Thereby, it is possible to easily convert speech to text. Furthermore, by having a path for outputting an audio signal to the output terminal 122 for connection to another device, the audio signal output from the information processing device 200 can be output to an external device other than the information processing device 200. . Thus, for example, by connecting the output terminal 122 to headphones, it is possible to check the text information converted by the information processing device 200 while listening to the audio output from the headphones.

FIG. 4 is a diagram showing a third specific example of the structure of the audio processing device 100 shown in FIG. 1. In the third specific example, the audio processing device 100 shown in FIG. 1 includes a plug section 110 in which connection sections 111 to 113 are arranged, and a main body section 132 in which a path control section 123 is arranged, as shown in FIG. It consists of The connecting portions 111 to 113 are the same as those in the first specific example shown in FIG. Note that the explanation already described in the first or second specific example may be omitted.

The path control section 123 has a path through which the audio signals input by the connection sections 111 and 112 are output from the connection section 113.

It also has a path through which an audio signal input from the outside via the input terminal 124 is output from the connection unit 113 to the information processing device 200 . These routes may be physically established by hardware such as copper wire connections (wiring), or may be established by control using software. The output terminal 122 is the same as in the second embodiment shown in FIG. For example, the input terminal 124 may be connected in place of an audio input terminal included in an audio output device such as a speaker that outputs an audio signal, or may be used to convey an audio signal input from an audio input device such as a microphone. It may also be connected to a plug that terminates the cable.

Thereby, it is possible to easily convert speech to text. Furthermore, by having a path for outputting an audio signal to the output terminal 122 for connection to another device, the audio signal output from the information processing device 200 can be output to an external device other than the information processing device 200. . Thus, for example, by connecting the output terminal 122 to headphones, it is possible to check the text information converted by the information processing device 200 while listening to the audio output from the headphones. Furthermore, by providing a path for inputting audio signals from an external device connected to the input terminal 124 to the information processing device 200, audio signals from the outside can be input to the information processing device 200. As a result, for example, if the output terminal 122 and the input terminal 124 are connected to a headset (combined microphone and headphones), the information processing device 200 can be used while listening to the audio output from the headphones of the headset. Check the character information to be converted, and if it is converted to an incorrect character or if it is necessary to add or modify characters, temporarily stop the audio playback of the audio playback unit 230 and output the audio from the headset microphone. By inputting the information, it is possible to generate text information that is more appropriate than text information that is generated only from the reproduced audio. Furthermore, when transcribing the audio of an online meeting or the like using the information processing device 200, not only the audio of a user participating in the meeting using a device that communicates with the information processing device 200 but also operating the information processing device 200 may be used. Voices emitted by the user himself (wearing a headset connected to the audio processing device 100 connected to the information processing device 200) can also be converted into text information.

FIG. 5 is a diagram showing a fourth specific example of the structure of the audio processing device 100 shown in FIG. 1. In the fourth specific example, as shown in FIG. 5, the audio processing device 100 shown in FIG. It consists of The connecting portions 111 to 113 are the same as those in the first specific example shown in FIG.

