Abstract

The invention provides an elevator voice interruption control method and device and an elevator. The method comprises the steps of obtaining a to-be-processed voice signal, wherein the to-be-processedvoice signal comprises a voice control signal of a user for the elevator and an echo signal of a first voice signal played by the elevator, performing adaptive filtering processing on the to-be-processed voice signal based on the first voice signal to obtain a second voice signal, performing nonlinear processing on the to-be-processed voice signal, the first voice signal and the second voice signal to obtain an output result, and conducting voice interruption on the elevator based on the output result. The embodiment of the invention can improve the voice interruption success rate 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.
