Broadcast system, terminal apparatus, method for operating terminal apparatus, and recording medium

1. A broadcast system comprising:

at least one processor that implements instructions stored in a memory to:

acquire a first audio signal and a second audio signal, wherein:

the first audio signal includes:

a first voice;

and a first sound component representative of a piece of first identification information corresponding to a piece of first related information related to the first voice, the piece of first related information being provided from a distribution apparatus via a communication network to a terminal apparatus, and

the second audio signal includes:

a second voice;

and a second sound component representative of a piece of second identification information corresponding to a piece of second related information related to the second voice, the piece of second related information being registered in advance in a storage device of the terminal apparatus; and

switch, in response to a switch instruction, from one to another among a plurality of broadcast operations, the plurality of broadcast operations including:

a first broadcast operation that transmits the acquired first audio signal that includes both the first voice and the first sound component to a playback apparatus, which outputs the first audio signal from a speaker of the playback apparatus; and

a second broadcast operation that transmits the acquired second audio signal that includes both the second voice and the second sound component to the playback apparatus, which outputs the second audio signal from the speaker of the playback apparatus,

wherein the at least one processor, in switching to the first or second broadcast operation, adds trigger data to the respective first or the second audio signal, which is transmitted immediately before or after the switching to the first or second broadcast operation is carried out, the trigger data being a command causing the terminal apparatus to switch from one to another among:

a first acquiring operation to acquire the piece of first related information related to the first voice from the distribution apparatus based on the piece of first identification information; and

a second acquiring operation to acquire the piece of second related information related to the second voice from the storage device of the terminal apparatus based on the piece of second identification information.

2. The broadcast system according to claim 1 , wherein the first piece of related information is text representative of a spoken content of the first voice.

3. The broadcast system according to claim 1 , wherein the second voice is a voice that provides fixed-phrase information.

4. The broadcast system according to claim 1 , further comprising: the terminal apparatus, which receives the first or second audio signal.

5. A terminal apparatus comprising:

a microphone configured to generate an audio signal from a playback sound output from a speaker of a playback apparatus, the playback sound including a first voice or a second voice;

a storage device that includes a plurality of pieces of second identification information registered in association with respective corresponding pieces of second related information, each of the pieces of second related information being related to a corresponding one of a plurality of second voices including the second voice; and

at least one processor that implements instructions stored in a memory to:

extract a piece of identification information from the audio signal generated by the microphone;

determine whether trigger data is included in the audio signal, the trigger data being a command to switch from one to another among:

a first acquiring operation to acquire a piece of first related information related to the first voice from a distribution apparatus; and

a second acquiring operation to acquire, from the storage device, a piece of second related information related to the second voice; and

switch, based on the trigger data being included in the audio signal, to one to another among:

the first acquiring operation based on the extracted piece of identification information, the first acquiring operation transmitting, via a communication network, the extracted piece of identification information to the distribution apparatus; and

the second acquiring operation based on the extracted piece of identification information corresponding to a piece of second identification information, among the plurality of second related information; and

perform the switched one of the first or second acquiring operation.

6. The terminal apparatus according to claim 5 , wherein: the first piece of related information is representative of text that represents a spoken content of the first voice.

7. A method of operating a terminal apparatus including a storage device and a microphone that generates an audio signal from a playback sound output from a speaker of a playback apparatus, the playback sound including a first voice or a second voice, the method comprising:

storing, in the storage device, a plurality of pieces of second identification information registered in association with respective corresponding pieces of second related information, each of the pieces of second related information being related to a corresponding one of a plurality of second voices including the second voice;

extracting a piece of identification information from the audio signal generated by the microphone;

determining whether trigger data is included in the audio signal, the trigger data being a command to switch from one to another among:

a first acquiring operation to acquire a piece of first related information related to the first voice from a distribution apparatus; and

a second acquiring operation to acquire, from the storage device, a piece of second related information related to the second voice;

switching, based on the trigger data being included in the audio signal, to one to another among:

the first acquiring operation based on the extracted piece of identification information, the first acquiring operation transmitting, via a communication network, the extracted piece of identification information to the distribution apparatus; and

the second acquiring operation based on the extracted piece of identification information corresponding to a piece of second identification information, among the plurality of second related information; and

performing the switched one of the first or second acquiring operation.

8. A non-transitory computer-readable recording medium storing a program executable by a computer to execute a method of operating a terminal apparatus including a storage device and a microphone that generates an audio signal from a playback sound output from a speaker of a playback apparatus, the playback sound including a first voice or a second voice, the method comprising:

storing, in the storage device, a plurality of pieces of second identification information registered in association with respective corresponding pieces of second related information, each of the pieces of second related information being related to a corresponding one of a plurality of second voices including the second voice;

extracting a piece of identification information from the audio signal generated by the microphone;

determining whether trigger data is included in the audio signal, the trigger data being a command to switch from one to another among:

a first acquiring operation to acquire a piece of first related information related to the first voice from a distribution apparatus; and

a second acquiring operation to acquire, from the storage device, a piece of second related information related to the second voice;

switching, based on the trigger data being included in the audio signal, to one to another among:

the first acquiring operation based on the extracted piece of identification information, the first acquiring operation transmitting, via a communication network, the extracted piece of identification information to the distribution apparatus; and

the second acquiring operation based on the extracted piece of identification information corresponding to a piece of second identification information, among the plurality of second related information; and

performing the switched one of the first or second acquiring operation.
