Abstract

The embodiment of the invention provides a voice processing method and device and a vehicle. The method is applied to the vehicle, a plurality of voice areas are arranged in the vehicle, and each voice area is provided with at least one piece of audio acquisition equipment and at least one piece of audio playing equipment. The method comprises the steps of determining a target voice area where a target speaker is located in the vehicle; determining target audio data played by the audio playing equipment arranged in the target voice area; and based on the target audio data, performing noise reduction on the voice data acquired by the audio acquisition equipment, and extracting the voice data of the target speaker. According to the embodiment of the invention, in the scene that the vehicle is provided with a plurality of voice areas, when the audio playing equipment in a certain voice area plays an audio, the voice data acquired by the audio acquisition equipment in the voice area is subjected to effective noise reduction, and the user voice data with high cleanliness is extracted.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a voice processing method, device and vehicle. Background technique [0002] With the continuous improvement and development of the human-computer interaction function based on voice dialogue, the human-computer interaction function based on voice dialogue is gradually being applied to vehicles. Users in the car can control the vehicle to perform various operations through voice, such as adjusting seats, air conditioning, windows and rearview mirrors, etc.; or voice navigation, playing / pausing music, etc.; liberating the hands of users, especially the driver, Greatly improved user experience. [0003] One of the cores of the human-computer interaction function based on speech dialogue is speech recognition, and the accuracy of speech recognition depends on the front-end processing of speech information such as noise reduction. At present, the traditional voice noise reducti...
