[0049] According to an embodiment of the present disclosure, the voice service end performs text-to-speech conversion on the i-th text segment among the M text segments, and sends the converted i-th audio stream to the gateway device.

[0050] In operation S230, in response to the i-th audio stream being the first audio stream, an audio broadcast start instruction is sent to the voice broadcast device, wherein the audio broadcast start instruction includes text information that needs to be audio broadcasted.

[0051] According to an embodiment of the present disclosure, when a gateway device receives the i-th audio stream, it can match the identification information of the i-th audio stream with the identification of the first segment of text information stored in the gateway device. If the match is consistent, the i-th audio stream can be determined as the first segment of the audio stream.

[0052] According to an embodiment of the present disclosure, the text information stored in the gateway device has a text start identifier and a text end identifier, so that the voice server can accurately split the text information and identify the text start and end information during the text-to-speech conversion process.

[0053] According to an embodiment of the present disclosure, the audio broadcast start instruction may be the first part of the audio instruction, and the audio broadcast start instruction may be an instruction for enabling the voice broadcast device to start the audio broadcast task. The voice broadcast device is used to broadcast the audio stream sent by the gateway device.

[0054] According to an embodiment of the present disclosure, when it is determined that the i-th audio stream is the first audio stream, the first part of the audio instruction "audio broadcast start instruction" is sent to the voice broadcast device. After receiving the audio broadcast start instruction, the voice broadcast device starts the audio broadcast task.

[0055] According to an embodiment of the present disclosure, the audio broadcast start instruction includes text information that needs to be broadcasted, that is, after receiving the audio broadcast start instruction, the voice broadcast device receives the text information corresponding to the audio that needs to be broadcasted. The audio broadcast start instruction may include the following parts, as shown in Table 1:

[0056] Table 1

[0057] TTS audio broadcast command content: After receiving the first TTS audio, it is sent to the device, including the following content:

[0058]

[0059] In operation S240, in response to the voice broadcast device receiving the audio broadcast start instruction, a first audio stream is sent to the voice broadcast device, so that the voice broadcast device broadcasts the first audio stream.

[0060] According to an embodiment of the present disclosure, after the voice broadcast device receives the audio broadcast start instruction and starts the audio broadcast task, the gateway device sends the i-th audio stream as the first audio stream to the voice broadcast device, and the voice broadcast device broadcasts the first audio stream.

[0061] According to an embodiment of the present disclosure, a text-to-speech conversion request is sent to a voice server, the i-th audio stream generated by the voice server is received, and in response to the i-th audio stream being the first audio stream, an audio broadcast start instruction is sent to a voice broadcast device, and the first audio stream is sent to the voice broadcast device, so that the voice broadcast device broadcasts the first audio stream. Since the broadcast instruction is sent to the voice broadcast device and the first audio stream is sent to the voice broadcast device when the received audio stream generated by the voice server is the first audio stream, so that the voice broadcast device can first receive the first audio stream for broadcasting, the technical means of sending the audio stream in segments in a streaming manner is implemented, at least partially overcoming the technical problem that the time taken from receiving the converted text to the device starting to broadcast the complete audio file in traditional voice broadcast is too long, and the response time of the first audio broadcast is reduced, thereby achieving the technical effect of improving the response time of the first audio broadcast and improving the user experience.

[0062] According to an embodiment of the present disclosure, the method may further include: in response to the i-th audio stream not being the first audio stream, sending the i-th audio stream to a voice broadcasting device, so that the voice broadcasting device broadcasts the i-th audio stream.

[0063] According to an embodiment of the present disclosure, when the gateway device determines that the i-th audio stream sent by the voice server is not the first audio stream, it means that the gateway device has received the first audio stream and sent an audio broadcast start instruction to the voice broadcast device. The voice broadcast device has started the audio playback task. At this time, the received i-th audio stream is directly sent to the voice broadcast device, so that the voice broadcast device broadcasts the i-th audio stream.

[0064] According to an embodiment of the present disclosure, the method also includes: in response to the start broadcast of the i-th audio stream, cyclically executing the sending of the i+1-th audio stream to the voice broadcast device, so that the voice broadcast device broadcasts the i+1-th audio stream, until the voice broadcast device broadcasts the M-th audio stream, wherein the i+1-th audio stream is obtained by the voice server performing text-to-speech conversion on the i+1-th text segment among the M text segments of the text information, and the M-th audio stream is obtained by the voice server performing text-to-speech conversion on the M-th text segment among the M text segments of the text information; in response to broadcasting the M-th audio stream, sending an audio broadcast end instruction to the voice broadcast device, so that the voice broadcast device performs an audio broadcast end operation.

[0065] According to an embodiment of the present disclosure, when the i-th audio stream is the first audio stream, when the voice broadcast device starts to broadcast the first audio stream, the gateway device end has received the second audio stream converted and generated by the voice server end, and sends the second audio stream to the voice broadcast device so that the voice broadcast device starts to broadcast the second audio stream; the execution is cyclically executed in sequence, the gateway device end continues to send the i-th audio stream that has been received and generated by the voice server end to the voice broadcast device so that the voice broadcast device starts to broadcast the i-th audio stream, and sends the i+1-th audio stream to the voice broadcast device so that the voice broadcast device broadcasts the i+1-th audio stream, until the M-th audio stream that has been received and generated by the voice server end is sent to the voice broadcast device so that the voice broadcast device starts to broadcast the M-th audio stream.

[0066] According to an embodiment of the present disclosure, the operation of cyclically executing the audio stream broadcast is that when the voice broadcast device starts to broadcast the first audio segment, the gateway device sends the second part "audio" of the audio instruction to the voice broadcast device, so that the voice broadcast device receives the audio stream in segments and cyclically executes the segmented playback. The content of the audio may include the following table 2.

[0067] Table 2

[0068] Audio, send all audio streams in a loop

[0069]

[0070] According to an embodiment of the present disclosure, when the i-th audio stream is not the first audio stream and the voice broadcast device starts broadcasting the i-1-th audio stream, the gateway device has received the i-th audio stream converted and generated by the voice server, and sends the i-th audio stream to the voice broadcast device so that the voice broadcast device starts broadcasting the i-th audio stream; the process is executed in a loop until the voice broadcast device starts broadcasting the M-1-th audio stream, at which point the gateway device has received the M-th audio stream converted and generated by the voice server, and sends the M-th audio stream to the voice broadcast device so that the voice broadcast device starts broadcasting the M-th audio stream.

[0071] According to an embodiment of the present disclosure, when the gateway device receives the Mth audio stream, it can determine that the Mth audio stream is the last audio stream based on the identification information of the Mth audio stream. After sending the Mth audio stream to the voice broadcast device, an audio broadcast end instruction is sent to the voice device. After the voice broadcast completes the Mth audio stream, the audio broadcast ends the operation and closes the audio broadcast task.

[0072] According to an embodiment of the present disclosure, the audio broadcast end instruction is the third part of the audio instruction. After the gateway device sends the last audio stream to the voice broadcast device, the third part of the audio instruction "audio broadcast end instruction" is sent to the voice broadcast device so that the voice broadcast device ends the audio broadcast task after broadcasting the last audio stream. The content of the audio broadcast end instruction may include the following table 3.
