Abstract

The invention relates to a voice endpoint detection method and device, computer equipment and a storage medium. The method comprises the steps that a voice signal with noise is acquired, and an acoustic characteristic and a spectrum characteristic which correspond to the voice signal with the noise are extracted; the acoustic characteristic and the spectrum characteristic are converted, and a corresponding acoustic characteristic vector and a corresponding spectrum characteristic vector are obtained; a classifier is acquired, the acoustic characteristic vector and the spectrum characteristic vector are input to the classifier, and an acoustic characteristic vector with a voice label and a spectrum characteristic vector with a voice label are obtained; the acoustic characteristic vector with the voice label and the spectrum characteristic vector with the voice label are parsed, and corresponding voice signals are obtained; according to time sequences of the voice signals, an initial point and a termination point which correspond to the voice signals are determined. By adopting the method, the accuracy of voice endpoint detection can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of signal processing, in particular to a language endpoint detection method, device, computer equipment and storage medium. Background technique [0002] With the continuous development of speech technology, speech endpoint detection technology occupies a very important position in speech recognition technology. Speech endpoint detection is to detect the start point and end point of the speech part from a continuous noise speech, so that the speech can be recognized effectively. [0003] There are two traditional speech endpoint detection methods, one is to extract the characteristics of each segment of the signal according to the different characteristics of the time domain and frequency domain of the speech and noise signals, and compare the characteristics of each segment of the signal with the set threshold, so that Perform voice endpoint detection. However, this method is only suitable for d...
