Problems solved by technology

[0005] However, not all voice interaction platforms support VAD recognition in the cloud, and the VAD of some voice interaction platforms needs to be processed by the front end
[0006] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

Abstract

The invention is suitable for the technical field of voice processing, and provides a method and system for detecting a voice endpoint, a storage medium and computer equipment, and the method for detecting the voice endpoint comprises the steps: collecting a first audio signal; detecting first energy of the first audio signal, and determining a transmission starting point of the first audio signal according to a first energy feature of the first energy; collecting a second audio signal behind the transmission starting point; and detecting second energy of the second audio signal, and determining a transmission termination point of the second audio signal according to a second energy feature of the second energy. According to the invention, the front end can detect the voice endpoint of the audio signal.

Description

Technical field [0001] The present invention relates to speech processing technology, and particularly relates to a method for detecting speech endpoint, system, storage medium, and computer equipment. Background technique [0002] Intelligent terminal devices such as smart speakers have a very basic question, when the smart speaker is awakened, accepting voice commands, is how to judge the start and end of the voice instruction. [0003] VAD (Voice Activity Detection) main task is accurate positioning of the noisy speech from the speech start and end points, because speech contains a long silence, i.e. the actual speech and silence separated, because it is the original voice data processing, so VAD is one of the key technologies of the speech signal processing. The first technical recognition or speech recognition system in the acoustic model training phase endpoint detection is encountered, the silence and noise is removed as an interference signal from the raw data, and the pe...
