Abstract

The invention provides a mobile phone interconnection-based vehicle-mounted speech recognition system and recognition method. With the mobile phone interconnection-based vehicle-mounted speech recognition system and recognition method adopted, recognition rate and recognition speed can be ensured, and a problem of much occupation of the memory of a vehicle-mounted terminal by network resources of speech recognition can be solved. The system includes a microphone, a vehicle-mounted terminal which sends speech information to a mobile phone end and receives speech recognition result of the mobile phone end or a cloud speech recognition engine, the mobile phone end which analyzes and recognizes the speech information through mobile phone application software so as to obtain the speech recognition result of the mobile phone end, sends the speech information to the cloud speech recognition engine, receives the speech recognition result of the cloud speech recognition engine, performs arbitration on the speech recognition result of the mobile phone end and the speech recognition result of the cloud speech recognition engine through mobile phone application software, and sends the speech recognition result of the mobile phone end or the cloud speech recognition engine to the vehicle-mounted terminal according to an arbitration result, and the cloud speech recognition engine which analyzes and recognizes the speech information and sends the speech recognition result to the mobile phone end.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a vehicle-mounted voice recognition system and a recognition method based on mobile phone interconnection. Background technique [0002] With the rapid development of the field of automotive electronics, especially the enrichment and complexity of the functions of the vehicle information and entertainment system, the traditional operation method is increasing the degree of driving distraction, driving safety is constantly being threatened by various .
