Further, for example, it may have an interface with a digital medium such as a USB terminal or a wireless communication device such as a Wi-Fi communication device or a Bluetooth communication device.

  The sound source storage unit 13 is, for example, a storage device such as a hard disk, a flash memory, or an SSD, or a part of a storage area inside the device. The sound source storage unit 13 stores the sound source data reproduced by the sound source data reproduction unit 11. The sound source data reading / reproducing unit 11 can also transmit the sound source data itself to the sound source storage unit 13 and the sound source storage unit 13 can store the data.

  The specific sound storage unit 15 is, for example, a storage device such as a hard disk, a flash memory, or an SSD, or a part of a storage area inside the device. The specific sound storage unit 15 includes a sound that may be confused by the user when the content including sound such as music or video is reproduced, a sound that may be uncomfortable for the user, or a device that supports voice recognition input. The specific sound information including the specific sound is stored as a sound (for example, speech such as speech) that may malfunction.

  Specific sounds include environmental sounds such as telephone ringtones, sirens such as ambulances or police cars, or sounds emitted in emergency such as warning sounds or SOS sounds of Morse code. May be. In addition, sounds such as sudden braking sounds, impact sounds, explosion sounds, or shooting sounds may be included. In addition, a voice uttered by a person such as a person's scream or speech may be included.

  The specific sound storage unit 15 can communicate with an external database DB in which specific sound information is stored. Therefore, the specific sound storage unit 15 can access the external database DB and acquire the specific sound information in the external database DB. For example, the specific sound information in the external database DB is constantly updated, and the specific sound storage unit 13 can update its specific sound information based on the specific sound information in the external database DB.

  The specific sound detection unit 17 detects the specific sound stored in the specific sound storage unit 15 from the sound source data reproduced by the sound source data reading / reproducing unit. This detection may be performed, for example, by detecting whether sound having the same or similar frequency component as the specific sound is included in the sound source data. In addition, when speech data such as speech is included in the sound source data, speech recognition is performed to wake up the character string, and it is detected whether there is the same sound as speech such as speech included in the specific sound in the character string. May be.

  When the specific sound is detected in the sound source data, the specific sound detecting unit 17 analyzes the reproduction position of the specific sound in the sound source data and generates specific sound detection information including the specific sound and position information of the specific sound. And stored in the sound source storage unit 13. The position information of the specific sound includes, for example, a sound source data name including the specific sound, a name of the music including the specific sound (music name), and a start time and an end time of the reproduction position including the specific sound within the music (Elapsed time from the start of music playback) is included. The specific sound detection information may be stored in a set with corresponding sound source data (sound source data that is a target of detection of the specific sound in the specific sound detection information).

  The control unit 19 as a reproduction control unit or determination unit is a functional unit that reproduces sound source data and displays information related to the sound source data. The control unit 19 is communicably connected to an operation display unit D such as a speaker S and a touch panel. The control unit 19 acquires sound source data from the sound source storage unit 13, reproduces it, and outputs an acoustic signal to the speaker S.

  Further, the control unit 19 controls the reproduction of the sound source data according to the operation input from the operation display unit D, for example. For example, the control unit 19 may control the reproduction, pause, or stop of the sound source data in accordance with the operation input from the operation display unit D, and may adjust the volume of the acoustic signal to be output.

  When reproducing the sound source data, the control unit 19 acquires specific sound detection information corresponding to the sound source data from the sound source storage unit 13.

It may be possible to save it. Further, it may be possible to receive sound input from a microphone (not shown) connected to the control unit 19 and store the received sound in the specific sound storage unit 15 as a specific sound.
[Specific sound detection routine]
Below, the routine at the time of detecting the specific sound performed in the specific sound detection part 17 is demonstrated. FIG. 2 shows a specific sound detection routine R1 which is an example of a routine executed when detecting a specific sound. The specific sound detection routine R1 starts, for example, when power is supplied to the playback control device 10.

  When the routine R1 is started, the specific sound detection unit 17 first determines whether sound source data is being reproduced for recording in the sound source storage unit 13 (step S1). This determination may be performed by determining whether sound source reproduction data (or signal) has arrived from the sound source data reading / reproducing unit 11.

