Abstract

The invention discloses a voice end node detection method and device. The voice end node detection method comprises the following steps: acquiring to-be-detected audio frequency in targeted environment; utilizing a voice training model generated in advance to mark the audio clips in the to-be-detected audio frequency; marking the voice clips in the to-be-detected audio frequency as first pre-arranged identification, wherein the voice training model is a model obtained from training of the voice data in the targeted environment; searching the whole segment of audio frequency provided with the first pre-arranged identification in the marked to-be-detected audio frequency, wherein the whole audio frequency is the whole segment of voice marked with the first pre-arranged identification; taking the whole segment of audio frequency provided with the first pre-arranged identification as a segment of voice; taking the starting node and the end node of the whole segment of the audio frequency provided with the first pre-arranged identification as the end nodes of the voice. According to the invention, the problem in the prior art that the voice end node detection accuracy is relatively low under the condition of high noise is solved; the voice end node detection accuracy is improved.

Description

technical field [0001] The invention relates to the field of voice detection, in particular to a voice endpoint detection method and device. Background technique [0002] At present, for speech recognition, most audio frequency features such as cepstral coefficients are used to implement endpoint detection. Such a detection method usually has a better effect when the background noise is small. However, when the noise of the voice background is very large (for example, the signal-to-noise ratio is 0 decibels), the endpoint detection effect is obviously reduced, and the accuracy of the voice endpoint detection is low. [0003] Aiming at the problem of low accuracy of speech endpoint detection in the prior art, no effective solution has been proposed yet. Contents of the invention [0004] The main purpose of the present invention is to provide a voice endpoint detection method and device to solve the problem of low accuracy of voice endpoint detection in the prior art.
