<Outline of the operation of the reproduction system 1>
FIG. 3 is a diagram showing an example of a schematic operation of the reproduction system 1.
First, the user A who owns the terminal device 30 creates transmission information (1A). The transmission information is electronic information used when exchanging information between the terminal device 30 and the mobile terminal 20. The transmission information is, for example, voice or text information, which will be described in detail later. The user A creates a message to the user B who owns the mobile terminal 20 by voice or text. The user A and the user B are predetermined persons and have a predetermined friendship relationship. For example, a parent-child relationship or a friend relationship.

The voice information can be created by the user A speaking to the terminal device 30, and at this time, the voice is acquired by the microphone 302 and recorded. Specifically, the user A turns his / her face to a position facing the terminal device 30, for example. Then, when the user A presses the record button 305a of the operation buttons 305, the microphone 302 records only while the user presses the record button 305a. If you want to stop recording, you can release your hand from the record button 305a. Then, the user A speaks the content he wants to convey to the user B with his own voice while pressing the record button 305a. Information on the recorded voice is stored in the memory of the control unit 306.
Further, the text information may be input from a keyboard or the like connected to the terminal device 30, but, for example, the display 304 may be a touch panel and the touch panel may be used for input. Furthermore, as described above, a method of inputting voice and recognizing the voice to convert it into text may be used.

Then, the control unit 306 transmits the voice and text information as transmission information to the mobile terminal 20. The transmission information is sent to the mobile terminal 20 via the communication antenna 301, the access point 90, and the network 70 (1B).
In the mobile terminal 20, a dedicated application for realizing the reproduction system 1 is operating, and the communication I / F acquires this transmission information. The CPU stores this transmission information in the memory (1C). At this time, the mobile terminal 20 may be provided with a light emitting source such as an LED, and the light emitting source may be blinked or the like to notify the user B that the transmission information has arrived from the user A. Further, the guidance that the transmission information has arrived from the user A may be output as a ring tone or a voice.

  User B can reproduce the transmission information. Specifically, the user B presses a play button or the like on the input mechanism such as the touch panel of the mobile terminal 20. As a result, the voice transmitted from the user A is read from the memory and output from the speaker (1D). Thereby, the user B can hear the message transmitted from the user A. When the transmission information is text information, the text can be displayed on a display mechanism such as a touch panel.

  Then, the user B creates transmission information for replying to the user A (1E). The method of creating the transmission information is the same as the method described in the case of the user A described above.

Then, the CPU of the mobile terminal 20 transmits the voice information as transmission information to the terminal device 30 (1F). The transmission information is sent to the terminal device 30 via the communication I / F, the access point 90, and the network 70.
In the terminal device 30, the communication antenna 301 receives this transmission information, the control unit 306 acquires it, and stores it in the memory (1G). By the operation of the user A, the transmission information sent from the user B is read from the memory and reproduced (1H).
Then, the same operation is repeated thereafter. That is, the transmission information is exchanged between the user A and the user B.

  Next, a detailed functional configuration and operation of the reproduction system 1 according to the present embodiment will be described.

<Description of functional configuration of playback system 1>
FIG. 4 is a block diagram showing a functional configuration example of the reproduction system 1.
Here, among various functions of the reproduction system 1, those relevant to the present embodiment are selected and shown.
In the reproduction system 1, the mobile terminal 20 includes a transmission / reception unit 21 that transmits / receives information, a display unit 22 that displays images, an input unit 23 that inputs information, and an audio output unit 24 that outputs audio. .

The input unit 23 is an input mechanism for inputting text, voice, and the like, and is, for example, the above-described touch panel, input button / keyboard, or the like. The input unit 23 is an input mechanism that inputs the voice of the user B, and is, for example, a microphone.
The audio output unit 24 is a speaker that outputs audio.

  The terminal device 30 transmits / receives transmission information, a transmission / reception unit 31, a storage unit 32 that stores transmission information, an acquisition unit 33 that acquires voice, a reproduction unit 34 that reproduces voice, and displays an image. Display unit 35, grasping unit 36 for grasping the characteristic information of the person performing the reproduction operation, setting unit 37 for determining the voice quality of voice, operation unit 38 for accepting the operation of user A, and change for changing the voice quality of voice. It includes a unit 39 and a reproduction control unit 40 that controls reproduction of sound.

  The transmission / reception unit 31 receives the transmission information from the user B who owns the mobile terminal 20. Further, the transmission / reception unit 31 transmits the transmission information from the user A to the user B. The transmission / reception unit 31 is, for example, a communication I / F and is included in the control unit 306. The communication antenna 301 is also included in this. The transmission / reception unit 31 transmits / receives transmission information between the terminal device 30 and the mobile terminal 20 via the access point 90 and the network 70.

