Abstract
Methods, systems, and products describe hands-free operation of automotive features. A user defines a command prefix that is recognized as preceding one or more voice commands. When the user speaks the command prefix, a processor identifies the spoken command prefix and treats a next spoken word as one of the voice commands. The voice command may then be executed for control.
Claims20
A method, comprising:
- receiving, at a processor operating in a vehicle, an audio signal generated from speech spoken by a user;
- recognizing, by the processor, a portion of the audio signal that corresponds to a command prefix, the command prefix representing a spoken word that indicates a next spoken word is a voice command;
- identifying, by the processor, another portion of the audio signal corresponding to the next spoken word after the command prefix;
- recognizing, by the processor, the next spoken word based on the another portion of the audio signal;
- comparing, by the processor, the next spoken word to electronic associations between commands and words including the next spoken word;
- recognizing, by the processor, the voice command of the commands that is electronically associated with the next spoken word;
- and
- executing, by the processor, the command in response to the speech spoken by the user.

A system, comprising:
- a processor;
- and
- a memory storing instructions that, when executed by the processor, cause the processor to perform operations, the operations comprising:
- receiving an audio signal generated from speech spoken by a user;
- recognizing a portion of the audio signal that corresponds to a command prefix, the command prefix representing a spoken word that indicates a next spoken work is a voice command;
- identifying another portion of the audio signal corresponding to the next spoken word after the command prefix;
- recognizing the next spoken word based on the another portion of the audio signal;

- receiving an audio signal generated by a microphone from speech spoken by a user;
- recognizing a portion of the audio signal that corresponds to a command prefix, the command prefix representing a spoken word that indicates a next spoken word is a voice command;
- identifying another portion of the audio signal corresponding to the next spoken word after the command prefix;
- recognizing the next spoken word based on the another portion of the audio signal;
- comparing the next spoken word to electronic associations between vehicular commands associated with a vehicle and words including the next spoken word;
