Problems solved by technology

The accuracy of offline speech recognition is low, only a few sentence patterns can be recognized, and the applicability is not high
The accuracy of online speech recognition is high, but the network performance of the vehicle scene is unstable, and weak network scenes are prone to appear. The efficiency of offline speech recognition in weak network scenes is not high, which affects the voice response speed of vehicle equipment.

Abstract

The invention discloses a voice processing method of vehicle-mounted equipment, and relates to a voice technology, an Internet of Vehicles technology and an intelligent vehicle technology in the fieldof artificial intelligence. According to the specific implementation scheme, the method comprises the steps of obtaining user voice; carrying out offline identification on the user voice to obtain anoffline identification text, and sending the user voice to a server to carry out online voice identification and semantic analysis on the user voice; if the text matched with the offline recognitiontext exists in the local text database, analyzing the offline recognition text to obtain an offline analysis result of the user voice; and controlling the vehicle-mounted equipment according to the offline analysis result. Therefore, the voice processing efficiency is improved while the voice processing accuracy of the vehicle-mounted equipment in a weak network scene is ensured. The invention further discloses a voice processing device of the vehicle-mounted equipment, equipment and a storage medium.

Description

technical field [0001] The present application relates to voice technology, Internet of Vehicles technology, and smart vehicle technology in the field of artificial intelligence, and in particular to a voice processing method, device, device, and storage medium for vehicle-mounted equipment. Background technique [0002] With the development of Internet of Things technology, smart vehicle technology, voice technology and other technologies, the intelligence of vehicle equipment is getting higher and higher, and even the function of voice assistant can be realized. When the vehicle-mounted device implements the function of the voice assistant, it recognizes the user's voice to perform some set operations, such as opening the car window, turning on the air conditioner in the car, and playing music. [0003] When the vehicle-mounted device recognizes the user's voice, it usually adopts offline voice recognition or online voice recognition. The accuracy of offline speech recogn...
