(Operation example of the embodiment)
Next, an example of the operation of this embodiment will be described. The content playback device 10 performs voice recognition of the user's voice acquired by the microphone. When the content of the recognized voice is the content instructing the playback of the content, the content playback device 10 outputs the voice inquiring about the content to be played from the built-in speaker. When the user instructs the content to be reproduced by voice, the content reproduction device 10 performs voice recognition and acquires the recognized content.

For example, when the user plays back the content stored in the storage unit 102, the title name of the content to be played is voiced, and when playing a radio broadcast distributed on the Internet, the name of the broadcasting station to be viewed is voiced. Emit with. When the content reproduction device 10 (acquisition unit 1001) recognizes the title name of the content stored in the storage unit 102, the content reproduction device 10 (acquisition unit 1001) acquires the content of the recognized title name from the storage unit 102. Further, when the content reproduction device 10 (acquisition unit 1001) recognizes the name of the broadcasting station of the radio broadcast, the content reproduction device 10 (acquisition unit 1001) controls the communication unit 105 to acquire the data of the radio broadcast distributed by the recognized broadcasting station.

Next, the content reproduction device 10 performs a process of selecting an output destination of the audio signal before outputting the audio signal of the audio of the content. FIG. 4 is a flowchart showing a flow of processing for selecting an output destination of an audio signal. First, the content reproduction device 10 (specific unit 1003) analyzes the digital signal supplied from the microphone of the voice processing unit 107 and detects the noise level (step SA1).

Next, the content reproduction device 10 (selection unit 1004) specifies the attribute of the content to be reproduced (step SA2). The content playback device 10 identifies that the attribute of the content is radio broadcasting when reproducing the sound of the radio broadcast, and identifies that the attribute of the content is music when reproducing the content of the music acquired from the storage unit 102. do.

Next, the content reproduction device 10 (selection unit 1004) selects an output destination of the audio signal of the content (step SA3). Here, the content reproduction device 10 selects an output destination according to the level detected in step SA1 and the attribute of the content specified in step SA2. Specifically, when the attribute of the content to be reproduced is a musical piece and the detected noise level is less than a predetermined threshold value, the content reproduction device 10 selects it as an audio signal output destination at the start of step SA3. The output destination is set as the output destination of the audio signal. For example, in the content reproduction device 10, the attribute of the content to be reproduced is music, the detected noise level is less than a predetermined threshold value, and the output destination of the audio signal is the external speaker 20 at the start of step SA3. If so, the external speaker 20 is selected as the output destination of the audio signal. Further, when the attribute of the content to be reproduced is music and the detected noise level is equal to or higher than a predetermined threshold value, the content reproduction device 10 selects the headphones 40 as the output destination of the audio signal. Further, when the attribute of the content to be reproduced is radio broadcasting and the detected noise level is less than a predetermined threshold value, the content reproduction device 10 selects the built-in speaker as the output destination of the audio signal. Further, when the attribute of the content to be reproduced is radio broadcasting and the detected noise level is equal to or higher than a predetermined threshold value, the content reproduction device 10 selects the headphones 40 as the output destination of the audio signal. The content reproduction device 10 (selection unit 1004) controls the audio processing unit 107, the short-range communication unit 106, and the output unit 103 so that the audio of the content is output from the selected output destination.

Next, the content playback device 10 (selection unit 1004) notifies the user of the selected output destination (step SA4). When the content reproduction device 10 (reproduction unit 1002) notifies the output destination of the audio signal, the content reproduction device 10 reproduces the acquired content (step SA5). For example, when the output destination selected as the output destination of the audio signal is the external speaker 20, the content reproduction device 10 outputs the voice "output the voice by the external speaker" from the built-in speaker. Next, the content reproduction device 10 starts reproduction of the content, and outputs an audio signal representing the sound of the reproduced content from the output unit 103 to the external speaker 20. The external speaker 20 outputs the sound represented by the sound signal supplied from the content reproduction device 10. Further, when the output destination selected as the output destination of the audio signal is the headphone 40, the content playback device 10 outputs the sound "output the sound with the headphones" from the built-in speaker. Next, the content reproduction device 10 starts reproduction of the content, and outputs an audio signal representing the voice of the reproduced content from the short-range communication unit 106. The headphone 40 acquires an audio signal supplied from the content reproduction device 10 and outputs an audio represented by the acquired audio signal. Further, when the output destination selected as the output destination of the audio signal is the built-in speaker, the content playback device 10 outputs the voice "output the voice by the built-in speaker" from the built-in speaker. Next, the content reproduction device 10 starts reproduction of the content and outputs the sound of the reproduced content by the built-in speaker.

