Note that the communication unit 140 may communicate with the operation terminal 200 through wired communication.

Details of the control unit 110 will be described below with reference to FIG. FIG. 2 is a block diagram showing an example of the functional configuration of the control section 110. As shown in FIG.
The control unit 110 functionally includes a crying sound analysis unit 111 that is an example of an analysis unit, a crying factor determination unit 112 that is an example of a determination unit, a crying factor notification unit 113, a crying suppression sound generation unit 114, Crying suppression sound management means 115, crying suppression sound selection means 116 as an example of selection means, and crying suppression effect evaluation means 117 as an example of evaluation means are provided. These functions are realized, for example, by the CPU provided in the control unit 110 using the RAM as a work memory and appropriately executing various programs stored in the ROM.

The crying sound analysis means 111 analyzes the sound information acquired via the sound input section 120 .
For example, the crying sound analysis unit 111 analyzes the baby's crying sound input by the sound input unit 120, and extracts feature amounts. Specifically, the crying sound analysis means 111 performs spectral analysis and FFT (Fast Fourier Transform) processing on the crying sound to extract feature amounts.
More specifically, the crying sound analysis means 111 performs spectral analysis of the crying sound, thereby extracting feature quantities, for example, the duration of the crying sound, the stop time for breathing, and the like. In addition, the crying sound analysis means 111 performs FFT processing on the crying sound, and extracts feature quantities such as peak positions at 2 kHz or less, peak widths at 2 kHz or less, intensity at 2 kHz or more, differences from 2 kHz or less, and the like. .
It should be noted that the crying sound analysis means 111 may extract feature amounts not only for such sounds, but also for incidental information attached to the sounds.
For example, the crying sound analysis means 111 may analyze the time, elapsed time since the last breastfeeding or meal, place, temperature/humidity, or body temperature, and extract their feature values. Note that the location and temperature/humidity can be obtained by acquiring position information and temperature/humidity information from the operation terminal 200 through the communication unit 140, for example. Further, the body temperature can be obtained, for example, by acquiring body temperature information from a body temperature sensor that can communicate with the crying suppression device 100 .

Crying factor determination means 112 determines the crying factor according to the analysis result of the crying sound analysis means 111 . For example, the crying factor determining means 112 determines the crying factors based on the feature amount extracted by the crying sound analyzing means 111 .
Specifically, the crying factor determination means 112 determines the crying factor of the infant based on the feature amount extracted by the crying sound analysis means 111 and the values of the feature amount management table classified by crying factor as shown in FIG. . In other words, the crying factor determining means 112 determines the feature values of the crying sound extracted by the crying sound analyzing means 111 such as the onset time and stop time, the peak position at 2 kHz or less, the peak width at 2 kHz or less, the intensity at 2 kHz or more, A crying factor is determined by comparing the feature amount for the difference from 2 kHz or less with the values in the crying factor-specific feature amount management table of FIG.

The crying factor notifying means 113 notifies the parent of the crying factor by transmitting the result of the crying factor determination by the crying factor determining means 112 to the operation terminal 200 via the communication unit 140 . As will be described later, the parent of the operation terminal 200 can also input a crying factor different from the notified crying factor from the operating terminal 200 and correct it. In that case, the crying factor determining means 112 adopts the crying factor corrected by the guardian.

Crying suppression sound generating means 114 generates an utterance sound corresponding to the cause of crying as the crying suppression sound.
For example, the crying suppressing sound generating means 114 holds the mother's voice data sampled from the sound input unit 120, and processes the frequency, rhythm, and strength of the prescribed utterance phrase based on the mother's voice data, Generates speech for Motheries. Motheries, also called mother tongue, is a unique way of speaking when speaking to infants.

The crying suppression sound management means 115 manages the crying suppression sound containing the uttered voice generated by the crying suppression sound generation means 114 . For example, the crying suppressing sound management unit 115 manages crying suppressing sounds such as voice, noise, music, and life sounds in association with crying factors.
In addition, the crying suppression sound management means 115 selects at least one of the output frequency, the elapsed time from the last output, and the crying suppression effect for each crying suppression sound as a parameter that varies depending on the fatigue of the infant. Manage values. For example, when a crying suppression effect value is managed for each crying suppression sound, the crying suppression effect value is used by the crying suppression effect evaluation means 117, which will be described later, to evaluate the crying suppression effect of the crying suppression sound. will be updated accordingly.