Moreover, the route control unit 125 has a route through which the audio signals inputted by each of the connection units 111 and 112 are outputted to the outside from each of the two output terminals 122. It also has a path through which an audio signal input from the outside via the input terminal 124 is output from the connection unit 113 to the information processing device 200 . These routes may be established physically using hardware such as copper wire connections (wiring), or may be established through control using software. The output terminal 122 is the same as in the second embodiment shown in FIG. The input terminal 124 is the same as in the third embodiment shown in FIG. The switch unit 126 selects the audio signal to be output from the connection unit 113 to the information processing device 200 from the audio signals input by the connections 111 and 112 and the audio signal input from the input terminal 124. In other words, by using the switch section 126, the audio signals input by the connecting sections 111 and 112 can be output from the connecting section 113 to the information processing device 200, or the audio signals input from the input terminal 124 can be output from the connecting section 113 to the information processing device 200. It is possible to select whether to output to the device 200. For example, a physical switch such as a slide switch or a toggle switch that can be operated from the outside is provided on the casing of the main body 133 of the audio processing device 100, and the route selection of the switch unit 126 is controlled by operating the switch from the outside. Anything you can do is fine. In addition, a mechanism is provided to detect the audio signals from the connecting parts 111 and 112 and the audio signal from the input terminal 124, and when the input of the audio signal from the connecting parts 111 and 112 is detected, the switch part 126 is activated. If a path is selected that outputs the audio signals from the connection units 111 and 112 from the connection unit 113 to the information processing device 200, and input of the audio signal is detected from the input terminal 124, the switch unit 126 outputs the audio signal from the input terminal 124. A route may be selected that outputs the audio signal from the connection unit 113 to the information processing device 200. Note that the selection is not only the selection of audio signals from the connections 111 and 112 or the audio signal from the input terminal 124, but also the selection of the audio signals from the connections 111 and 112 and the audio signal from the input terminal 124. The selection may be such that the output is output from the section 113 to the information processing device 200, or the selection is made such that neither the audio signals from the connection sections 111 and 112 nor the audio signal from the input terminal 124 are connected to the connection section 113.

By setting the structure of the speech processing device 100 of the present invention to the structure shown in FIG. The audio signal output from the processing device 200 can be easily input to the information processing device 200 by the audio processing device 100. Thereby, it is possible to easily convert speech to text. Furthermore, by having a path for outputting an audio signal to the output terminal 122 for connection to another device, the audio signal output from the information processing device 200 can be output to an external device other than the information processing device 200. . Thus, for example, by connecting the output terminal 122 to headphones, it is possible to check the text information converted by the information processing device 200 while listening to the audio output from the headphones. Furthermore, by providing a path for inputting audio signals from an external device connected to the input terminal 124 to the information processing device 200, audio signals from the outside can be input to the information processing device 200. With this, for example, if you connect the output terminal 122 and the input terminal 124 to a headset, you can check the character information to be converted by the information processing device 200 while listening to the audio output from the headphones of the headset, and check the character information to be converted by the information processing device 200. By inputting audio from the headset's microphone, text information that is more appropriate than text information generated from only the audio being played is generated when the text is converted to , or when characters need to be added or modified. can do. In addition, by providing a switch unit 126 that selects the audio signal to be output from the connection unit 113 to the information processing device 200 from the audio signals input by the connection units 111 and 112 and the audio signal input from the input terminal 124. , a desired audio signal can be supplied to the information processing device 200.

Modifications based on any one of the first to fourth specific examples of the audio processing device 100 of the present invention or any combination thereof will be described below. In the first to fourth specific examples shown in FIGS. 2 to 5, the connection parts 111 and 112 are connected to the path control parts 120, 121, 123, and 125 in the housings of the main bodies 130 to 133, respectively. Although there was a path through which the input audio signal was output from the connection unit 113, the modified example does not have this path. FIG. 6 is a diagram showing a first modification of the audio processing device 100 of the present invention. As shown in FIG. 6, the audio processing device 100 is provided with a headphone terminal 300 as a first terminal and a plug 400 as a second terminal, and is connected to the main body using a cord. The headphone terminal 300 is connected to the connecting portions 111 and 112 via wiring (including a cord; the same applies to the following description) in the same way as the output terminal 122 shown in FIG. 3, FIG. 4, or FIG. 5. Audio signals input to each of the connection units 111 and 112 of the audio processing device 100 are output from the headphone terminal 300. For example, by inserting a headphone plug into the jack of the headphone terminal 300, it is possible to listen to audio corresponding to the audio signal output from the headphone terminal 300. The plug 400 has a structure similar to that of a general headphone plug, and is connected to the connection portion 113 via wiring in the same manner as the input terminal 124 shown in FIG. 4 or 5. The audio signal input from the plug 400 is outputted by the audio processing device 100 via the connection unit 113 and inputted to the information processing device 200. At this time, if the input audio signal is stereo, it may be converted to monaural as in the first to fourth specific examples. Therefore, by inserting the plug 400 into the headphone terminal 300, the audio signal output from the information processing device 200 is input to the information processing device 200 via the audio processing device 100.