  When the sound source data is being reproduced, the sound source data itself or the sound of the sound source data being reproduced is converted into data again and stored in the sound source storage unit 13. For example, when the sound source data is compressed data, the compressed data may be stored in the sound source storage unit 13 as it is upon reproduction by the sound source reading / reproducing unit 11. Further, the sound source data may be reproduced in an uncompressed state, and the uncompressed data or compressed data obtained by recompressing the uncompressed data may be stored in the sound source storage unit 13.

  When the sound source data includes one or a plurality of music pieces, a music list that lists the music pieces included in the sound source data together with the sound source data may be generated and stored together with the sound source data.

  If the specific sound detection unit 17 determines that the sound source data is not reproduced (step S1: NO), then the routine ends. When the specific sound detection unit 17 determines that the sound source data is being reproduced, the specific sound detection process is started (step S2).

As described above, the specific sound storage unit 15 may perform this detection process, for example, by detecting whether a sound having the same or similar frequency component as the specific sound is included in the sound source data. In addition, when speech data such as speech is included in the sound source data, speech recognition is performed to wake up the character string, and it is detected whether there is the same sound as speech such as speech included in the specific sound in the character string. May be.
When the specific sound detection process is started, it is determined in step S3 whether or not a specific sound has been detected (step S3). This determination may be performed by determining whether or not a specific sound is detected in the detection process.

  If the specific sound detection unit 17 determines in step S3 that a specific sound has been detected (step S3: YES), the specific sound detection unit 17 stores the position information of the detected specific sound in the sound source storage unit 13 (step S4). As described above, the position information of the specific sound includes, for example, the sound source data name including the specific sound, the name of the music including the specific sound (music name), and the start time and end time of the specific sound in the music. Is included.

  The specific sound detection unit 17 determines that the specific sound is not detected in step S3 (step S3: NO), or determines whether the reproduced sound source data has been reproduced to the end after the execution of step S4. (Step S5). That is, it is determined whether or not the specific sound detection process has been performed up to the end of the reproduced sound source data. This determination is performed, for example, by determining whether data indicating the end of the sound source data has been received or whether sound source reproduction data (or a signal) has yet arrived from the sound source data reading / reproducing unit 11. May be.

  If the specific sound detection unit 17 determines in step S5 that the sound source data has not been reproduced to the end (step S5; NO), the specific sound detection unit 17 continues the specific sound detection process and executes step S3 again.

If the specific sound detection unit 17 determines in step S5 that the sound source data has been reproduced to the end (step S5: YES), the specific sound detection process ends (step S6), and then the routine ends.
[Reproduction control routine 1]
Below, the routine at the time of reproducing | regenerating the sound source data preserve | saved at the sound source memory | storage part 13 performed in the control part 19 is demonstrated. FIG. 3 shows a reproduction processing routine R2 as an example of a routine for reproducing sound source data including one or a plurality of music pieces. The reproduction processing routine R2 is an example of a routine in the case where a musical piece including a specific sound is not reproduced. The regeneration processing routine R2 starts, for example, when power is supplied to the regeneration control device 10.

  When the routine R2 is started, the control unit 19 determines whether or not a reproduction start operation has been accepted (step S1). This determination may be performed, for example, by determining in the operation display unit D whether or not a reproduction start operation from the user has been accepted.

  If the control unit 19 determines that the reproduction start operation has not been received in step S1 (step S1: NO), then the routine ends. When the control unit 19 determines in step S1 that the reproduction start operation has been received (step S1: YES), the control unit 19 starts reproduction processing of the sound source data stored in the sound source storage unit 13 (step S2).

  After executing step S2, the control unit 19 determines whether or not the music to be played is a music including a specific sound. This determination may be performed by referring to the specific sound detection information stored in the sound source storage unit 13 and corresponding to the reproduction data currently being reproduced.

  When the control unit 19 determines in step S3 that the music to be played is a music including a specific sound (step S3: YES), the control unit 19 does not play the music and the music is the last in the sound source data. It is determined whether or not the song is a song (step S4). That is, it is determined whether or not there is a music piece that has not been reproduced in the sound source data. This determination may be performed, for example, with reference to a music list that is created when the sound source data is stored and stored in the sound source storage unit 13 together with the sound source data.

  In step S4, when the control unit 19 determines that the music to be reproduced is the last music (step S4: YES), the control unit 19 ends the reproduction process (step S5), and then the routine ends.

