The invention provides a power consumption control method, a mode configuration method, a VAD method, equipment and a storage medium. In the embodiment of the invention, the voice chip or equipment has a VAD function, whether a voice signal is input or not can be detected by utilizing the VAD function, and the voice chip or equipment enters a normal working mode from a low-power-consumption mode under the condition that the voice signal is detected, so that the power consumption of the voice chip or equipment can be saved; furthermore, the voice chip or equipment has a hardware VAD function and a software VAD function at the same time, various VAD modes can be generated by combining the hardware VAD function and the software VAD function, and by flexibly configuring the VAD modes used by the voice chip or equipment, the accuracy of a voice input detection result can be improved to a certain extent, the false triggering probability can be reduced, and the low power consumption performance of the voice chip or equipment is improved.
Description
technical field [0001] The present application relates to the technical field of voice processing, and in particular to a power consumption control, mode configuration and VAD method, device and storage medium. Background technique [0002] The low power consumption scheme of the traditional voice chip is mainly to build a hardware VAD (VoiceActivity Detection, that is, voice endpoint detection) module in the voice chip. The hardware VAD module detects whether there is a voice signal input based on the signal energy; when no voice signal input is detected, the voice chip is in a low power consumption mode; when a voice signal input is detected, the voice chip is woken up and starts voice processing. [0003] Since the hardware VAD module detects whether there is a voice signal input based on the signal energy, it is easy to be triggered by mistake in a noisy environment, resulting in poor low power consumption performance of the voice chip.
