4 is a diagram illustrating a user interface portion required to perform a memory change / stop cancellation function of the call controller 100 of the voice recognition call apparatus for a vehicle according to an exemplary embodiment of the present invention.

As shown in Fig. 4, the call control unit 100 of the vehicular voice recognition call device according to the embodiment of the present invention includes: a reset switch 102 for initializing all functions; A voice password input switch 104 for inputting a voice password; A set switch 106 used to indicate that the voice password input is finished; A memory switch 108 for voice input of the shortcut and the corresponding telephone number; A stop request light indicator (110) displayed when the transmission / reception function is continuously stopped; And a stop switch 112 for turning off the stop request indicator 110 and turning it off so that transmission and reception can be started again.

In order to perform the memory change / stop release function, the memory change / stop release card 120 is required.

With the above configuration, the operation of the vehicular voice recognition call device according to the embodiment of the present invention is as follows.

First, in order to use the voice recognition call apparatus, the voice password must be stored. As shown in FIG. 5, the memory change / stop release card 120 is inserted into a card input unit (not shown) of the call control unit 100. (S41).

Then, the call control unit 100 is in a state capable of changing / stopping the memory.

The reset switch 102 is pressed in order to delete the voice password already stored in the call control unit 100 (S42).

Then, the voice password input switch 104 is pressed (S43), and the password is input by voice (S44).

At this time, up to three voice passwords can be entered. For example, drivers and assistants, fathers, sons and daughters-in-law can enter and remember passwords.

The set switch 106 is pressed to store the entered password (S45).

When the voice password memory is finished, the memory change / cancel release card 120 is removed (S46).

The following describes a case of calling outside using a voice recognition call device.

First, the user of the call device uses the power on / off switches 16, 26, and 36 to make the call device available (S1).

The power source can be applied to the call control unit 100 by the battery (BATT) of the vehicle by the ignition switch (IGSW), and is provided separately to the battery 90 to prepare for when the battery (BATT) is not connected.

At this time, resources of the call control unit 100 are initialized, and the number of errors is also initialized to zero.

Then, the transmission switch 12, 22, 32 installed in the driver's seat and the passenger seat and the rear seat (S2).

Then, the call control unit 100 outputs a voice message to input a password through the call unit 40, 50, 60, 70 (S3).

Then, the user speaks the password that he has already stored (S4).

The call controller 100 receives a voice password from the user and determines whether the voice matches one of the stored voice passwords (S5).

If the voice password does not match, the number of errors is increased by one (S6), and it is determined whether the number of increased errors is smaller than three (S7).

If the number of errors is less than 3, the voice password is repeatedly input from step S3.

If the number of errors is equal to or greater than 3, transmission is stopped (S15).

On the other hand, if the voice password matches, it is determined whether the voice of the password matches the voice of the voice password currently input (S8).

That is, to prevent someone else from using your password.

If the voice does not match, transmission is stopped (S15).

Now, since it is confirmed by receiving the voice password, the call control unit 100 outputs a voice message saying to input a phone number or a shortcut (S9).

Then, when the user knows the shortcut, the user speaks the shortcut, and when the user knows the telephone number, the user calls the telephone number.

Here, the abbreviation and the corresponding phone number should already be stored. The storing or changing the abbreviation and the corresponding phone number is shown in FIG. Plug in (S51).

Then, the memory switch 108 is pressed in order to store the abbreviation (S52), and the telephone number to be stored is first spoken (S53).

Then, the memory switch 108 is pressed again (S54), and a short word is input by voice (S55).

Finally, the memory change / stop cancellation card 120 is removed (S56).

When you know the shortcuts memorized in this way and make a call using the corresponding telephone number, you can make a call using the shortcut.

The call controller 100 receives a voice from the user (S10), and determines whether the input voice corresponds to one of the pre-stored short words (S11).

If it does not correspond to the abbreviated word, the input voice is recognized as a voice telephone number and the other party is called by sending a radio wave through the antenna 80 using the telephone number (S12).

If the abbreviation corresponds to the abbreviation, the call is made using the phone number indicated by the abbreviation (S13).

When the call is completed as described above and the other party is connected, the user can make a call (S14).

Next, when the transmission is stopped (S15), such as when the number of errors is three or more or the voices are inconsistent (S15), the call control unit 100 determines whether the suspension has occurred continuously (S16).

If the transmission is not interrupted continuously, a voice message of redialing is output and the user tries to transmit again (S17).

However, if the transmission is stopped continuously, it is treated as unable to continue to attempt transmission and lights up the stop release indicator 110 to inform the user that a continuous stop has occurred and indicate that this stop should be released. (S18).

Next, a case of receiving a call received from the outside using a voice recognition call apparatus will be described.

First, the power source is considered to be turned on (S21).

When the call radio wave is received from the outside through the antenna 80, the communication control unit 100 generates a reception sound through the communication unit 40, 50, 60, 70 to inform the caller user that there is a call from the outside ( S22).

The user selects and presses one of the reception switches 14, 24, and 34 to answer the call (S23).

Then, the call controller 100 outputs a voice message of inputting a password as voice (S24).

Then, the user speaks the password that he has already stored (S25).

The call control unit 100 receives a voice password from the user and determines whether the voice matches one of the stored voice passwords (S26).

If the voice passwords do not match, the number of errors is increased by one (S27), and it is determined whether the number of increased errors is one less than three (S28).

If the number of errors is less than 3, the voice password is repeatedly inputted from step S24 again.

If the number of errors is equal to 3 or greater than 3, reception is stopped (S31).

On the other hand, if the voice password matches, it is determined whether the voice of the password matches the voice of the voice password currently input (S29).

If the voice does not match, reception is stopped (S31).

If the voice is matched, the call is connected to the user from the outside to enable the call (S30).

Next, when the reception is stopped, such as the error count is three or more, or the voice is inconsistent (S31), the call control unit 100 determines whether or not this pause has occurred continuously (S32).

If the reception is not interrupted continuously, the voice message “Re-Receive” is output to allow the user to try again (S33).

However, if the reception was continuously stopped, it is treated as unable to continue to receive the reception and lights up the stop release indicator 110 to inform the user that a continuous stop has occurred and to indicate that this stop should be released. (S34).

7 is a flowchart illustrating a procedure of releasing stop when the stop releasing indicator 110 is turned on.

As shown in FIG. 7, first, the memory change / cancel release card 120 is inserted (S61).

Next, the stop release indicator 110 is turned off by pressing the stop release switch 112 (S62).

Then, the memory change / cancel release card 120 is removed (S63).

As described above, in the embodiment of the present invention, it is possible to transmit and receive by voice, and also to store the phone number as a short voice to prevent accidents without using a hand during a phone call, and has a voice confirmation function to use other people It is possible to provide a vehicular voice recognition call device and a method of controlling the same.
