Abstract

The invention relates to the technical field of artificial intelligence, and discloses a voice endpoint detection method. The method comprises the following steps of: obtaining input voice to be detected and a preset voice frame detection model; performing framing processing on the input voice to obtain a plurality of voice frames with time sequences; sequentially inputting each voice frame of theinput voice into the voice frame detection model for detection, and outputting a first detection result corresponding to each voice frame; sequentially performing harmonic energy detection on each voice frame of the input voice to obtain a second detection result corresponding to each voice frame; determining a frame type corresponding to each voice frame based on the first detection result and the second detection result; and determining a voice starting endpoint and a voice ending endpoint of the input voice based on the frame type corresponding to each voice frame. The invention further discloses a voice endpoint detection device and equipment and a computer readable storage medium. According to the invention, the accuracy of voice endpoint detection is improved.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a voice endpoint detection method, device, equipment and storage medium. Background technique [0002] In the existing speech recognition technology, speech endpoint detection is often required, that is, to detect the start position and end position of the speech. At present, the speech endpoint detection algorithm is usually only suitable for speech and speech in relatively quiet scenes. This method is suitable for relatively stable noise. (such as white noise, siren sound, etc.), the effect is better, but the effect is poor for noisy environments (such as public places with many people talking). The reason is that the noise in such situations also has the characteristics of speech, so it is difficult to accurately Distinguishes noise from speech, resulting in poor speech recognition rates. Contents of the invention [0003] The main purpose of the present inv...