For this reason, in the disconnected state where the plug 400 is removed from the headphone terminal 300, the audio processing device 100, as a connection device between the information processing device 200 and the headphones, is configured to It functions optimally when the shapes of the external terminals 210 of 200 are different from each other. Further, by entering the connection state in which the plug 400 is inserted into the headphone terminal 300, the configuration is similar to that of the first specific example, the same effects are exhibited, and speech can be easily converted into text. In this way, the first modification example uses the headphone terminal 300 and the plug 400 to transmit audio signals input to the connection parts 111 and 112 to the connection part 113, like the path control part 125 in the first specific example. Realize the route output from.

FIG. 7 is a diagram showing a second modification of the audio processing device 100 of the present invention. Note that the description already described in the first modification may be omitted. As shown in FIG. 7, the audio processing device 100 is provided with a headphone terminal 300 and a plug 401 via a connector 600 with branched wiring, and is connected to the main body using a cord. The audio processing device 100 is also provided with a microphone terminal 500 and connected to the main body using a cord. Headphone terminal 300 and plug 401, which is a first terminal, are each connected to connection parts 111 and 112 via wiring and connector 600, similar to output terminal 122 shown in FIG. 3, FIG. 4, or FIG. Audio signals input to each of the connection sections 111 and 112 of the audio processing device 100 are output from the headphone terminal 300 and the plug 401. For example, by inserting a headphone plug into the jack of the headphone terminal 300, it is possible to listen to audio corresponding to the audio signal output from the headphone terminal 300. Further, by inserting the plug 401 into the input terminal of another device capable of outputting audio, it is possible to listen to audio corresponding to the audio signal output from the plug 401. The microphone terminal 500, which is the second terminal, is connected to the connection portion 113 via wiring, similar to the input terminal 124 shown in FIG. 4. For example, when a microphone plug is inserted into the jack of the microphone terminal 500, the audio signal input from the plug inserted into the microphone terminal 500 is outputted by the audio processing device 100 via the connection unit 113, and the information processing It is input to the device 200.

By inserting the plug 401 into the microphone terminal 500, an audio signal output from the information processing device 200 is input to the information processing device 200 via the audio processing device 100. For this reason, in the disconnected state where the plug 401 is removed from the microphone terminal 500, the audio processing device 100 acts as a connection device between the information processing device 200 and the headphones or microphone, especially depending on the shape of the plug of the headphones or microphone that you own. It functions optimally when the shape of the external terminal 210 of the information processing device 200 is different. Further, by entering the connection state in which the plug 401 is inserted into the microphone terminal 500, the configuration is similar to that of the second specific example, the same effects are exhibited, and speech can be easily converted into text. Furthermore, by connecting headphones to the headphone terminal 300, it is possible to check the text information converted by the information processing device 200 while listening to the audio output from the headphones. In this way, the second modification uses the microphone terminal 500 and the plug 401 so that the audio signals input by the connection parts 111 and 112 are transmitted to the connection part 113, like the path control part 125 in the second specific example. Realize the route output from.

Note that the description already described in the first or second modification may be omitted. As shown in FIG. 8, the audio processing device 100 is provided with a headphone terminal 300 and a plug 401, which is a first plug, through a connector 600 where wiring is branched, and connected to the main body using a cord. There is. That is, the headphone terminal 300 and the plug 401 are respectively similar to those shown in FIG. Furthermore, the audio processing device 100 is provided with two microphone terminals 500-1 and 500-2 through a connector 600 where wiring is branched, and is connected to the main body using a cord. Microphone terminal 500-1 or 500-2 is the second terminal. Each of the microphone terminals 500-1 and 500-2 is connected to the connection portion 113 via wiring and a connector 600, similar to the input terminal 124 shown in FIG. In other words, the two microphone terminals 500-1 and 500-2 are the same as the microphone terminal 500 shown in FIG. 7. For example, when a microphone plug is inserted into one of the microphone terminals 500-1 and 500-2, an audio signal input from the inserted plug is transmitted to the audio processing device 100 via the connection unit 113. The data is output and input to the information processing device 200.

