No matter how good the touch experience of voice recognition technology is, it is unsafe for drivers to touch and operate the terminal system during driving. Therefore, voice recognition technology is particularly important, and it will be a booster for the development of the Internet of Vehicles. Mature voice technology allows drivers to issue orders to the Internet of Vehicles to request services through their mouths, and to receive services provided by the Internet of Vehicles with their ears. This is the most suitable application experience for cars, a fast-moving space. Mature speech recognition technology relies on a powerful corpus and computing power, so the development of vehicle speech technology itself has to rely on the network, because the storage capacity and computing power of the vehicle terminal cannot solve the speech recognition technology of non-fixed commands, but must It is necessary to adopt the “cloud recognition” technology based on server-side technology. Of course, technology is constantly evolving. In the development of the Internet of Vehicles, we will definitely encounter problems that have not been thought of until now, and new technologies and solutions will appear. We will wait and see what the Internet of Vehicles will be like in the future.
