Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an internal configuration diagram of an applied vehicle terminal of the present invention.

The present invention provides a GPS receiver 140 for receiving information on the location of a vehicle through a satellite, a CDMA radio unit 110 which is a mobile communication terminal attached to a vehicle with a unique device number, and a user's operation command. An input unit 180 for inputting, a memory 120 storing a plurality of names and corresponding telephone numbers, a voice recognition unit 150 for recognizing a voice and converting the voice into a text, and a voice signal from the text The voice synthesizer 160 outputs the voice dialing command via the voice synthesizer 160, the display unit 170 on which the street name or map is output, and the voice recognition unit, and sends the call to the corresponding phone number. The voice synthesizer outputs a question asking whether the name corresponding to the telephone number is correct through the voice synthesis unit, and recognizes the response from the other party through the voice recognition unit. It consists of a control unit 100 for connecting the call.

At this time, the voice dialing command commands the name of the other party to be called, and the controller 100 converts the input name into text data through the voice recognition unit 150 and then corresponds to the corresponding name in the memory 120. Search for a phone number and call the phone number. Alternatively, using the voice dialing command as a phone number, the control unit 100 converts the input phone number into text data through the voice recognition unit 150 and then sends the corresponding phone number.

Although not shown in the drawing, the input unit 180 may include a button for calling a specific person. When the controller 100 detects that the button is pressed through the input unit 180, the controller 100 sends a call to the phone number stored in the memory 120.

The voice is synthesized and output through the voice synthesizer 160, and the response from the counterpart is recognized through the voice recognizer 150 to connect the call to the user in the case of affirmative.

2 is a flowchart illustrating a call connection process in the vehicle information terminal of the present invention.

The user enters a dialing command (step 210) to make a call with the other party, wherein the dialing command is configured in the form of a voice, and the user dials the name of the other party to call or dials the phone number of the party to call. You can make a dialing command.

In order to talk to the other party, the user inputs a dialing command by voice. When a dialing command is input by voice (step 210), the telephone number of the person corresponding to the voice command is dialed (step 220). Here, depending on whether the other party responds (step 230), when the other party answers (YES in step 230), the other party checks the other party by synthesizing a voice to confirm whether the other party originally intended to talk. 240). For example, suppose that the name used when the user dialed is "Hong Gil Dong". When the other party responds, the command "Hong Gil Dong" used when the original dialing command was made through the voice synthesis unit and "who" "Who is it?" Synthesized the stored voice, and the voice synthesis "Hong Gil-dong?" The other person will hear the answer, either yes or no, such as "yes" or "no". In other words, whether or not the other party was originally intended to talk through the positive or negative intention to check. The voice recognition unit recognizes this, and if the other party wants to talk, the other party asks whether the other party is willing to talk to the user, and asks the other party in the form of "Who do you want to talk to?" desirable. If the other party reveals the positive or negative intention of the call, after confirming the other party's intention to talk (step 250), the call is connected only when the other party has expressed the positive intention (step 260).

3 is a flowchart illustrating a process of performing voice dialing using the name of the other party.

The driver inputs a dialing command in the name of the other party to be talked with by voice (step 310). That is, when the driver is driving or stopping, if the name of the other party to call "Hong Gil-dong" is input, the vehicle terminal recognizes this voice and dials the person "Hong Gil-dong" (step 320). When the receiver answers the call (step 330), the dialing command "Hong Gil Dong" and the fixed voice "Who are you?" Are combined with the voice "Hong Gil Dong?" (Step 340). At this time, the receiver responds with affirmative or negative answers such as "yes" or "no" to tell the user whether he or she is "Hong Gil Dong". The speech recognition unit recognizes a positive or negative answer (step 350), and if the user determines that the person to whom the call is intended is the same person as the person to whom the call is answered, the voice recognition part asks the intention of the call (step 360). . In this case, it is desirable to ask the recipient by voice, "Who do you want to talk to?"

Here, the receiver reveals the driver's intention of positive or negative to the driver, and the voice recognition unit recognizes it. If the recipient has indicated an affirmative intention that the caller is willing to call, it is desirable to connect the call (step 360) and present a voice message to the user and the recipient before the call.

If the recipient has indicated that he or she is unwilling to call, he will not make a call to the other party, but will send a voice message to the user, such as "The other party does not want to talk." It is desirable to indicate that you do not want.

4 is a flowchart illustrating a process of performing voice dialing using a telephone number.

When the driver inputs the voice dialing command as a phone number (step 410), the vehicle information terminal searches for a name corresponding to the entered phone number, outputs it (step 420), and dials the name (step 410). 430). After dialing, when the receiver answers the call (step 330), as in FIG. 3, the voice is sent to the receiver through voice synthesis (step 440). The recipient identifies his or her identity by answering a positive or negative answer, such as "yes" or "no," and the voice recognition unit recognizes it (step 450), and then whether the user was originally trying to make a call. Will be judged.

If the recipient is determined to be the same person as the name of the person he / she is trying to call, the recipient is asked to speak (step 460), which is also asked to ask the recipient a question such as "Do you want to call?" It is preferable.

If the called party announces the positive or negative intention to the driver, the vehicle terminal recognizes it, and if the called party indicates the positive intention that the receiver is willing to call, the call is connected (step 470), and "Call" Voice message to the user is desirable. In addition, if the recipient has indicated that he or she is not willing to talk, he will not connect the call, and the user will be notified that the recipient does not want to talk to the driver. It is desirable to inform.

In another embodiment of the present invention, instead of performing voice dialing with the name and phone number of the other party, the user registers the name and phone number of the party to be called in a specific button in advance, and the user presses the specific button. Dial the party you want to talk to.

For example, suppose a user has saved a person's name "Hong Gil-dong" and a person's phone number "011-123-4567" in a particular button "1". If the user presses the button "1", Dial the registered telephone number " 011-123-4567 " and convert the registered name " Hong Gil-dong " into voice to confirm the identity of the other party through voice synthesis. That is, in the same manner as in FIGS. 3 and 4, when the converted voice of "Hong Gil Dong" is synthesized with the fixed voice and the question "Are you Hong Gil Dong?" To the other party, the other party reveals a positive or negative answer. The other party then confirms the identity.

When the other party's identity is verified, the receiver is asked whether he / she is willing to talk to the user through voice synthesis. If the answer from the other party is affirmative, the call is connected to the user. If the answer is negative, the call is not connected.

Although the present invention has been described with some examples. The invention is not limited to the specific embodiments. Those skilled in the art will appreciate that various modifications and changes can be made without departing from the spirit of the invention.

As described above, according to the present invention, when the vehicle information terminal attempts to make a call connection with the other party, when the other party's voice is dialed in a voice or text form and dialed, it is determined whether the other party is the original party through voice synthesis. By recognizing the voice of the other party and checking the intention of the call, the call is connected to prevent the hassle of checking the person who wants to talk to each other while the driver is driving. It is effective in preventing one's eyes from disturbing safe operation.
