A processor of a vehicle speech recognition system recognizes speech via domain-specific language and acoustic models. The processor further, in response to the acoustic model having a confidence score for recognized speech falling within a predetermined range defined relative to a confidence score for the domain-specific language model, recognizes speech via the acoustic model only.

Acoustic and domain based speech recognition for vehicles

An automatic speech recognition system for a vehicle includes a controller configured to select an acoustic model from a library of acoustic models based on ambient noise in a cabin of the vehicle and operating parameters of the vehicle. The controller is further configured to apply the selected acoustic model to noisy speech to improve recognition of the speech.

Voice control is extended outside of an automotive vehicle by an access system associated with a door and window. An accelerometer is mounted on the window to generate a vibration signal. A passive entry system generates an unlock standby signal when an authorized user carrying a wireless fob is detected proximate the door. A voice recognizer in the vehicle is activated by the standby signal to scan the vibration signal for a spoken command for opening the door. A door actuator is activated by the voice recognizer when the command is detected.
