摘要
An echo time delay detection method, an echo elimination device, and terminal equipment are provided. The echo time delay detection method includes: obtaining an audio signal transmitted through air and acquired by an audio input device of terminal equipment when detecting a call access request, the audio signal corresponding to an audio output by an audio output device of the terminal equipment; converting the audio signal to obtain a signal to be processed; determining a reference signal corresponding to the audio signal; and determining an echo time delay value according to the reference signal and the signal to be processed.
