The invention discloses an automobile voice command acquiring and processing system and method. A first denoising unit of the system conducts analog-digital conversion on a left channel sound signal and a right channel sound signal to obtain a left channel digital signal and a right channel digital signal. A second denoising unit conducts analog-digital conversion on a main channel sound signal to obtain a main channel digital signal. A signal processing unit conducts denoising on the main channel digital signal according to the left channel digital signal and the right channel digital signal to obtain a denoised digital signal. The second denoising unit further conducts denoising on the main channel sound signal according to a superposed signal of the left channel sound signal and the right channel sound signal and the denoised digital signal to obtain a denoised voice command. According to the automobile voice command acquiring and processing system and method, engine noise, outside noise and air-conditioning system and passenger seat noise can be filtered out effectively, the recognition rate of control commands of a driver is increased, and traveling security of automobiles is guaranteed.
Description
technical field [0001] The invention relates to the technical field of signal processing, in particular to a system and method for collecting and processing automobile voice commands. Background technique [0002] With the development of science and technology, the noise pollution in the cockpit of modern vehicles has become a topic of concern. How to minimize the noise pollution caused by engine operation, airflow and body friction, air-conditioning system, and co-pilot's voice in this relatively closed environment, so as to accurately identify the control commands issued by the driver, has become a research topic at home and abroad. hotspot. [0003] A traditional voice command acquisition and processing system includes a main microphone for picking up driver control commands (voice signals) and a signal processing module for processing the voice signal, and the signal processing module is used for filtering out noise signals in the voice signal. The defect of the above-...
