Speech recognition method, device, system, device and vehicle for vehicle

Abstract

The invention belongs to the field of vehicle technology, and specifically provides a voice recognition method, device, system, equipment and vehicle for vehicles, aiming to solve the problem that the existing technology cannot accurately recognize the voice of an interactive person when there is interference from other users' voices The problem. For this purpose, the voice recognition method for vehicles provided by the present invention includes detecting the location information of the user who wakes up the intelligent voice device in the vehicle; increasing the sound collection gain value of the directional radio equipment corresponding to the position information and reducing the radio reception of other directional radio equipment Gain value; the directional radio device after adjusting the radio gain value obtains the input voice information for waking up the user of the smart voice device and performs voice recognition according to the acquired voice information. Based on the above steps, the method provided by the present invention has the beneficial effect of reducing the interference of the voice of the user of the non-awakening smart voice device on the voice of the user of the wake-up smart voice device, and improving the accuracy of voice recognition in complex environments.
