Abstract

The method and system of the invention increase the convenience of making a call on a portable phone and improve the safety of making the call while driving a vehicle. The system includes a communication module for wireless voice and character data transmission between the hands-free system and the portable phone and provides for voice command driven use of the portable phone without requiring a physical connection. The method provides for registering the entries on the portable phone into the system and for placing a call on the portable phone using the system.

Claims

1. A hands-free system for a portable phone, the system comprising:

a voice recognition module for receiving a name and recognizing it;

a memory for storing at least one telephone number and at least one name;

a voice synthesizing module, wherein said voice synthesizing module outputs a name according to an instruction of said voice recognition module;

a microprocessor for controlling said hands-free system based on signals received from said memory and said voice recognition module;

an I/O module for inputting or displaying a telephone number of said portable phone; and

a communication module for transmitting voice and character data through wireless communication, wherein said hands-free system allows a user to place a phone call using voice commands, and said hands-free system outputs information through said voice synthesizing module based on input name, telephone number, and character information.

2. The hands-free system of claim 1, wherein said I/O module comprises:

an interface module communicates with a vehicle;

an LCD display module for displaying said telephone number of said portable phone; and

a key input module for inputting said telephone number of said portable phone to said memory.

3. The hands-free system of claim 1, wherein said system detects portable phones and displays telephone numbers of said detected portable phones on said I/O module.

4. The hands-free system of claim 1, further comprising an amplification module connected to the voice synthesizing module to amplify the voice and output it through a speaker.

5. The hands-free system of claim 1, wherein said portable phone comprises a built-in module for communicating with said communication module.

6. The hands-free system of claim 1, wherein said portable phone is equipped with an adapter for communicating with said communication module.

7. The hands-free system of claim 1, wherein during the output of the voice, an audio system of a vehicle is muted.

8. The hands-free system of claim 1, wherein said voice synthesizing module outputs a voice according to character information displayed on said portable phone.

9. A hands-free system for a portable phone, comprising:

a microprocessor programmed to provide voice command driven use of the portable phone;

a communication module configured to detect the presence of at least one portable phone and to facilitate the wireless exchange of information between the microprocessor and the at least one portable phone;

a voice recognition module configured to;

receive a data packet representing a spoken word from the microprocessor;

create a second data packet representing said spoken word using signals from a microphone;

determine whether the first and second data packets match; and

output the result of whether the first and second data packets match to the microprocessor;

a memory for storing the data packets and the information;

a voice synthesizing module configured to translate the data packets and the information into signals that upon conversion into sound are understood to be spoken words;

an amplifier and speaker for converting said data packets and the information into sound;

a user interface; and

an input/output module configured to;

relay input from the user interface to the microprocessor; and

relay output from the microprocessor to the user interface;

wherein said hands-free system automatically recognizes the presence of at least one portable telephone, interfaces with the at least one portable telephone, and allows the operation of the at least one portable telephone through voice commands through the microphone and input from the user interface.

10. The hands-free system for a portable phone of claim 9, further comprising a vehicle interface, and wherein said input/output module is further configured to relay commands from the microprocessor to the vehicle through the vehicle interface.

11. A method for operating a hands-free system to allow a user make a call using a portable phone, comprising:

having the hands-free system automatically recognize the presence of at least one portable phone;

wirelessly interfacing the hands-free system with the at least one portable phone;

transferring information from the at least one portable phone to the hands free system, wherein the hands-free system receives at least one data packet with a corresponding phone number from said at least one portable phone;

constructing voice commands for the hands-free system that are specific for the at least one portable phone recognized, the constructing comprising;

prompting a user to repeat a spoken name, wherein the spoken name was generated using a data packet;

creating a second data packet representing the repeated spoken name using signals from a microphone;

determining whether the first and second data packets match; and

storing the first and second data packets as names if they match; and

operating in response to commands input by the user to the hands-free system, said operating comprising;

responding to voice commands from the user; and

responding to commands input by the user through a keypad.

12. The method of claim 11, further comprising relaying commands from the hands-free system to the vehicle through a vehicle interface.
