Abstract

A system and method for providing voice prompts that identify task selections from a list of task selections in a vehicle, where the user employs an input device, such as a scroll wheel, to activate a particular task and where the speed of the voice prompt increases and decreases depending on how fast the user rotates the scroll wheel.

Claims

1. A voice-based menu navigation system comprising:

a speech engine operable to recite a list of choices to a user for the user to choose from;

an input device that is operated by the user and is operable to increase or decrease the speed of the recitation of the list of choices in response to operation by the user, wherein the recitation of the list of choices becomes an abbreviated description for faster navigation; and

a component that is operable to track the manipulation speed of the input device provided by the user and set a default rate of speed based on a user'"'"'s tracking history.

2. The system according to claim 1 wherein the speech engine is a text-to-speech engine that recites the list of choices from text data.

3. The system according to claim 2 wherein the text-to-speech engine chooses which text to process and recite to the user based on the user'"'"'s manipulation of the input device if there are two or more text descriptions for each choice in the list of choices.

4. The system according to claim 1 wherein the speech engine is an audio file player, said list of choices being based on audio files provided by the audio file player, wherein manipulation of the input device changes the speed of the playback of the audio file player.

5. The system according to claim 4 wherein there are two or more audio files for each choice in the list of choices, and wherein the speech engine chooses which audio file to recite to the user based on the user'"'"'s manipulation of the input device.

6. The system according to claim 1 wherein the speech engine is operable to recite the list of choices in forward or reverse order and with varying speed, wherein the list of choices is recited at a speed in reverse order that is faster than a preceding forward speed.

7. The system according to claim 1 wherein the speech engine determines a command the user speaks and recites a list of commands the user may have intended, and wherein the user uses the input device to select the desired command.

8. The system according to claim 1 wherein the speech engine determines the list of choices to be recited based on the content of a text file with markup tags where the markup tags describe which content applies to which speed of recitation of the list of choices.

9. The system according to claim 8 wherein the markup tags differentiate between audio files that are used for slow recitation and audio files that are used for fast recitation.

10. The system according to claim 8 wherein the markup tags differentiate between text descriptions that are used for slow recitation and text descriptions that are used for fast recitation.

11. The system according to claim 8 wherein the markup tags tell the speech engine whether to use text descriptions or audio files for recitation of the list of choices.

12. The system according to claim 1 wherein the list of choices includes advertisements.

13. The system according to claim 12 wherein the input device is operable to allow the user to select an advertisement to get more information about the advertisement.

14. A voice based menu navigation system comprising a terminal component and a network component where the terminal component connects to the network component through a voice channel and a data channel and the network component is operable to recite a list of choices to a user over the voice channel that allows the user to choose a choice through a voice response from the terminal component over the voice channel or through data signals sent from an input device on the terminal component to the network component, wherein the terminal component is operable to track the manipulation speed of the input device provided by the user and set a default rate of speed based on a user'"'"'s tracking history.

15. The system according to claim 14 wherein the input device is operable to allow the user to control the speed of recitation of the list of choices.

16. The system according to claim 14 wherein the input device is operable to cause a speech engine to recite the list of choices both forwards and backwards.

17. The system according to claim 14 wherein the input device is operable to allow the user to change the order of the list of choices.
