Abstract

The invention discloses a voice activity detection method. The voice activity detection method comprises the following steps: receiving voice data, wherein the voice data comprises a plurality of frames of voice signals; calculating the energy and spectral entropy of one frame of voice signals; carrying out square root calculation on the energy of the voice signals, or carrying out square root calculation on the spectrum entropy of the voice signals; calculating the spectral entropy energy root of the voice signals according to the energy after square root calculation or the spectral entropy after square root calculation; when the spectral entropy energy root of the voice signals is smaller than a first preset threshold value, judging that the voice signals are a non-voice frame; or when the spectral entropy energy root of the voice signals is not smaller than the first preset threshold value, judging that the voice signals are a voice frame. The invention further discloses a voice activity detection device and voice activity detection equipment, and the technical problem that in the prior part, for a scheme based on short-time energy and spectral entropy, the setting of the threshold value is greatly affected by a recording environment, or for a scheme based on spectral entropy energy product, the characteristics of the voice frame cannot be effectively reflected, consequently, a voice segment cannot be accurately detected, is solved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a voice activity detection method, a voice activity detection device and a voice activity detection device. Background technique [0002] Speech recognition is an interdisciplinary subject. In the past two decades, speech recognition technology has made remarkable progress and has begun to move from the laboratory to the market. With the development of speech recognition technology, speech recognition technology will enter various fields such as industry, home appliances, communications, automotive electronics, medical care, home services, and consumer electronics. [0003] Voice activity detection (Voice Activity Detection, VAD), also known as voice activity detection, voice endpoint detection, voice boundary detection, etc., is a technology used in voice processing to detect whether a voice signal exists. VAD is standard for voice recognition technology. [0004] In the prior art, t...