When the content reproduction device 10 starts reproduction of the content, the content reproduction device 10 performs the process of FIG. The content playback device 10 (specification unit 1003) analyzes the digital signal supplied from the microphone of the voice processing unit 107 and detects the noise level (step SB1). For example, the content reproduction device 10 cancels the user's voice and the voice represented by the output voice signal in the digital signal supplied from the microphone, and sets the level of the canceled voice as the noise level.

Next, the content playback device 10 (selection unit 1004) selects an output destination of the audio signal of the content (step SB2). Here, the content reproduction device 10 selects an output destination according to the level detected in step SB1 and the attribute of the content specified in step SA2. The noise level detected in step SB1 is an example of the situation around the content reproduction device 10. That is, the content reproduction device 10 selects an output destination according to the surrounding conditions of the content reproduction device 10 and the attributes of the content.

Specifically, when the attribute of the content to be reproduced is a musical piece and the detected noise level is less than a predetermined threshold value, the content reproduction device 10 selects it as an audio signal output destination at the start of step SB2. The output destination is set as the output destination of the audio signal. For example, in the content reproduction device 10, when the attribute of the content to be reproduced is a musical piece and the output destination of the audio signal is the external speaker 20 at the start of step SB2, the external speaker 20 is selected as the output destination of the audio signal. do. Further, when the attribute of the content to be reproduced is music and the detected noise level is equal to or higher than a predetermined threshold value, the content reproduction device 10 selects the headphones 40 as the output destination of the audio signal.

Further, when the attribute of the content to be reproduced is radio broadcasting and the detected noise level is less than a predetermined threshold value, the content reproduction device 10 selects the built-in speaker as the output destination of the audio signal. Further, when the attribute of the content to be reproduced is radio broadcasting and the detected noise level is equal to or higher than a predetermined threshold value, the content reproduction device 10 selects the headphones 40 as the output destination of the audio signal.

Next, the content reproduction device 10 (selection unit 1004) determines whether the output destination of the audio signal at the start of step SB2 and the output destination of the audio signal selected in step SB2 are the same (step SB3). When the output destination of the audio signal at the start of step SB2 and the output destination of the audio signal selected in step SB2 are the same (YES in step SB3), the content playback device 10 transfers the processing flow to step SB8. Move.

The content playback device 10 (selection unit 1004) outputs an audio signal when the output destination of the audio signal at the start of step SB2 and the output destination of the audio signal selected in step SB2 are different (NO in step SB3). Output an audio inquiring whether to make the previous change (step SB4).

For example, when the attribute of the content is music, the output destination of the audio signal is the external speaker 20, and the noise level is less than the threshold value, and the noise level is equal to or higher than the threshold value, the audio signal output destination is in step SB2. The headphone 40 is selected as the headphone 40, and the output destination of the audio signal at the start of step SB2 and the output destination of the audio signal selected in step SB2 are in different states. In this case, the content playback device 10 determines NO in step SB3, and outputs, for example, the sound "Do you want to change the sound output destination to headphones?" From the built-in speaker, and changes the sound output destination. Ask the user if not.

Further, when the attribute of the content is radio broadcasting, the output destination of the audio signal is the built-in speaker, and the noise level is less than the threshold value, and the noise level is equal to or higher than the threshold value, the audio signal output destination is in step SB2. The headphone 40 is selected as the headphone 40, and the output destination of the audio signal at the start of step SB2 and the output destination of the audio signal selected in step SB2 are in different states. In this case, the content playback device 10 determines NO in step SB3, and outputs, for example, the sound "Do you want to change the sound output destination to headphones?" From the built-in speaker, and changes the sound output destination. Ask the user if not.

