Abstract

A combination of manual and voice input for a telematics system reduces visual distraction, works reliably, and is low cost. The telematics system uses a menu-based interface to communicate with the driver. This menu-based interface is accessible to the driver using both manual interactions and by voice. A reliable manual input mechanism is available using turn or push buttons in addition to voice recognition, which may not be accurate in all operating conditions. Voice recognition inputs can be limited to small numbers of words or phrases that can be more easily distinguished by a voice recognizer. Furthermore, voice outputs of the system are tailored to that they are readily recognizable to the driver. Manual input is optionally rejected in operating conditions in which such input is dangerous or prohibited.

Claims

1. A method for controlling a device using mixed manual and spoken input comprising:

prompting a user of the device using a combination of a visual prompt and an audible prompt, including

presenting a set of input choices,

accepting a command from the user to provide an audible prompt, and

in response to said command, playing an audible prompt that identifies one or more of the set of input choices; and

accepting an input from the user in response to the visual and audible prompts.

2. The method of claim 1 wherein presenting the set of input choices includes graphically presenting a list of the set of choices.

3. The method of claim 1 wherein presenting the set of input choices includes audibly presenting a list of the set of choices

4. The method of claim 1 wherein accepting the command from the user to provide an audible prompt includes accepting a manual command.

5. The method of claim 1 wherein accepting the command from the user to provide an audible prompt includes accepting a spoken command.

6. The method of claim 1 wherein playing the audible prompt includes playing an audible representation of the one or more of the choices.

7. The method of claim 6 wherein playing the audible representation of the choices includes playing a spoken description of the choices.

8. The method of claim 7 wherein playing the audible representation of the choices further includes applying a speech synthesis algorithm to produce the spoken description.

9. The method of claim 7 wherein playing the audible representation of the choices further includes accessing a stored audio representation of the spoken description.

10. The method of claim 7 wherein playing the audible representation of the choices further includes receiving data characterizing the spoken description from a remote location

11. The method of claim 1 wherein accepting the input in response to the visual and audible prompts includes accepting a manual input.

12. The method of claim 1 wherein accepting the input in response to the visual and audible prompts includes accepting a spoken input.

13. The method of claim 1 further comprising monitoring a condition of an environment of the device, and wherein accepting the input from the user includes limiting an input mode according to the environment.

14. The method of claim 13 wherein limiting the input mode includes rejecting manual input.

15. The method of claim 13 wherein limiting the input mode includes rejecting spoken input.

16. The method of claim 13 wherein the environment of the device includes a motor vehicle and monitoring the condition of the environment includes monitoring the speed of the vehicle.

17. The method of claim 14 wherein limiting the input mode includes rejecting manual input when the speed of the vehicle exceeds a threshold speed.

18. A mobile device comprising:

a user interface including, a graphical display, a manual input device, an audio output device, and an audio input device;

a controller coupled to the user interface configured to

prompt a user of the device using the graphical display and the audio output device, including displaying a visual prompt that identifies a set of input choices on the graphical display, accepting a command from the user to provide an audible prompt, and in response to said command, playing an audible prompt using the audio output device that identifies one or more of the set of input choices, and

accept an input from the user in response to the visual and audible prompts.