  The storage unit 32 stores the received transmission information. The storage unit 32 also outputs this when necessary. The storage unit 32 is, for example, a memory, a HDD (Hard Disk Drive), an SSD (Solid State Drive), or the like, and is included in the control unit 306.

The acquisition unit 33 is an example of an acquisition unit, and acquires a sound such as the voice of the user A. The acquisition unit 33 corresponds to the microphone 302. As the type of microphone, various existing types such as a dynamic type and a condenser type may be used. Further, the microphone is preferably a non-directional MEMS (Micro Electro Mechanical Systems) type microphone.
The reproducing unit 34 is an example of a reproducing unit, and reproduces voice as the transmission information transmitted from the user B. The reproduction unit 34 corresponds to the speaker 303 that reproduces sound.
The display unit 35 is also an example of a reproducing unit, and reproduces the text as the transmission information transmitted from the user B. The display unit 35 is, for example, a touch panel as described above. In this case, the display unit 35 includes a display that displays various kinds of information and a position detection sheet that detects a position touched by a finger, a stylus pen, or the like. As a means for detecting the contacted position, any method such as a resistance film method that detects based on pressure due to contact or a capacitance method that detects based on static electricity of the contacted object is used. Good.

The grasping unit 36 is an example of grasping means, and grasps characteristic information of a person who performs a reproducing operation for reproducing on the reproducing unit 34 or the display unit 35. In this case, the person who performs the reproduction operation is the user A and the listener of the voice of the user B. Here, the "feature information" is information that characterizes the speaking style of the user A who is the listener. The characteristic information is, for example, the age of the user A. Since the words used differ depending on the age, the age is information that characterizes the way the user A speaks. The characteristic information is, for example, the gender of the user A. Gender is information that characterizes the way the user A speaks, because the words used differ depending on the gender. Further, the characteristic information is, for example, the residence area of the user A. Depending on the residential area, the language used is a standard language or a dialect used in the residential area. Therefore, the residential area is information that characterizes the way the user A speaks.

For example, the setting unit 37 sets the voice quality of the voice reproduced by the reproducing unit 34 according to the user A who is the listener. This setting can be determined based on the characteristic information of the user A grasped by the grasping unit 36. Alternatively, the user A may determine the settings by himself / herself and input them to the terminal device 30. This can be performed, for example, by operating the operation unit 38 described below.

<Explanation of the operation of the reproduction system 1>
Next, the operation of the reproduction system 1 of the present embodiment will be described in more detail.
FIG. 5 is a flowchart illustrating an example of the operation of the reproduction system 1 of this embodiment.
First, the user A operates the operation unit 38 of the terminal device 30 and uses the acquisition unit 33 to record a voice (step 101). The voice information is stored in the storage unit 32 as transmission information (step 102). Further, the transmission / reception unit 31 directs the transmission information to the mobile terminal 20 and transmits it (step 103). The transmission information may include information on the date and time when the transmission information was created.

On the other hand, in the terminal device 30, the grasping unit 36 grasps the characteristic information of the user A based on the voice acquired by the acquiring unit 33 (step 104).
Hereinafter, a method for estimating the age of the user A, the gender of the user A, and the residential area of the user A as the characteristic information will be described.

(Estimation of age of user A)
FIG. 6 is a diagram showing an example of a method of estimating the age of the user A.
FIG. 6 shows a frequency spectrum of voice. Here, the horizontal axis represents frequency and the vertical axis represents spectrum intensity. That is, the frequency spectrum shows the relationship between the frequency and the intensity of the frequency component contained in the voice.
Here, regarding voice, an example of frequency spectra of persons aged 40, 50, 60, and 70 is shown. As shown in the figure, it can be seen that the spectrum intensity at 4 kHz or higher increases as the age increases. Actually, the increase in the spectrum intensity of 4 kHz or more causes the voice to become a hoarse voice that makes the voice more audible.
Therefore, the grasping unit 36 can estimate the age of the user A by looking at the spectrum intensity of 4 kHz or higher in the frequency spectrum.

(Estimation of Gender of User A)
7A to 7C are diagrams showing an example of a method of estimating the gender of the user A.
The audio signal shown in FIG. 7A can be divided into two, the fundamental frequency shown in FIG. 7B and the aperiodic component shown in FIG. 7C. The fundamental frequency represents the pitch of a voice. For example, the fundamental frequency of male voice is 100 Hz to 200 Hz, and the fundamental frequency of female voice is 250 Hz to 500 Hz. The aperiodic component represents a voice color. Therefore, the gender of the user A can be estimated from the fundamental frequency.

(Estimation of the residential area of user A)
In this case, the position of the terminal device 30 can be obtained by adding a GPS (Global Positioning System) function to the grasping unit 36, and thus the residence area of the user A can be estimated. Further, instead of the GPS function or in combination with the GPS function, the position of the terminal device 30 may be obtained using the position information of the Wi-Fi access point.

