Abstract

The present disclosure provides a voice interruption control method and device for an elevator, and the elevator. The method includes: acquiring a voice signal to be processed, the voice signal to be processed includes the user's voice control signal for the elevator and the elevator playing the first The echo signal of the speech signal; performing adaptive filtering on the speech signal to be processed based on the first speech signal to obtain a second speech signal; performing the speech signal to be processed, the first speech signal and the second speech signal The second speech signal is subjected to nonlinear processing to obtain an output result; and the elevator is interrupted based on the output result. The embodiments of the present disclosure can improve the success rate of voice interruption of the elevator.

Description

technical field [0001] The invention relates to the technical field of voice processing, in particular to a voice interruption control method and device for an elevator and an elevator. Background technique [0002] With the improvement of living standards, elevators are used more and more frequently, making people's lives more and more convenient. For elevators with voice interaction function, when users control the elevator through voice, they can collect voice signals through the microphone of the elevator, and control the elevator based on the collected voice signals. [0003] At present, when the elevator plays audio, video or news, the voice signal collected by the elevator's microphone may contain the sound played by the elevator's speaker. The sound played by the speaker may drown out the user's voice control signal to the elevator, resulting in the elevator's Interrupt success rate is low. Contents of the invention [0004] Embodiments of the present disclosure ...
