Voice recognition method, device and system for vehicle, equipment and vehicle

Abstract

The invention belongs to the technical field of vehicles, and particularly provides a voice recognition method, device and system for a vehicle, equipment and the vehicle, aiming at solving the problem that the voice of an interactive person cannot be accurately recognized under the condition of voice interference of other users in the prior art. For this purpose, the voice recognition method forthe vehicle includes detecting position information for a user who wakes up intelligent voice equipment in the vehicle; increasing the radio gain value of directional radio equipment corresponding tothe position information and reducing the radio gain value of other directional radio equipment; and acquiring input voice information for the user who wakes up the intelligent voice equipment throughthe directional radio equipment after adjustment of the radio gain value and preforming voice recognition according to the acquired voice information. Based on the above steps, the method has the advantages of reducing the voice interference of users who do not wake up the intelligent voice equipment on users who wake up the intelligent voice equipment and improving the voice recognition accuracyrate in a complex environment.