  In step S4, if the control unit 19 determines that the song that the user is trying to play is not the last song (step S4: NO), the control unit 19 searches for the next song to be played (step S6), and then Step S3 is executed again for the music to be reproduced next.

  In step S3, when the control unit 11 determines that the music to be reproduced is not a music including the specific sound (step S3: NO), the control unit 11 reproduces the music (step S7).

  After executing step S7, the control unit 11 determines whether or not the music being reproduced has ended (step S8). If the control unit 11 determines in step S8 that the music being played back has not ended (step S8: NO), the control unit 11 continues to play the music, and executes step S8 again after a certain period of time, for example.

When the control unit 11 determines in step S8 that the music being reproduced has been completed, the control unit 11 executes step S4 and determines whether or not the music being reproduced is the last music in the sound source data.
[Reproduction control routine 2]
Below, the routine at the time of reproducing the sound source data preserve | saved at the sound source memory | storage part 13 performed in the control part 19 is demonstrated. FIG. 4 shows a reproduction processing routine R3 as an example of a routine when reproducing sound source data including one or a plurality of music pieces. The reproduction processing routine R3 is an example of a routine in the case where reproduction is performed with the sound of a part including a specific sound in the music being erased. The regeneration processing routine R3 starts, for example, when power is supplied to the regeneration control device 10.

  When the routine R3 is started, the control unit 19 determines whether or not a reproduction start operation has been accepted (step S1). This determination may be performed, for example, by determining in the operation display unit D whether or not a reproduction start operation from the user has been accepted.

  If the control unit 19 determines that the reproduction start operation has not been received in step S1 (step S1: NO), then the routine ends. When the control unit 19 determines in step S1 that the reproduction start operation has been received (step S1: YES), the control unit 19 starts reproduction processing of the sound source data stored in the sound source storage unit 13 (step S2).

  After executing step S2, the control unit 19 determines whether or not to end the reproduction (step S3). This determination may be performed, for example, by determining in the operation display unit D whether or not a reproduction end (reproduction stop) operation has been received from the user. Further, for example, this determination may be performed by determining whether or not the reproduction of the sound source being reproduced has been completed.

  When the control unit 19 determines that the reproduction is finished (step S3: YES), the routine is finished thereafter. When it is determined that the reproduction is not finished (step S3: NO), the control unit 19 determines whether or not the current reproduction time point is a specific sound part, that is, a start point of a part including the specific sound (step S4). . That is, it is determined whether or not the specific sound portion has started. When determining that the current playback time point is not the start point of the specific sound portion (step S4), the control unit 19 executes step S3 again to determine whether or not to end the playback.

  When the control unit 19 determines that the current reproduction time point is the start point of the specific sound part (step S4: YES), the control unit 19 stops outputting the sound signal of the sound source being reproduced or mutes the sound signal volume ( (Step S5). That is, the output of the acoustic signal is controlled so that no sound is output from the speaker S.

  Note that the sound signal may be output by adjusting the volume such as decreasing the volume when reproducing the specific sound portion. Further, processing such as adding an acoustic effect to the sound of the specific sound portion may be performed, and output may be performed by changing to a sound that does not affect the user. That is, when the specific sound is detected from the sound source, the control unit 19 may perform an acoustic process on a portion including the specific sound.

  For example, the frequency component may be changed so that the sound of a specific sound part such as a siren does not surprise the user or does not disturb the user.

  After executing Step S5, the control unit 19 determines whether or not the current playback time point is the end point of the specific sound portion (Step S6). That is, it is determined whether or not the specific sound portion has ended. If the control unit 19 determines that the current playback time point is not the end point of the specific sound part (step S6: NO), the control unit 19 repeatedly executes step S6 until the end point of the specific sound part arrives.

  When the control unit 19 determines that the current playback time point is the end point of the specific sound part (step S6: YES), the control unit 19 cancels the mute (step S7) and executes step S3 again.

  According to the playback control apparatus of the present embodiment, the sound that may be confusing or uncomfortable for the person listening in the sound source, or the sound that may cause malfunction of the device corresponding to the voice recognition input, etc. When a specific sound is included, it is possible to prevent the specific sound from being emitted from a speaker or the like.

Thereby, it is possible to prevent the user who is listening to the sound source from being confused or uncomfortable. In addition, it is possible to prevent malfunction of a device corresponding to a voice recognition input in the vicinity of a speaker from which a reproduction sound of the sound source is output during reproduction of the sound source.