The crying suppression sound selection means 116 selects a crying suppression sound corresponding to the crying factor from among the crying suppression sounds managed by the crying suppression sound management means 115 .
For example, the suppressing crying sound selection unit 116 selects suppressing crying sounds that the infant does not get tired of, from among the suppressing crying sounds corresponding to the crying factors determined by the crying factor determining unit 112 . As described above, the crying suppression sound management means 115 selects at least one of the output frequency, the elapsed time from the final output, and the crying suppression effect as a parameter that varies depending on the fatigue of the infant for each crying suppression sound. It manages the above values. Therefore, the suppressing crying sound selection means 116 selects the suppressing crying sounds that the infant does not get tired of, according to the parameter value, among the suppressing crying sounds corresponding to the crying factors determined by the crying factor determining means 112 . For example, when the value of the crying suppression effect is managed for each crying suppression sound, the crying suppression sound selection unit 116 selects the A crying suppression sound having the highest value of the crying suppression effect is selected.
The crying suppression sound selected by the crying suppression sound selection means 116 in this way is output from the sound output unit 130 to the infant.

The crying suppression effect evaluation means 117 evaluates the crying suppression sound based on the baby's voice picked up when the crying suppression sound is output.
As described above, the sound input unit 120 inputs the infant's voice even when the sound output unit 130 is outputting the crying suppressing sound. Therefore, the crying sound analysis means 111 analyzes the baby's voice when the crying suppression sound is output. For example, the crying sound analysis means 111 analyzes changes in volume, changes in frequency, etc., of the baby's voice.
Then, the crying suppression effect evaluation means 117 evaluates the crying suppression sound based on changes in volume, frequency, etc. analyzed by the crying sound analysis means 111 . When the above-described crying suppression sound managing means 115 manages the value of the crying suppression effect for each crying suppression sound, the crying suppression effect evaluation means 117 evaluates the corresponding crying suppression sound according to the evaluation. Updates the value of the crying suppression effect.

Returning to FIG. 1, the operation terminal 200 is a terminal used by a parent of an infant, such as a smart phone, tablet, or personal computer. The operating terminal 200 can communicate with the crying suppression device 100 , and can present information transmitted from the operating terminal 200 to the parent or set information input by the parent in the crying suppression device 100 . ing.
The operating terminal 200 includes, for example, a crying factor display section 210 and a crying factor input section 220 .

The crying factor display unit 210 is, for example, a liquid crystal display, and displays the crying factor determined by the crying suppression device 100 when the infant cries. In other words, by displaying the crying cause in the crying cause display section 210, the parent is notified of the reason why the infant is crying.

The crying factor input unit 220 is, for example, a touch panel, a keyboard, a mouse, etc., and acquires the correct crying factor input by the parent when the crying factor displayed on the crying factor display unit 210 is incorrect. . That is, the crying factor input unit 220 inputs the crying factor corrected by the parent.
The crying factors corrected from the crying factor input unit 220 are transmitted to the crying suppressing device 100 and used for learning the correspondence relationship between the feature values of the crying voice and the crying factors. For example, according to the corrected crying factor, the values of the crying factor-by-crying factor feature amount management table as shown in FIG. 3 are appropriately updated.

The operation of the crying suppression device 100 having such a configuration will be described below with reference to FIG. FIG. 4 is a flowchart for explaining an example of the crying suppression process executed by the crying suppression device 100 according to the first embodiment of the present invention.
Note that the crying suppression process shown in FIG. 4 is executed, for example, when a crying sound of an infant is input from the sound input unit 120 as a trigger.

