Abstract

The invention provides a vehicle-mounted man-machine voice interaction system. The vehicle-mounted man-machine voice interaction system comprises a voice collection module, a voice purification module connected with the output end of the voice collection module, a voice processing method selection module connected with the output end of the voice purification module, a network module connected between the output end of the voice processing method selection module and the input end of a cloud server, a system terminal processor connected with the output end of the voice processing method selection module, the cloud server and a vehicle-mounted control unit module. The vehicle-mounted man-machine voice interaction system preferably selects the cloud server to carry out voice identification processing under the condition that wireless network signals are good in state in order to improve the accuracy and speed of voice identification, and can also start the system terminal processor when the wireless network signals are not good in order to keep normal work of the vehicle-mounted system.

Description

technical field [0001] The invention relates to the technical field of voice recognition, in particular to a vehicle-mounted man-machine voice interaction system, especially suitable for vehicle-mounted infotainment and information communication systems. Background technique [0002] With the rapid development of automotive electronics technology and people's demand for diversified, convenient, and humanized automotive functions, in-vehicle infotainment and information communication systems are gradually becoming hot spots pursued by automakers. In-vehicle infotainment and information communication systems mainly include in-vehicle communication systems, electronic navigation systems (GPS), intelligent transportation systems, in-vehicle networks, car audio systems, in-vehicle entertainment systems, etc. And the function of mobile office is not directly related to the safety and power performance of the car itself. [0003] Traditional in-vehicle systems often use push-butto...
