Abstract

A voice-controlled navigation device includes a voice control unit, a display interface, a recognition unit, and a start unit. The voice control unit receives at least one voice command, the display interface displays a menu, and the recognition unit is used for recognizing the voice command for the display interface to display at least one option. The start unit executes a navigation function according to an corresponding option of one of the at least one voice command while receiving a specific voice start command. The menu displays one or a group of different options on the menu while a different voice command is received by the voice control unit, and each of the at least one voice command corresponds to one of the at least one option displayed on the menu.

Claims

1. A voice-controlled navigation device comprising:

a voice controlling means for receiving at least one voice command;

a display interfacing means for displaying in a first group of option in a first menu according to the voice command;

a recognizing means for recognizing a first keyword of the first group of options from the voice command and for outputting a second group of options to a second menu on said display interfacing means according to a recognition result of the first keyword, the second group of options being a subset of the first group of options; and

a starting means for executing a navigation function according to a second keyword of the second group of options after receiving a specific voice start command, each of the group of options being generated corresponding to the voice command and being displayed on the displaying interfacing means so as to allow users to directly read out contents or indicators of the option.

2. The voice-controlled navigation device of claim 1, being selected from the group consisting of a global positioning system, a mobile phone and a personal digital assistant.

3. The voice-controlled navigation device of claim 1, further comprising:

a storing means for storing a voice command database therein so as to enable said recognizing means to recognize the voice command.

4. The voice-controlled navigation device of claim 1, wherein said voice controlling means comprises a receiver.

5. The voice-controlled navigation device of claim 1, wherein said display interfacing means comprises a screen.

6. The voice-controlled navigation device of claim 1, wherein the recognizing means comprises a processor and an internal recognizing software suitable for recognizing the voice command.

7. The voice-controlled navigation device of claim 1, wherein the voice command is selected from a group consisting of a destination command, a dynamic position search command, and a personalized destination command.

8. The voice-controlled navigation device of claim 1, wherein when the voice command is a destination command, the menu displays at least one destination option and the option is at least one distance option, and the specific voice start command is then given to execute a navigation function corresponding to a selected distance option or to execute a cancel command.

9. A voice-controlled navigation method comprising:

receiving at least one voice command via a voice control unit;

displaying a first group of options in a first menu on a display interface according to the voice command;

recognizing a first keyword of the first group of options from the voice command;

outputting a second group of options to a second menu on the display interface according to a recognition result of the recognizing of the first keyword, the second group of options being a subset of the first group of options, each of the groups of options being generated corresponding to the voice command and displayed on the display interface so as to allow a user to directly read out contents of indicators of each of the options; and

executing a navigation function according to a second keyword of the second group of options by a start unit after receiving a specific voice start command.

10. The voice-controlled navigation method of claim 9, wherein the voice control unit is a receiver.

11. The voice-controlled navigation method of claim 9, wherein the display interface is a screen.

12. The voice-controlled navigation method of claim 9, wherein the step of recognizing comprising:

recognizing the voice command by processing the voice command by internal recognizing software.

13. The voice-controlled navigation method of claim 9, wherein the voice command is selected from a group consisting of a destination command, a dynamic position search command, and a personalized destination command.

14. The voice-controlled navigation method of claim 13, wherein when the voice command is a destination command, the menu displays at least one destination option and the option is at least one distance option, and the specific voice start command is then given to execute a navigation function corresponding to a selected distance option or to execute a cancel command.
