intelligent vehicle voice denoising noise

With the application of speech recognition technology in the field of intelligent vehicle, it is becoming more and more mature , More drivers liberated their hands , Navigation can be carried out through simple voice instructions 、 Listen to the music 、 Control air conditioning, windows and other equipment .

Major technology giants have made great efforts in the vehicle voice assistant market , Voice interaction has become one of the important trends of human vehicle interaction .

GAC motor GS4 For example , GAC, which is connected to Tencent's eco car networking solution, can provide users with voice control navigation 、 entertainment 、 Vehicle control 、 System control 、 Encyclopedia of life, etc 47 An ecological service .

The vehicle connects Tencent's rich content service ecosystem , It can meet the content and service needs of users when navigating and driving .

Although the vehicle voice interaction, as the standard of new cars, has made great progress in recent years , But there are still many technical problems that can be improved and improved , For example, speech recognition that eliminates the influence of noise .

actually , Speech recognition in intelligent vehicle scene will be disturbed by all kinds of noise inside and outside the vehicle , Like the music in the car 、 Engine sound 、 Air conditioning sound , The wind outside the car 、 Vehicle sound, etc .

In order to shield the interference of noise on vehicle speech recognition , A number of AI Enterprises are committed to the development of training data and technology upgrading , Develop a vehicle voice system that can eliminate the influence of noise .

Even in the noisy environment inside and outside the car , The on-board voice system can also accurately recognize the user's voice instructions , Drivers don't have to because speech recognition is not enough “ smart ” And feel a headache .
