Abstract

A helmet with a voice-activated route guidance system includes a voice receiving unit for receiving a voice signal from a helmet user; a voice recognition unit for acquiring destination information of the user by analyzing the received voice signal; a positioning unit for searching a current position of the helmet user; a route setting unit for setting a route from the current position of the helmet user to a destination; a voice signal generation unit for generating a route guidance voice signal including information for guiding the helmet user to the set route; and a sound output unit for outputting the generated route guidance voice signal.

Claims

1. A helmet with a voice-activated route guidance system, in which the voice-activated route guidance system includes:

a voice receiving unit for receiving a voice signal from a helmet user;

a voice recognition unit for acquiring destination information of the user by analyzing the received voice signal;

a positioning unit for searching a current position of the helmet user;

a route setting unit for setting a route from the current position of the helmet user to a destination;

a voice signal generation unit for generating a route guidance voice signal including information for guiding the helmet user to the set route; and

a sound output unit for outputting the generated route guidance voice signal.

2. The helmet of claim 1, wherein the voice-activated route guidance system further includes a status display unit for generating and displaying information on functions performed by the voice-activated route guidance system.

3. The helmet of claim 1, wherein the positioning unit searches the current position of the helmet user by using a global positioning system (GPS).

4. The helmet of claim 1, wherein the voice receiving unit receives the voice signal through a dual microphone.

5. The helmet of claim 1, wherein the voice recognition unit recognizes a continuous voice included in the received voice signal and analyzes the received voice signal.

6. The helmet of claim 1, wherein the voice recognition unit analyzes the voice signal by using at least one of a speaker dependent voice recognition process and a speaker independent voice recognition process.

7. The helmet of claim 1, wherein the voice signal generation unit generates the route guidance voice signal by using a text-to-speech (TTS) technology.

8. The helmet of claim 1 further comprising:

a casing unit, which is positioned on a side of the helmet, including the voice-activated route guidance system.

9. The helmet of claim 8, wherein the casing unit includes:

one or more control buttons for generating a signal to control the voice-activated route guidance system;

a speaker for outputting the route guidance voice signal outputted from the sound output unit as sound; and

a wired input/output unit for receiving a voice signal of the helmet user,

wherein the control button is positioned on an outside of the helmet and the speaker is positioned on an inside of the helmet.

10. The helmet of claim 9, wherein the control button includes a button for selecting at least one of a voice-activated route guidance function, a short-range wireless communication function, and an audio source plying function.

11. The helmet of claim 1, wherein if the voice signal is not received from the helmet user, the voice signal generation unit generates a route guidance voice signal including information on the current position.

12. The helmet of claim 1, wherein the voice-activated route guidance system includes:

a communication unit for transmitting the received voice signal to an external communication terminal and for receiving a voice signal from the external communication terminal,

wherein the voice signal of the external communication terminal is outputted by the sound output unit.

13. The helmet of claim 12, wherein the communication unit receives and transmits the voice signal from and to the external communication terminal by using a Bluetooth system.

14. The helmet of claim 1, wherein the voice-activated route guidance system includes:

an audio source play unit for analyzing pre-stored audio source data and converting them into a sound signal,

wherein the sound signal is outputted by the sound output unit.
