A method and device for collecting audio data

Abstract

The invention relates to an audio data collecting method and equipment used for reducing audio data which is missed during collection and increasing data integrity. The method includes: when a first trigger, a second trigger and a third trigger are used to detect audio signals and the fact that the energy of the audio signal detected by the first trigger is larger than or equal to the triggering threshold of the first trigger is determined, determining that the first trigger is triggered, wherein the triggering threshold of the first trigger is smaller than a first preset threshold; enabling the data channel of a storage so as to use the storage to collect the audio data input into an audio input system.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to an audio data collection method and device. Background technique [0002] At present, many devices support voice input, so an audio input system is generally set in the device. In order to reduce the power consumption of the system, the audio input system is in a dormant state before entering normal work or performing voice recognition, and needs to be woken up by voice. For example, if the energy of the input voice satisfies the trigger threshold of the trigger set for the audio input system, the trigger is triggered to open the data path of the first-in-first-out (First Input First Output, FIFO) memory to collect the input audio Data, and waking up the central processing unit (CPU), is equivalent to triggering the audio input system. [0003] That is to say, whether the audio input system can be triggered depends on the trigger threshold of the trigger. At present, ...

AI Technical Summary

Problems solved by technology

At present, the trigger threshold of the trigger is generally set higher. Then, before the trigger is triggered, no matter how much audio data is input to the audio input system, it cannot be collected because the audio input system is not triggered. of

[0004] It can be seen that the current solution will lead to missing audio data collection, resulting in incomplete data collection