Returning to FIG. 5, in the terminal device 30, the setting unit 37 determines the setting of the transmission information to be reproduced by the reproducing unit 34 based on the characteristic information. (Step 105).
FIG. 8 is a diagram showing the characteristic information and the method of changing the setting.
FIG. 8 is a table summarizing the contents set by the setting unit 37 when the grasping unit 36 estimates the age of the user A, the gender of the user A, and the residential area of the user A as the characteristic information.
First, when the transmission information is set according to the age of the user A as the characteristic information, the voice quality of the voice can be changed according to the user A. When the age of the user A is a young person such as a minor or an infant, for example, the voice quality of the voice is changed to a parent voice, a mechanical synthetic voice, or the like. In the case of an infant, when using the voice of the parent, a sense of security can be obtained. Further, in the case of children, there is a research result that the mechanical voice is easier to follow the saying than the parent's voice. Therefore, the voice quality may be changed to the mechanical voice. Also, the wording of the voice may be changed according to the user A. For example, the audio wording may be changed from the usual “-please.” To a command tone such as “-please.”. Further, in the case of a young person, the text may be faster and easier to understand than the voice, so that the transmission information may be converted from the voice to the text.

  On the other hand, when the age of the user A is an elderly person, such as 60 years or older, the wording of voice may be converted into a polite language. For example, change "Welcome back." To "Welcome back." Also, words that are difficult for the elderly to understand, such as young people's words, may be converted into words that are easy for the elderly to understand. Furthermore, in the case of an elderly person, it may be easier to understand the content of the transmission information with voice than with text, so the transmission information may be converted from text to voice.

  When the transmission information is set according to the gender of the user A as the characteristic information, the wording of the voice can be changed according to the user A. For example, according to the gender of the user A, if the user A is male, the female word may be converted into a male word, and if the user A is female, the male word may be converted into a female word. .

  Furthermore, when the transmission information is set as the characteristic information according to the residence area of the user A, the voice language can be converted into the dialect used in the area where the user A resides. For example, the voice sent from the user B to the user A can be converted from a standard language into a dialect or from a dialect into a standard language.

  The feature information described above can be set only by acquiring voice once, but the setting is not limited to this. That is, a method may be used in which the voice is acquired a plurality of times and the setting is sequentially changed by this. As a result, the setting accuracy can be further improved. For example, in order to set the parent's voice, a voice library can be created by acquiring the voice of the target person multiple times, thereby making it possible to make the voice closer to the voice quality of the target person. .

  Further, since the characteristic information is set by the acquired voice, this setting is not performed, for example, when transmitting information is created only by text. In this case, for example, the terminal device 30 may notify that the setting is not made by voice guidance or the like, and may prompt the user to input a voice for performing the setting.

  Returning to FIG. 5 again, the transmission information transmitted from the terminal device 30 is transmitted to the mobile terminal 20 via the access point 90 and the network 70. In the mobile terminal 20, the transmission / reception unit 21 acquires the transmission information (step 106). Then, the CPU of the mobile terminal 20 stores this transmission information in the memory (step 107).

  On the other hand, the user B presses the play button or the like from the dedicated application in the input mechanism such as the display unit 22 and the input unit 23 of the mobile terminal 20. As a result, the voice transmitted from the user A is reproduced by the speaker, which is the voice output unit 24 of the mobile terminal 20 (step 108).

  Then, the user B creates transmission information for replying to the user A (step 109). The method of creating the transmission information is the same as the method described above for the user A, and is performed by recording the voice of the user B using the microphone corresponding to the input unit 23. The recorded voice is stored in the memory (step 110). At this time, the transmission information can be created in text using the input unit 23.

Then, the transmission / reception unit 21 of the mobile terminal 20 transmits this transmission information to the terminal device 30 (step 111). The transmission information is sent to the terminal device 30 via the transmission / reception unit 21 of the mobile terminal 20, the access point 90, and the network 70.
In the terminal device 30, the transmission / reception unit 31 receives the transmission information (step 112). Then, the transmitted transmission information is stored in the storage unit 32 (step 113).

  Further, in the terminal device 30, the user A operates the operation unit 38, and the reproduction unit 34 reproduces the transmission information returned from the user B. At this time, the reproduction control unit 40 controls the reproduction of the transmission information. At this time, the transmission information is converted by the changing unit 39 according to the setting determined by the setting unit 37, and the converted transmission information is reproduced (step 114). That is, the voice quality and wording are changed. Further, at this time, the changing unit 39 may change the text, the human voice, and the mechanical synthetic voice to each other depending on the setting.

