As shown in FIG. 1, the present invention includes a microphone 10 for collecting a driver's voice, and a voice recognition unit 12 for reading the other party's telephone number from the collected voice and generating and outputting a tone signal corresponding thereto. It is.

Here, the voice recognition unit 12 includes a head up display (HUD) 14 displaying a phone number input by voice, and a buffer 16 storing a phone number processed by the voice recognition unit 12. The speaker 18 which is connected and which wirelessly transmits the tone signal generated by the voice recognition unit 12 to the cellular phone 20 is coupled.

2 is a flowchart illustrating an operation state according to the present invention, which collects speech, extracts characteristics of the collected speech, and creates a speech pattern, and confirms a matching state between the reference speech pattern and the input speech pattern. If it is determined that the result of the second step and the result of the second step is the numeric tone, the corresponding number is displayed on the HUD 14 and the voice is input until the confirmation tone is input or a predetermined time elapses while waiting for input of the confirmation tone. If is not input, the number is stored in the buffer 16 and then waits for input of a new voice, otherwise the input number is not stored and waits for input of the next voice. Otherwise, the fourth step of confirming whether or not the input of the voice for notifying the correction and the input of the voice for notifying the result of the fourth step are deleted. A fifth step of waiting, a sixth step of confirming whether or not a sound for notifying a result of the fourth system is input of a voice for notifying transmission, and a call of the other party if not a voice input for notifying a result of the sixth step When a voice for reading a number is input, a seventh step of searching the phone book to read the phone number of the other party; and when a voice for notifying transmission is input, it is read out from the phone number or the phone book stored in the buffer 16. The eighth step of generating a tone signal corresponding to the telephone number and transmitting the signal wirelessly is shown.

The operation of the present invention configured as described above will be described.

First, when the voice collected by the microphone 10 is supplied to the voice recognition unit 12, the voice recognition unit 12 reads out a phone number corresponding to the collected voice and transmits the mobile phone 20 via the speaker 18. To transmit wirelessly. Therefore, the cellular phone can make a telephone call by forming a communication path with the telephone of the counterpart by the tone signal transmitted through the speaker 18.

The operation of the tone generator as described above will be described in more detail with reference to FIGS. 2A and 2B.

First, when the driver switches the power key of the mobile phone to the on state to make a call, the voice collected by the microphone 10 is supplied to the voice recognition unit 12, and the voice recognition unit 12 receives the input voice. The voice pattern is extracted and the feature is extracted and contrasted with the reference voice pattern stored in the memory (not shown) (S1). Here, the reference voice pattern stored in the memory refers to the voice pattern of the telephone number corresponding to each number of the other party's telephone number or the voice pattern of the specific telephone number for a specific voice, hereinafter referred to as a telephone directory.

If the voice inputted as a result of contrast (S2) is a numeric sound (for example, one, two, three ..... 0, etc.), the driver's voice of confirmation is displayed while displaying (S3) numerically on the HUD 14. Wait for input (S4).

Then, it is determined whether or not the voice is input, that is, non-voice (S5), and if it is non-voice, it is determined whether a predetermined time has elapsed (S6). Waiting for a new voice to be input while saving (S7), and also determining whether a confirmation voice has been input (S8), and in the case of the confirmation voice, storing the telephone number of the input number in the buffer 16 (S7) and inputting a new voice. If a voice other than the confirmation tone is input before a predetermined time elapses, the user waits for input of a new voice without storing the telephone number corresponding to the input number tone in the buffer 16.

If the input voice is not a numeric tone, the user determines whether it is a correction for deleting a previous wrong input (S9). If the input is corrected, the user deletes the previous input (S10). Done.

When the input voice is a voice of transmission, a tone signal corresponding to the telephone number corresponding to the telephone number stored in the buffer 16 or the telephone number read out from the telephone book is generated and carried through the speaker 18. Wireless transmission to the phone (S14) is made. In this case, the user must first press the transmission key of the cellular phone to transmit the tone signal transmitted through the speaker 18 to the base station through the cellular phone before saying the transmission.

However, if the voice is a voice for reading a specific phone number stored in the phone book rather than a voice called transmission, the phone number stored in the phone book is searched (S12) to read out the phone number (S13), and the new again. Waiting for voice input.

Accordingly, the mobile phone can open a phone call with the other party by a phone number transmitted wirelessly.

As described above, the present invention recognizes the driver's voice, reads the phone number of the corresponding party, converts it to a tone signal, and wirelessly transmits it to the mobile phone, thereby making a voice call without changing the mobile phone without a voice recognition function. Opening a road has the effect of making a phone call.

In particular, the present invention has the effect of safe operation by reducing the key operation of the mobile phone by inputting the phone number of the other party by voice when making a phone call using the mobile phone in the vehicle.