Therefore, by inserting the plug 401 into the microphone terminal 500-1 or 500-2, the audio signal output from the information processing device 200 is input to the information processing device 200 via the audio processing device 100. Therefore, in the disconnected state where the plug 401 is removed from the microphone terminal 500-1 or 500-2, the audio processing device 100 is used as a connection device between the information processing device 200 and the headphones or microphone. It functions optimally when the shape of the microphone plug and the shape of the external terminal 210 of the information processing device 200 are different. In addition, by entering the connection state in which the plug 401 is inserted into the microphone terminal 500-1 or 500-2, the configuration is similar to that of the third specific example, the same effect is exhibited, and the conversion from voice to text is facilitated. can be done. Furthermore, by connecting headphones to the headphone terminal 300 and connecting a microphone to the microphone terminal 500-1 or 500-2 to which the plug 401 is not inserted, the information processing device 200 can be used while listening to the audio output from the headphones. By being able to confirm the text information to be converted and also inputting voice from the microphone, it is possible to generate more appropriate text information than text information generated only from the reproduced voice. In addition, when transcribing audio from an online meeting, etc., the user himself/herself may emit audio while operating the information processing device 200 (using a microphone connected to the audio processing device 100 connected to the information processing device 200). It can be converted into text information. Further, by inserting and removing the plug 401 and the microphone from the microphone terminal 500-1 or 500-2, the configuration is similar to that of the switch section 126 shown in FIG. 5, and the same effects as the fourth specific example can be achieved.

FIG. 9 is a diagram showing a fourth modification of the audio processing device 100 of the present invention. Note that the description already described in any of the first to third modifications may be omitted. As shown in FIG. 9, the audio processing device 100 is provided with two headphone terminals 300-1 and 300-2 through a connector 600 where wiring is branched, and connected to the main body using a cord. . Two headphone terminals 300-1 or 300-2 are first terminals. Further, the audio processing device 100 is provided with a microphone terminal 500 and a plug 401 which is a second terminal via a connector 600 where wiring is branched, and is connected to the main body using a cord. The headphone terminals 300-1, 300-2 are connected to the connecting portions 111, 112 via wiring and the connector 600, similar to the output terminal 122 shown in FIG. 3, FIG. 4, or FIG. Further, the microphone terminal 500 and the plug 400 are each connected to the connection portion 113 via wiring and the connector 600, similarly to the input terminal 124 shown in FIG. In the fourth modification, the headphone terminal 300 shown in FIG. 8 becomes the headphone terminal 300-1, the plug 401 becomes the headphone terminal 300-2, the microphone terminal 500-1 shown in FIG. 8 becomes the plug 400, and the microphone terminal 500-2 is a microphone terminal 500. In other words, the fourth modification shown in FIG. 9 differs from the modification shown in FIG. 8 in that the shape of one of the two terminals of the headphone and microphone is a plug or a jack. The only difference is that the same effect as the third modification can be achieved by connecting or disconnecting the plug 400 to the headphone terminal 300-1 or 300-2.

Although the description has been given using a 4-pole mini plug as an example of the plug section 110, the plug section 110 may also be a connector connected to a USB (Universal Serial Bus) port that has terminals for inputting and outputting audio signals, or a connector that connects input and output terminals. It is also possible to use other connectors, such as those that have physically separate plugs.

By using the audio processing device 100 in the configurations shown in FIGS. 6 to 9, the audio processing device 100 not only outputs the audio signal input from the information processing device 200 to the information processing device 200, but also outputs the audio signal to the outside. It is also possible to output signals and input audio signals from the outside. If the audio signal can be output to the outside, it is possible to check the information converted into text by the information processing device 200 while listening to the audio corresponding to the output audio signal. Furthermore, if it is possible to input an audio signal from the outside, it is possible to input the audio signal from the outside to the information processing device 200 while listening to the audio corresponding to the output audio signal. In this way, speech can be easily converted into text.
