Abstract

The embodiment of the invention relates to a voice signal processing method and device and a storage medium. The method comprises the steps of obtaining audio characteristics of a to-be-detected frame; obtaining a mute point proportion in a preset length time window before the to-be-detected frame in a voice signal; determining a mute point proportion threshold value according to the audio characteristics; and judging whether the to-be-detected frame is a tail point frame or not according to the mute point proportion and the mute point proportion threshold. According to the embodiment of the invention, the mute point proportion in the preset length time window can be utilized, and the cepstrum characteristic of the current to-be-detected frame is used for dynamically adjusting the mute point proportion threshold, so that the problem of inaccurate voice tail point detection existing in a fixed mute point proportion threshold is solved, and the accuracy and real-time performance of tailpoint frame detection are effectively improved.

Description

technical field [0001] The embodiments of the present application relate to but are not limited to the field of computer technologies, and in particular, relate to a voice signal processing method, device, and storage medium. Background technique [0002] With the development of artificial intelligence, speech recognition has become the standard configuration of many devices. Speech recognition takes speech as the research object. Through speech signal processing and pattern recognition, machines can automatically recognize and understand human-dictated language. [0003] Speech end point detection plays a key role in speech recognition. Speech end point detection is to find the end point of speech in audio data, and its accuracy plays a vital role in the accuracy of speech recognition. [0004] At present, there is a problem that the voice end point detection is not easy to determine, which greatly reduces the accuracy of speech recognition. Contents of the invention [...
