If the predetermined voice command is received, the
Here, changing the output state means that the output of the voice guidance message is stopped based on the time point at which the voice command is pre-set, or the volume is gradually reduced in size.
Specifically, for example, when the
In this case, if the voice input is not detected for a predetermined time after the voice recognition function is activated, the
Meanwhile, in another example, when the output of the voice guidance message being outputted is stopped due to the reception of the predetermined voice command, the
In addition, the
Then, the
Here, the function corresponding to the recognized voice may include a function related to the next operation of the voice guidance message currently being output, or a function that is not related to the voice guidance message currently being output. For example, when the voice guidance message related to the map search is outputted, if the voice command irrelevant to the voice guidance message, for example, 'My Car, radio play' is inputted, the
Meanwhile, the
In this case, if the input voice of the driver is not related to the next operation of the voice guidance message currently being output, the
When the voice of the driver input through the
The
As described above, according to the vehicle terminal device according to the embodiment of the present invention, it is possible to control the terminal device by inputting a voice command without waiting for the driver to output the voice prompt until end, thereby contributing to user convenience.
In addition, in the present invention, a driver can input a voice command in a natural conversation form using a voice prompt.
In this regard, FIG. 4 is an example for explaining a method of inputting a voice command to the vehicle terminal device in a natural conversation mode, when the driver is interrupted at a desired time while the voice prompt is being output.
The
Referring to FIG. 4, for example, as the voice recognition function is activated, a voice prompt for inducing voice input of the driver through the voice output unit 152 (FIG. 2), 'Please, say the command' At the time of 'command' output, a voice command that instructs the driver to set the voice command and the next operation, for example, 'My Car! send a message to mom ', the
At this time, the echo cancellation technique may be applied to the voice prompt after the 'say' output time while the voice command predetermined by the driver is input. The echo cancellation technique suppresses an echo signal flowing in a transmission path in a direction opposite to that during transmission of a signal in one direction so as not to interfere with communication in order to eliminate a disorder caused by unnecessary echoing , A technique of instantly inserting a sufficient attenuation signal into the communication path to close the echo path.
For example, in FIG. 4, an interval A in which a first voice prompt (e.g., 'Please, the command') is output is a first interval (e.g., say the ') a1 and a second section (eg,' command ') a2. In addition, the driver's voice includes a third section (e.g., 'My Car') b1 corresponding to a preset voice command and a fourth section corresponding to a voice command related to the next operation (e.g., 'send a message to mom' ) < / RTI > (b2). Here, the echo cancellation technique described above may be applied to the second and third intervals. That is, the voice guidance message output in the second section gradually fades out while the volume is reduced.
If a voice command related to the next operation is recognized following the predetermined voice command, the
Meanwhile, if the predetermined voice command is received and the driver's voice is not input for a predetermined time, the
5A, 5B and 5C are views for explaining a method of outputting visual information related to a voice prompt to a screen according to an embodiment of the present invention. The
Specifically, when the predetermined voice command is received, the
In addition, when the voice guidance message is output, the
5B, when a voice command related to the next operation of the driver is input in the voice recognition mode, the
Thus, by informing the rest of the interrupted or faded out voice prompt through the screen, it is possible to provide understanding and convenience to the driver or the passenger.
6 is a flowchart illustrating a method of controlling a vehicle terminal apparatus according to another embodiment of the present invention. Here, there is shown an example in which the output state of the voice prompt is exceptionally handled when the output voice prompt is related to a situation requiring urgency.
Referring to FIG. 6, a step of outputting a voice guidance message related to the running of the vehicle based on a key input, voice input, or the like to the
Here, the situation requiring urgency may include situation information related to driving safety such as accident prevention of a vehicle, accident occurrence, emergency news, speed limitation, and the like, and status information set through user input, for example, have. Meanwhile, the
If it is determined that the output voice guidance message is related to a situation requiring urgency, the
Next, when the situation requiring urgency is canceled or the output of the voice guidance message is finished, the
Meanwhile, although not shown, if the voice command is received while the voice guidance message is being output and the voice of the driver is not input for a predetermined period of time, the
The
At this time, the
As described above, according to the vehicle terminal device according to the embodiment of the present invention, the user can control the terminal device by inputting a voice command without waiting for the driver to output the voice prompt until the end. In addition, the driver can activate a voice recognition function at a desired point by uttering a specific vocabulary, and can immediately perform the next operation by reducing or stopping the volume of the voice prompt being output, which is convenient for the user. Furthermore, it is possible to input a voice command by interrupting the output of the voice prompt, and by receiving feedback on the voice command again, it is possible to input voice commands in a natural conversation manner.
Further, according to the embodiment disclosed herein, the above-described method can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of the medium that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) . It should be noted that the vehicle terminal device and its control method described above can be applied to a configuration and a method of the embodiments described above in a limited manner, Some of which may be selectively combined.
