AI Technical Summary

Technical Problem

Existing speech processing methods cannot effectively filter out noise in speech data, especially in noisy environments.

Method used

By generating the filter coefficient before receiving the wake-up word at the terminal, the received voice data is filtered to ensure that the filter coefficient is not affected by the wake-up word pronunciation, thereby effectively filtering out noise.

Benefits of technology

It realizes effective filtering of voice data in a noisy environment, improving the accuracy of speech recognition and the effectiveness of filtering.

Abstract

The embodiments of the present application disclose a voice processing method, device, equipment and storage medium. The method includes: receiving first voice data, the first voice data is received after the terminal switches from the standby state to the working state, and includes voice data of instruction information; based on the first filter coefficient generated by the terminal at the first moment, the first voice data is filtered to obtain the voice data of the instruction information, the first moment is the moment before the wake-up word is received, and the wake-up word is used to instruct the terminal to switch from the standby state to the working state. The method provided in the embodiments of the present application can effectively filter out noise in the voice data.
