In this embodiment, droplets generated according to the utterance state of the singer S during singing are effectively collected.

Therefore, a predetermined utterance state related to voice is detected from the acoustic signals input to the microphones 43a and 43b, and the air purifier 3a is controlled based on the detection timing of the detected utterance state. Note that the predetermined utterance state related to speech is different from the content of utterance obtained by semantically analyzing the speech used for speech recognition, etc. is detected.

FIG. 6 is a flowchart showing music reproduction processing according to this embodiment. In the karaoke device 2, music is reserved based on the operation of the remote control device 1 or the input unit such as the touch panel monitor 33 or the like. When a song is reserved, reservation information including a song ID for identifying the song information, the user ID of the user who made the reservation, and the like is registered in a reservation table stored and managed in the memory 27 of the karaoke device 2 .

The karaoke machine 2 first checks the reservation table to confirm the music to be reproduced (S201). If there is a song to be played next (S202: Yes), song information corresponding to the song ID in the reservation information is read, and song playback is started (S203). In this embodiment, processing related to control of the air purifier 3a from S204 to S320 and scoring processing (S205) are executed.

The scoring process (S205) is a process of evaluating the singing ability of the singer S by comparing the singing voice input from the microphones 43a and 43b and the singing evaluation information included in the music information. Although not described in this embodiment, the scoring results obtained in the scoring process (S205) are notified to the singer S by display using the monitor 41 after the music reproduction process is finished.

On the other hand, during the reproduction period of the music, processing related to control of the air purifier 3a is performed by repeating S204 to S205. First, in this embodiment, an input voice analysis process (S204) is executed based on acoustic signals input to the microphones 43a and 43b used by the singer S. In this embodiment, it is a process of detecting the utterance state of the singer S, and in order to calculate the first parameter P1, detection of whether or not a specific sound (for example, plosive sound) is being uttered, and the second Volume detection in the speech is performed to calculate the parameter P2.

In the first parameter calculation process (S310), the first parameter P1 is calculated according to whether or not the specific sound obtained as a result of the input speech analysis process (S204) is uttered. FIG. 7 is a flowchart showing the first parameter calculation process of this embodiment. In the input speech analysis process (S204) of the present embodiment, utterance of a specific sound is detected as a predetermined utterance state. In this embodiment, plosive sounds (unvoiced [p][t][k], voiced [b][d][g]) are detected as specific sounds. Note that the specific sound may be not only a plosive sound but also a specific consonant sound.

If the specific sound is uttered (S311: Yes), the control transition count starts from 0 in the first parameter characteristic curve (S312). FIG. 8 is a diagram showing the first parameter characteristic curve of this embodiment. The first parameter characteristic curve of the present embodiment is a curve in which the horizontal axis is the control transition count (elapsed time [seconds]) and the vertical axis is the first parameter P1 (%). The first parameter P1 has an attenuation characteristic. In the present embodiment, the first parameter characteristic curve is used to calculate the first parameter P1. It is possible to adopt the form of

On the other hand, when the specific sound is not uttered (S311: No), the process of S312 is skipped. Next, when the control transition count is in progress (S313: Yes), the first parameter P1 is calculated according to the current control transition count (S314). For example, when the control transition count is 4 [seconds], the first parameter P1 is calculated as 70 [%].

After calculating the first parameter P1, control transition count up is executed (S315), and it is confirmed whether or not the control transition count has reached the upper limit (S316). When the control transition count reaches the upper limit (S316: Yes), the control transition count is stopped (S317). In this embodiment, the upper limit of the control transition count is set to 8 [seconds]. On the other hand, if the control transition counting is not in progress (S313: No), the calculation of the first parameter P1 is not performed, and the process ends.

Thus, in the first parameter calculation process (S310), the first parameter P1 is calculated at the timing when the specific sound is uttered, and used for controlling the air purifier 3a. Therefore, at the timing when the specific sound is uttered, it is possible to improve the cleaning ability of the air purifier 3a and effectively collect the droplets generated by the utterance of the specific sound.

Further, in this embodiment, the second parameter P2 based on the volume of speech is detected and used to control the air purifier 3a. FIG. 10 is a flowchart showing second parameter calculation processing according to this embodiment.

