Abstract

The invention provides a voice activity detection method which comprises the following steps: acquiring a voice input signal; filtering the voice input signal to obtain a filtered voice signal; calculating a ratio of energy of the filtered voice signal to energy of the voice input signal; and comparing the ratio with a predefined threshold, and judging whether target voice activity exists according to the comparison result. According to the method, the energy of the filtered voice signal and the energy of the voice input signal can be calculated by virtue of time domain calculation only, and the complexity of frequency transformation and calculation in the frequency domain can be avoided, so that the calculation process and the complexity are simplified, and the operating power consumptionof equipment is reduced. In addition, with the adoption of a down-sampler in the filtering module, the overall realization complexity of the filtering module is obviously simplified. The invention further provides a corresponding voice activity detection device and a computer-readable storage medium.

Description

technical field [0001] The invention belongs to the field of voice activity detection, and in particular relates to a voice activity detection method and device and a computer-readable storage medium, which are used for detecting target voice activities, for example, for voice activity detection. Background technique [0002] With the popularization and development of intelligent electronic devices, many intelligent electronic devices integrate voice activity detection functions, such as voice activity detection functions, to detect human voice activities, and further improve the fun, convenience and practicality of human-computer interaction. In addition, in order to reduce the operating power consumption of electronic devices, especially portable electronic devices (considering the limited battery power on portable electronic devices), sound activity detection technology is also used to wake up and start the more power-consuming modules in the device , so that when the mod...
