynamic detection interval features; and determining the speech endpoint of the audio data to be detected based on the attributes and the dynamic detection interval of the audio data to be detected. The speech endpoint detection method provided by the invention realizes speech endpoint detection based on the dynamic detection interval, has a good detection effect and is excellent in user experience.

Description

technical field [0001] The present application relates to the technical field of speech recognition, and in particular to a speech endpoint detection method, device, equipment and storage medium. Background technique [0002] Speech recognition is an important part of human-computer interaction. Speech recognition refers to the automatic conversion of speech into corresponding text through methods such as machine learning. [0003] With the advancement of artificial intelligence wave after wave, speech recognition, as an important field of artificial intelligence, is developing by leaps and bounds. Although speech recognition technology has reached the commercial stage, its recognition effect is still not satisfactory. One of the important reasons for this is that the detection effect of the current speech endpoint detection scheme is not good. [0004] Since speech endpoint detection is the front-end processing process of speech recognition, if the effect of speech endpoin...