In the input speech analysis process (S204) of the present embodiment, the volume of the speech, that is, the volume of the speech in the acoustic signals input from the microphones 43a and 43b is also detected as the predetermined speech state. In the second parameter calculation process, a second parameter P2 for controlling the air purifier 3a is calculated based on the detected sound volume.

In the second parameter calculation process, first, as a result of the input voice analysis process (S204), it is determined whether or not the voice is uttered at a volume higher than a certain level (S321). If the voice is uttered at a certain volume or more (S321: Yes), control characteristics are set according to the volume. FIG. 10 is a diagram showing the second parameter characteristic curve of this embodiment. The second parameter characteristic curve of this embodiment is a plurality of curves with the control transition count (elapsed time [seconds]) on the horizontal axis and the second parameter P2 (%) on the vertical axis. control characteristics (first to fourth control characteristics).

Further, each of these control characteristics is such that the second parameter P2 attenuates as the control transition count progresses. In the present embodiment, the second parameter characteristic curve is used to calculate the second parameter P2, but instead of such a form, various forms of calculation such as using a table or calculating with a formula are used. can be adopted.

In S322, a control characteristic corresponding to the detected sound volume is set among the first to fourth control characteristics. As the sound volume increases, the second parameter P2 increases, and the air purification capacity of the air purifier 3a increases. Then, the control transition count starts from 0 (S323).

On the other hand, if the voice is not uttered at a certain volume or more (S321: No), the processes of S322 and S323 are skipped. Next, if the control transition is being counted (S324: Yes), the first parameter P1 is calculated according to the current control transition count (S314). This is done by reading the second parameter P2 corresponding to the current control transition count in terms of the control characteristics set in S322. For example, when the first control characteristic is set and the control transition count is 4 [seconds], the second parameter P2 is calculated as 30 [%].

After calculating the second parameter P2, control transition count up is executed (S326), and it is confirmed whether or not the control transition count has reached the upper limit (S327). In this embodiment, since there are four control characteristics, an upper limit value of the control transition count is provided for each control characteristic. When the control transition count reaches the upper limit (S327: Yes), the control transition count is stopped (S328). On the other hand, if the control transition is not being counted (S324: No), the calculation of the second parameter P2 is not performed, and the process ends.

As described above, in the second parameter calculation process (S320), the second parameter P2 is calculated at the timing when the sound volume increases, and is used for controlling the air purifier 3a. Therefore, it is possible to improve the cleaning ability of the air purifier 3a at the timing when the volume of the utterance increases, and to effectively collect the droplets generated by the utterance of the specific sound. In addition, it is also possible to change the cleaning ability of the air purifier 3a according to the volume of the speech, and perform adaptive control according to the speech.

FIG. 11 is a flowchart showing the device control process (S350) of this embodiment. In this embodiment, the control parameter Pall is calculated and transmitted to the air purifier 3a.

In the device control process (S350), first, the first parameter P1 and the second parameter P2 are compared (S351). be done. In this embodiment, the larger one of the first parameter P1 and the second parameter P2 is used as a base, and the smaller one is multiplied by 0.3 for auxiliary use (S352, S353).

After calculating the control parameter Pall, if the control parameter Pall is greater than its maximum value of 100[%] (S354: Yes), the control parameter Pall is corrected to 100[%] (S355). The control parameter Pall calculated in the above process is transmitted to the air purifier 3a using the infrared communication section 23 (S356). The air purifier 3 a receives the control parameter Pall through the infrared communication unit 36 and controls the blower fan 38 . On the other hand, when the control parameter Pall is equal to or less than the maximum value of 100[%] (S354: No), the control parameter Pall is transmitted to the air purifier 3a as it is using the infrared communication unit 23 (S356). .

As described above, according to the karaoke machine 2 of the present embodiment, by appropriately controlling the air conditioning device 3 such as the air purifier 3a according to the detected speech state, droplets are effectively collected and infection is prevented. It is possible to try to suppress it. Also, it is possible to suppress noise generated by the blower fan 38 of the air cleaner 3a. For example, when there is little or no speech, the noise generated by the air purifier 3a is suppressed to maintain a quiet situation.

