Classification: CPC G  H | IPC G  H

Claim 0:
1. A voice signal processing method, comprising:
acquiring a status coefficient, a target voice signal to be processed, and a derivative signal of the target voice signal;
using the derivative signal to respectively calculate an initial echo loss corresponding to each signal frame in the target voice signal, and using the status coefficient to adjust the initial echo loss to acquire a target echo loss;
using the derivative signal to calculate a proximal-distal coherence value of the target voice signal;
judging whether the target echo loss matches with a single-talk echo state;
if the target echo loss matches with a single-talk echo state, recording the proximal-distal coherence value in status statistical data, and updating statistical information;
using the statistical information to update the status coefficient, and performing volume control on the target voice signal when updating the status coefficient.
