Communication System and Method Between an On-Vehicle Voice Recognition System and an Off-Vehicle Voice Recognition System
First Claim
Patent Images
1. A computer based method in a vehicle, comprising:
- receiving a representation of first voice input;
performing a computer based voice recognition in the vehicle to the first voice input representation for generating a first voice recognition result;
determining a confidence value of the in-vehicle performed voice recognition process representing a likelihood that the first voice recognition result is correct;
determining that the voice recognition process to the first voice input representation should be performed external to the vehicle if the confidence value is lower than a first threshold; and
transmitting the first voice input representation to an external system in response to the determination that the voice recognition process should be performed external to the vehicle.

11. A system in a vehicle, comprising:
-
a microphone configured to receive a first voice input representation from a first user; a voice recognition location unit configured to determine whether a voice recognition process should be performed by a voice recognition system in the vehicle or external to the vehicle, the voice recognition system performing a computer based voice recognition in the vehicle to the first voice input for generating a first voice recognition result; a confidence value unit configured to determine a confidence value of the in-vehicle performed voice recognition process representing a likelihood that the first voice recognition result is correct; and a communications unit configured to transmit the first voice input representation to an external system in response to a determination that the voice recognition process should be performed external to the vehicle; wherein the determination is generated by the voice recognition location unit responsive to the confidence value being lower than a first threshold. - View Dependent Claims (12, 13, 14)

15. At least one non-transitory computer-readable storage medium having computer-executable instructions, the instructions when executed cause at least one processor to perform:
-
receiving a first voice input representation from a first user of the vehicle; performing computer based voice recognition to the first voice input representation in the vehicle for generating a first voice recognition result; determining a confidence value of the in-vehicle performed voice recognition process representing a likelihood that the first voice recognition result is correct; determining that the voice recognition process to the first voice input representation should be performed external to the vehicle if the confidence value is lower than a first threshold; and transmitting the first voice input representation to an external system in response to the determination that the voice recognition process should be performed external to the vehicle. - View Dependent Claims (16, 17, 18)