[First modification]
Next, various modifications of this embodiment will be described. In the above embodiment, the karaoke machine 2 is used and the air cleaner 3a is controlled based on the acoustic signals input from the microphones 43a and 43b. Thus, the karaoke device 2 functions as a controller for the air purifier 3a (air conditioner 3). The present invention may be applied not only to the karaoke machine 2 but also to an air conditioning device controller (air conditioning device control device), which is a functional configuration for controlling the air purifier 3a in the karaoke machine 2 . The air conditioner controller detects a predetermined utterance state related to voice in the collected sound signal, and outputs a control instruction to the air conditioner based on the detection timing of the utterance state. At that time, the controller for the air conditioning device is not limited to the one that reproduces music like the karaoke device 2, and controls the air cleaning device 3 all the time or under predetermined conditions. good too.

Alternatively, it may be an air conditioning device control program that is installed in various information processing devices and implements the same functions as the air conditioning controller. For example, it is possible to install it in a mobile terminal such as a smart phone and control air conditioners placed around based on acoustic signals collected by the smart phone.

Further, the air conditioning device controller may be installed in the air conditioning device 3 such as the air purifier 3a. FIG. 12 is a diagram showing an air purifier 3a of another embodiment, in which an air conditioner controller is mounted. The air cleaner 3a is provided with a microphone 39 for collecting ambient sounds. The control unit 37 detects a predetermined utterance state related to voice from the sound signal collected by the microphone 39, and the instruction processing is performed based on the detection timing of the predetermined utterance state detected by the voice detection processing. perform control over

In this way, by mounting the air conditioning device controller in the air purifier 3a, it is possible to execute control related to air conditioning according to the speech state. Such an air purifier 3a is, for example, a desktop air purifier 3a installed on a desk, and is effective in collecting droplets of a user positioned around the desk.

[Second modification]
In the above-described embodiment, as the air conditioning device 3, the control is performed targeting the air purifier 3a installed in the room. The air conditioner 3 to be controlled is not limited to the air purifier 3a, and may be the air conditioner 3b or the ventilation fan 3c as described with reference to FIG. Further, the control target is not limited to one air conditioning device 3, and a plurality of air conditioning devices 3 may be controlled simultaneously. At that time, by providing device control information for each air conditioning device 3 of different types, it becomes possible to perform control suitable for the air conditioning device 3 .

[Third Modification]
In the above-described embodiment, the first parameter P1 is calculated based on the utterance of the specific sound (plosive sound), the second parameter P2 is calculated based on the volume of the utterance, and the two parameters are used to determine the air purifier 3a. is controlling As described above, in the above-described embodiment, the air purifier 3a is controlled based on two types of utterance states, that is, the utterance of the specific sound and the volume of the utterance. good too.

Also, the first parameter P1 uses one first parameter characteristic curve as described in FIG. 8, but the characteristic for calculating the first parameter P1 is may be changed according to For example, by increasing the control value for a plosive sound that tends to generate a lot of splashes and decreasing the control value for other consonants, it is possible to perform adaptive control according to the type of uttered consonant.

[Fourth Modification]
In the above-described embodiment, the infrared communication system is used for controlling the air purifier 3a. Communication between the karaoke device 2 and the air purifier 3a (air conditioner 3) is not limited to the infrared communication method. For example, a wired communication method such as a USB cable or a wired LAN may be used. Alternatively, a wireless communication method such as a wireless LAN or Bluetooth (registered trademark) may be used.

Further, in the above-described embodiment, the infrared communication section 23 of the karaoke device 2 transmits the device control information to the air purifier 3a. In a room such as a karaoke box, the karaoke device 2 may be installed under hidden conditions such as under a rack or sofa. Under such circumstances, it is conceivable that the air purifier 3a will be in the blind spot from the karaoke machine 2 and infrared communication will not be possible.

Therefore, communication may be performed via the remote control device 1 between the karaoke device 2 and the air purifier 3a (air conditioning device 3). For example, when the karaoke device 2 and the remote control device 1 are connected for communication using a wireless LAN, the device control information is transmitted from the karaoke device 2 to the remote control device 1 using the wireless LAN. The communication unit 19 is used to transmit the device control information to the air purifier 3a. Since the remote control device 1 is often placed on a table or the like where the line of sight is good, it is possible to perform good infrared communication with the air purifier 3a. It should be noted that the karaoke machine 2, the remote control device 1, and the air purifier 3a (air conditioning device 3) can be appropriately communicated with each other.

Although the karaoke device 2 of the present embodiment has been described above, the present invention is not limited to the karaoke device, and the remote control device 1, a smartphone owned by the user, a personal computer installed at home, or a game machine , etc., also belong to the scope of the present invention.