Further, when the attribute of the content is radio broadcasting, the output destination of the audio signal is the headphone 40, and the noise level is equal to or higher than the threshold value, and the noise level becomes less than the threshold value, the output destination of the audio signal in step SB2. The built-in speaker is selected as, and the output destination of the audio signal at the start of step SB2 and the output destination of the audio signal selected in step SB2 are in different states. In this case, the content playback device 10 determines NO in step SB3, outputs an audio signal representing the audio such as "Do you want to change the audio output destination to the built-in speaker?" To the headphones 40, and outputs the audio. Ask the user if they want to change the destination.

The user emits a voice according to the voice output in step SB4. When the user emits a voice, the content reproduction device 10 (voice recognition unit 1005) performs voice recognition (step SB5). Next, the content reproduction device 10 (selection unit 1004) determines whether the result of the voice recognition is the content instructing the change of the output destination of the voice signal (step SB6). As a result of voice recognition, when the voice uttered by the user does not indicate the change of the output destination (NO in step SB6), the content playback device 10 does not change the voice output destination and follows the processing flow in step SB8. Move to. The content playback device 10 shifts the processing flow to step SB8 even if the user's voice is not recognized even after a predetermined time has elapsed after the processing in step SB4 is completed. May be good.

When the voice emitted by the user indicates the change of the output destination (YES in step SB6), the content playback device 10 (selection unit 1004) changes the output destination of the voice to the output destination selected in step SB2. (Step SB7). For example, when the content playback device 10 changes the output destination of the audio signal from the external speaker 20 to the headphones 40, the content playback device 10 stops the output of the audio signal to the external speaker 20 and transmits the audio signal from the short-range communication unit 106 by wireless communication. Output to headphones 40. As a result, the sound of the content is not output from the external speaker 20, and the sound of the content is output from the headphones 40. Since the user hears the sound output from the headphones 40 in a situation where the noise level is high, the user can hear the sound of the content without being interrupted by the noise.

Further, when the output destination of the audio signal is changed from the built-in speaker to the headphone 40, the content playback device 10 stops the supply of the audio signal to the built-in speaker and transmits the audio signal from the short-range communication unit 106 by wireless communication to the headphone 40. Output to. As a result, the sound of the content is not output from the built-in speaker, and the sound of the content is output from the headphone 40. Since the user hears the sound output from the headphones 40 in a situation where the noise level is high, the user can hear the sound of the content without being interrupted by the noise.

Further, when the output destination of the audio signal is changed from the headphone 40 to the built-in speaker, the content reproduction device 10 stops the output of the audio signal from the short-range communication unit 106 and supplies the audio signal to the built-in speaker. As a result, the sound of the content is not output from the headphones 40, and the sound of the content is output from the built-in speaker. In a situation where the noise level is low, the sound of the content is output from the internal speaker, so that the user can hear the sound of the content output from the built-in speaker without being interrupted by the noise.

After finishing the process of step SB7, the content reproduction device 10 determines whether the content reproduction is completed when it is determined to be YES in step SB3 or NO in step SB6 (step SB8). For example, when the content reproduction device 10 is reproducing the content acquired from the storage unit 102, the content reproduction device 10 determines that the reproduction of the content is not completed unless the reproduction of the content is completed, and proceeds to the process flow to step SB1. return. Further, when the content reproduction device 10 does not recognize the voice of the user instructing to stop the reproduction of the content, the process flow is returned to step SB1. When the content reproduction device 10 finishes the reproduction of the content acquired from the storage unit 102, the content reproduction device 10 determines in step SB8 that the reproduction of the content is completed, and ends the process of FIG. Further, when the content reproduction device 10 recognizes the voice of the user instructing to stop the reproduction of the content, it determines that the reproduction of the content is completed in step SB8, and ends the process of FIG.

According to the present invention, the output destination of the audio signal is changed according to the attributes of the content and the surrounding conditions of the content playback device 10. Therefore, even if the situation of viewing the content changes, the audio can be appropriately produced according to the content. You can watch it.
