Airborne radio voice recognition control method and system

Abstract

The invention provides an airborne radio voice recognition control method and system. The method comprises the following steps of extracting radio voice data from remote radio voice received by an airborne radio; carrying out enhanced denoising preprocessing on the radio station voice data; voiceprint authentication recognition and voice content recognition being carried out on the preprocessed radio station voice data; when the voice data of the radio station is judged to be from a speaker with command authority through voiceprint authentication recognition, voice text content obtained through voice content recognition being synthesized into electronic voice, and the voice text content being converted into a machine language instruction to be temporarily stored; the electronic sound being outputted to an airborne radio station to be fed back to a cab operator; and transmitting the machine language instruction to the airborne flight control system for execution in response to a confirmation signal made by the operator according to the electronic sound. The method is advantaged in that voice instruction transmission, recognition and character conversion are carried out in an airborne radio station environment, pure electronic sounds are synthesized, so an operator can confirm the instruction and make an execution decision, and an instruction presentation mode is simplified.

Description

technical field [0001] The invention relates to the field of airborne control and voice technology, in particular to an airborne radio voice recognition control method and system. Background technique [0002] The intelligent control method of aircraft has been paid more and more attention by countries all over the world. Research on the realization of intelligent voice command control system technology on the embedded platform can simplify its operation process and hide operation details. For the airborne voice control in the radio environment, the current voice technology system has poor adaptability and poor real-time performance; and the current control and interaction methods are relatively cumbersome to implement, and the expression methods are relatively complicated, which can no longer meet the needs of current operations. At the same time, in real operation, the radio environment is in a high-noise environment, and the existing voice technology encounters great diff...
