Abstract

The invention provides a far-field pickup equipment device and a method for acquiring a human voice signal in the far-field pickup equipment device. The far-field pickup system comprises an device equipment main body and a microphone pickup unit which are separated from each other. And tThe microphone pickup unit collects echoes of the user voice and the a sound signal played by the equipment devicemain body after spatial propagation and sends the echoes back to the device equipment main body for processing. Wherein tThe equipment device main body comprises a playing signal source; , a synchronization signal generator; , a horn; , a delay determination unit; and an echo cancellation unit. According to the embodiment of the invention, the problem that the microphone signal and the echo reference signal cannot be synchronized in the prior art can be solved, and the speech recognition performance is improved.

Description

technical field [0001] The present disclosure relates to the field of electronic equipment, and in particular to a far-field sound pickup device and a method for collecting human voice signals in the far-field sound pickup device. Background technique [0002] A smart speaker is a speaker that can recognize the voice command issued by the user during playback, such as "turn up the volume", and then act according to the user's voice command, such as "increase the volume of playback" . In these smart speakers, the microphone picks up sound signals in the environment, including user voice, interfering noise in the environment, and the echo of the sound signal played by the smart speaker. The sound signal collected by the microphone is converted into digital information and sent to the voice signal pre-processing module. The voice signal pre-processing module mainly has two tasks: first, use the echo cancellation algorithm to remove or reduce the echo of the sound signal playe...
