Abstract

Method for echo cancellation, echo cancellation device and electronic equipment, wherein the method includes: acquiring far-end signals and near-end signals generated by an electronic equipment during a phone conversation; performing linear filtering processing on far-end signals and near-end signals to obtain an initial error frequency spectrum; determining a current state of the electronic equipment based on far-end signals and near-end signals, the current state comprising a dual-talk state; determining a secondary filtering weight coefficient according to the current state; performing secondary filtering on far-end signals and near-end signals based on the secondary filtering weight coefficient and performing differential output to obtain a secondary differential frequency spectrum; comparing the initial error frequency spectrum with the secondary differential frequency spectrum to obtain a target output frequency spectrum.