First, the crying suppression device 100 estimates the cause of crying from the baby's crying sound (step S11).
That is, the crying sound analysis means 111 analyzes the baby's crying sound input by the sound input unit 120 and extracts a feature quantity. Specifically, the crying sound analysis means 111 performs spectral analysis of the crying sound to extract feature amounts for the duration of the crying sound, the stop time for breathing, and the like. Further, the crying sound analysis means 111 performs FFT processing on the crying sound, thereby extracting feature quantities such as the peak position at 2 kHz or less, the peak width at 2 kHz or less, the intensity at 2 kHz or more, the difference from 2 kHz or less, and the like.
Then, the crying factor determination means 112 determines the crying factors based on the feature amount extracted by the crying sound analysis means 111 . Specifically, the crying factor determination means 112 extracts the crying sound onset time, the stop time, etc. of the crying sound extracted by the crying sound analysis means 111, the peak position at 2 kHz or less, the peak width at 2 kHz or less, and the peak width at 2 kHz or more. The feature amount for the intensity at , the difference from 2 kHz or less, etc. is compared with the values in the crying factor-specific feature amount management table of FIG. 3 to determine the crying factor.

The crying suppression device 100 notifies the parent of the crying cause determined in step S11 (step S12).
That is, the crying factor notifying means 113 notifies the parent of the crying factor by transmitting the result of the crying factor determination by the crying factor determining means 112 to the operation terminal 200 via the communication unit 140 .

Crying suppression device 100 determines whether or not there is an instruction to correct the cause of crying (step S13).
In other words, the crying suppression device 100 determines whether or not the crying factor reported in step S12 has been corrected from the operating terminal 200. FIG.
When the crying suppression device 100 determines that there is no instruction to correct the crying factor (step S13; No), the process proceeds to step S15, which will be described later.

On the other hand, when it is determined that there is an instruction to correct the crying factor (step S13; Yes), the crying suppression device 100 corrects the crying factor (step S14).
That is, the crying factor determining means 112 adopts the crying factor modified by the parent. Then, the crying factor determining means 112 appropriately updates the values of the crying factor-by-crying factor feature quantity management table as shown in FIG. 3 described above in accordance with the corrected crying factor.

The crying suppression device 100 selects a crying suppression sound (step S15).
That is, the crying suppression sound selection means 116 selects the crying suppression sound corresponding to the crying factor from the crying suppression sounds managed by the crying suppression sound management means 115 . Specifically, the suppressing crying sound selecting means 116 selects suppressing crying sounds that the infant is not tired of, from among the suppressing crying sounds corresponding to the crying factors determined by the crying factor determining means 112 .
For example, when the value of the crying suppression effect is managed for each crying suppression sound, the crying suppression sound selection unit 116 selects the A crying suppression sound having the highest value of the crying suppression effect is selected.

The crying suppression device 100 outputs a crying suppression sound (step S16).
That is, the sound output unit 130 outputs the crying suppressing sound selected in step S15 to the infant.

Crying suppression device 100 analyzes the infant's voice (step S17).
That is, since the sound input unit 120 inputs the baby's voice even when the crying suppressing sound is output, the crying sound analysis unit 111 analyzes the baby's voice when the crying suppressing sound is output. For example, the crying sound analysis means 111 analyzes changes in volume, changes in frequency, etc., of the baby's voice.

The crying suppression device 100 evaluates the crying suppression effect (step S18).
That is, the crying suppression effect evaluation means 117 evaluates the crying suppression sound based on changes in volume, frequency, etc. analyzed by the crying sound analysis means 111 . For example, when the crying suppressing effect value is managed for each crying suppressing sound, the crying suppressing effect evaluation means 117 updates the crying suppressing effect value for the corresponding crying suppressing sound.

Through such a crying suppression process, the crying sound is analyzed and the cause of the crying is determined. Then, among the crying suppression sounds corresponding to the crying factors, the crying suppression sounds that the infant is not tired of are selected according to the parameters and output to the infant. As for the crying suppressing sound output to the infant, the crying suppressing effect is evaluated based on the infant's speech analysis, and the parameters are appropriately updated.

As a result, it is possible to appropriately suppress the infant's crying while avoiding a reduction in the effect due to boredom.

In the first embodiment, the case where the crying suppression device 100 communicates with the operation terminal 200 has been described. Crying suppression device 100 may be used alone after it has been updated to comply with .
