Abstract

The awakening method comprises the steps: judging whether the distance between a microphone array and a sound source point is greater than a preset distance or not; if yes, calculating calculation results of all preset wave beam directions in a microphone array on the current voice signal in parallel through a wave beam algorithm, wherein the microphone array is composed of a plurality of microphones evenly distributed on the same circular ring, and all the preset wave beam directions are all directions equally dividing the circumferential angle of the circular ring, and all the preset wave beam directions at least comprise four directions which are perpendicular to each other; according to calculation results of the current voice signals corresponding to the preset beam directions, calculating awakening probability values corresponding to the preset beam directions in parallel through an awakening algorithm; judging whether the wake-up probability value corresponding to each preset beam direction is greater than a first wake-up threshold value or not; if so, awakening according to the specified beam direction with the awakening probability greater than the first awakening threshold. Therefore, various defects caused by serial processing in the existing sound source positioning are avoided.

Description

technical field [0001] The present application relates to the computer field, in particular to a wake-up method, device and computer equipment. Background technique [0002] Most of the existing smart devices have a voice wake-up function. Generally, the microphone array is used to sort out the multi-channel voice signals first, and then the sound source is located, and then the sound processing such as beam noise reduction in the direction of the sound source is increased, and then the wake-up algorithm is processed and judged, which leads to the need to use the wake-up word and this voice signal to do it. For voice detection, it is necessary to use this voice signal for sound source localization, and then use this voice signal for beam noise reduction processing before waking up. A series of serial steps lead to the use of this voice signal, which will be buffered and processed in the system for a long time, and the sound source positioning will be erratic, which will aff...
