Embodiments Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, and shows an example in which the remote control device of the present invention is applied to remote control of a television set.

Referring to FIG. 1, the present embodiment includes a wireless microphone 10 for inputting voice commands from a user and a television device 20. The television device 20 receives and demodulates a signal from the wireless microphone 10 to generate an audio signal. Audio signal receiving section 21 to be extracted and audio signal receiving section 2
A voice recognition section 22 executes voice recognition processing on the voice signal sent from the voice recognition section 1 and sends a control signal corresponding to the user's voice command to the television section 23, and according to the control signal sent from the voice recognition section 22. It is composed of a television section 23 that operates.

FIG. 2 shows an example of the contents of a table that maintains the correspondence between voice commands uttered by the user and control signals sent to the television section 23. The speech recognition unit 22 refers to such a table to obtain a control signal corresponding to the speech recognition result.

FIG. 3 shows an example of speech recognition processing performed by the speech recognition section 22 when using the speech command shown in FIG. 2, and this embodiment will be described in detail below with reference to each figure.

First, when operating the television device 20, the user speaks the desired action into the wireless microphone 10 using the voice command expression shown in FIG.

In the wireless microphone 10, the audio signal of the voice command uttered by the user is subjected to FM modulation or the like and transmitted to the outside, and in the television device 20, the signal from the wireless microphone 10 is received and demodulated by the audio signal receiving section 21. The audio signal is extracted and the audio recognition unit 22
sent to.

When the audio signal receiving unit 21 sends the audio signal to the audio recognition unit 22, the audio recognition unit 22 inputs the audio signal (step S1) and performs audio recognition (step S2), as shown in FIG. ).

Next, it is determined whether or not the recognition result recognized in step S2 is "power on" (step S3).
), if the power is on, the PSON signal is sent to the television unit 23 with reference to the table in FIG. 2 (step S4);
After that, the process returns to step S1 and waits for the next input.

When the recognition result is other than "power on", the process advances to step S5, and it is determined whether the recognition result is "power off".

Next, in step S5, the recognition result is “
When it is determined that the power is off, a PSOFF signal is sent to the television unit 23 with reference to the table in FIG. 2 (step S6).
, and then returns to step S1 to wait for the next input, otherwise proceeding to step S7.

Similarly, whether the recognition result of the audio signal is "channel X (X is 1 to 12)" (step S7), "volume high" (step S9), or "volume low" (step S
11) are sequentially determined, and with reference to the table in FIG. 2, if the recognition result is "channel , when the volume is "low", a VDN signal is sent to the television section 23 (step S12), and then the process returns to step S1 to wait for the next input.

If the recognition result does not correspond to any of the above, the process returns to step S1 and waits for the next audio signal to be input.

The television unit 23 operates according to the control signal sent from the voice recognition unit 22, and when the user turns on the power
When the PSON signal is sent from the voice recognition unit 22 by saying this, the power is turned on.

Similarly, if the user utters "power off", the television section 23 turns off the power; if the user utters "channel X", the television section 23 switches the channel to X, and utters "volume up". Then, the TV club 23 will raise the volume by one level,
If you say "low volume", the television section 23 will lower the volume by one level.

In this way, in this embodiment, since commands are given by voice, there is no need to operate complicated switches on the remote control unit (30, 50) as in the conventional example.
It is easy to handle.

Although this embodiment has described an example in which the remote control device of the present invention is applied to a television device, such a remote control device is not limited to a television device, but can also be applied to other devices such as a video deck or a television device. It can be used in a wide range of applications, such as operating large stage equipment.

[0027]

As explained above, the present invention has the effect that the operation is relatively simple and easy to understand because it is operated by voice.

[0028] Furthermore, since the receiving unit that receives audio signals from the wireless microphone and the voice recognition unit are built into the remotely controlled device, the user can remotely control the wireless microphone using only the wireless microphone, which makes it easy to use and eliminates the need for a place to place it. few.

Furthermore, since there is no need to point the wireless microphone at the device, there is the advantage that it can be operated even if there are obstacles as long as the output signal can reach the device.