The changing unit 39 changes the wording, for example, when the wording before conversion and the wording after conversion are registered in advance as the wording to be converted, and the wording before conversion appears by voice recognition. Then, replace this part with the translated wording.
Further, in order to convert voice into text, the changing unit 39 performs voice recognition of voice and converts it into text. Furthermore, in order to convert text into speech, a method of performing speech synthesis based on text can be used.
Then, in order for the changing unit 39 to convert the voice quality, for example, the voice is first divided into the fundamental frequency and the aperiodic component as described in FIG. 7. In addition, the voice signal is Fourier transformed to obtain the frequency spectrum, and the spectrum envelope is extracted from this. The spectral envelope is the logarithm of the frequency spectrum further Fourier-transformed, so to speak, a spectrum of the spectrum.

FIG. 9 is a diagram showing an example of the spectrum envelope.
In FIG. 9, the horizontal axis represents frequency and the vertical axis represents spectrum intensity. In the figure, the line represented by Ss is the frequency spectrum. On the other hand, the line represented by Sh is the spectrum envelope. The spectrum envelope Sh represents a gentle variation of the frequency spectrum Ss, and is a fine variation (spectral fine structure) of the frequency spectrum Ss separated from the frequency spectrum Ss. The spectral envelope Sh represents the characteristic of the human vocal tract. Therefore, the spectral envelope Sh of a different vocal tract can be reproduced by converting this spectral envelope Sh. That is, the voice quality can be different from the original one. In addition, the pitch of the voice can be changed by changing the fundamental frequency to a different frequency. Furthermore, changing the magnitude of the aperiodic component also changes the voice quality. For example, the smaller the aperiodic component, the smaller the blurring of the voice, and the larger the non-periodic component, the larger the blurring of the voice. Then, by resynthesizing the converted waveform, the voice quality can be changed.

  The changing unit 39 may also perform frequency conversion of voice. In other words, elderly people often hear the low-pitched sound and the mid-pitched sound, but are hard to hear the high-pitched sound. Therefore, the high-frequency range sound is frequency-converted into the mid-range frequency range so that the sound can be heard even if the sound includes the high-frequency range sound.

10A and 10B are diagrams showing frequency conversion of voice.
Here, the horizontal axis represents frequency and the vertical axis represents sound pressure.
Of these, FIG. 10A shows the case where frequency compression is performed as frequency conversion of voice. In this case, the waveform of the voice shown by the solid line is compressed in the high frequency range of 4000 Hz or higher to obtain the waveform shown by the dotted line.
Further, FIG. 10B shows a case where frequency shift is performed as frequency conversion of voice. In this case, with respect to the waveform of the voice shown by the solid line, the frequency range of 4000 Hz or higher as the high tone range is slid (shifted) to the middle tone range to obtain the waveform shown by the dotted line.
By performing such frequency conversion of the voice, it becomes possible to hear the sound in a region that cannot be heard, and it becomes easier to hear the voice.

<Modification>
In the present embodiment, the setting unit 37 grasps the situation around the own device based on the voice acquired by the acquisition unit 33, and performs the setting based on the grasped condition.
For example, the setting unit 37 sets the volume for reproducing sound in accordance with the time zone. For example, the volume is reduced at night.
Further, the setting unit 37 may grasp the situation around the own device based on the voice acquired by the acquisition unit 33, and may perform the setting based on the grasped condition. For example, when the surroundings of the own device are noisy, the volume is increased.

  According to the reproduction system 1 described in detail above, when reproducing the transmission information, it is possible to provide the reproduction system 1 capable of changing the transmission information according to the person who reproduces the transmission information.

Further, in the embodiment described in detail above, the setting unit 37, so to speak, performs the setting automatically, but the setting may be manually changed. In this case, the menu button 305c shown in FIG. 2 is pressed to change the setting from the menu displayed on the display unit 35.
Further, in the embodiment described in detail above, the reproduction system 1 is configured by connecting the mobile terminal 20 and the terminal device 30 via the network 70 and the access point 90, but the reproduction system includes only the terminal device 30. Can be regarded as The processing performed by the terminal device 30 can also be performed by the mobile terminal 20. Therefore, the mobile terminal 20 can be regarded as a reproduction system.

Furthermore, in the above-described example, the terminal device 30 is an example that is a robot, but the present invention is not limited to this. For example, it may be a mobile computer, a mobile phone, a smartphone, a mobile terminal such as a tablet, or a desktop computer.
Furthermore, in the above-described example, the terminal device 30 and the mobile terminal 20 are peer-to-peer connected via the network 70 and the access point 90, but the connection is not limited to this, and they may be connected via a server. Good. In this case, the processing performed by the terminal device 30 can also be performed by the server. Therefore, this server can be regarded as a reproduction system.
