Command prefix for voice commands
View Patent ↗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.
1. 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.
2. The method of claim 1 , further comprising answering a call in response to the speech spoken by the user.
3. The method of claim 1 , further comprising generating a text message in response to the speech spoken by the user.
4. The method of claim 1 , further comprising generating a message to a recipient in response to the speech spoken by the user.
5. The method of claim 1 , further comprising generating a message to a recipient identified by the next spoken word.
6. The method of claim 1 , further comprising initiating a call in response to the speech spoken by the user.
7. The method of claim 1 , further comprising accessing a directory in response to the speech spoken by the user.
8. The method of claim 1 , further comprising retrieving a stored voice greeting in response to the speech spoken by the user.
9. 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;
comparing the next spoken word to electronic associations between vehicular commands and words including the next spoken word;
recognizing a vehicular command of the vehicular commands that is electronically associated with the next spoken word; and
executing the vehicular command in response to the speech spoken by the user.
10. The system of claim 9 , wherein the operations further comprise answering a call in response to the speech spoken by the user.
11. The system of claim 9 , wherein the operations further comprise generating a user interface that displays the vehicular command.
12. The system of claim 9 , wherein the operations further comprise answering a call in response to the next spoken word.
13. The system of claim 9 , wherein the operations further comprise generating a text message in response to the speech spoken by the user.
14. The system of claim 9 , wherein the operations further comprise generating a message to a recipient in response to the speech spoken by the user.
15. The system of claim 9 , wherein the operations further comprise generating a message to a recipient identified by the speech spoken by the user.
16. The system of claim 9 , wherein the operations further comprise initiating a call in response to the speech spoken by the user.
17. A memory device storing instructions that when executed cause a processor to perform operations, the operations comprising:
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;
retrieving a vehicular command of the vehicular commands that is electronically associated with the next spoken word; and
executing the vehicular command in response to the speech spoken by the user.
18. The memory device of claim 17 , wherein the operations further comprise answering a call in response to the speech spoken by the user.
19. The memory device of claim 17 , wherein the operations further comprise generating a text message in response to the speech spoken by the user.
20. The memory device of claim 17 , wherein the operations further comprise generating a message to a recipient in response to the speech spoken by the user.
