API reference
CosyVoice long-text speech synthesis converts text submitted in a single input into speech and streams the audio as binary data. With a voice that supports Speech Synthesis Markup Language (SSML), you can add background audio, set pauses, and correct pronunciation. This topic describes endpoints, the interaction process, request parameters, response events, and supported voices.
Billing and concurrency limits
CosyVoice long-text speech synthesis is available only in the commercial version and does not offer a free trial. Activate the commercial version before use. For activation instructions and billing methods, see Billing methods.
For billable items, see Billable items.
For concurrency limits, see Concurrency and QPS.
Features and limits
Supports PCM, WAV, MP3, and OPUS audio formats.
Accepts one text input per session. The text must use UTF-8 encoding and contain no more than 10,000 characters. Streaming text input is not supported, but synthesized audio is returned as a stream.
Supports voice selection and adjustments to speech rate, pitch, and volume.
Supports SSML and word-level timestamps, depending on the voice. For details, see the voice list.
Endpoints and authentication
Select an endpoint for the network environment and set the SDK URL to that endpoint.
|
Access type |
Description |
URL |
|
Internet access |
Available to servers with Internet connectivity. |
|
|
Internal access from ECS |
Available to Elastic Compute Service (ECS) instances in a virtual private cloud (VPC) in the China (Beijing) region. The classic network is not supported. Internal access does not incur Internet traffic fees for the ECS instance. |
|
The client authenticates with an NLS token when establishing a WebSocket connection. For instructions, see Obtain a token. The Appkey in the request identifies an Intelligent Speech Interaction project. Obtain it from the Intelligent Speech Interaction console.
Interaction process
Authenticate: Establish a WebSocket connection using an NLS token.
Configure parameters: Set the Appkey, voice, audio format, sample rate, and other parameters, and initiate synthesis.
Send text: Send all text to synthesize in a single input. With an SDK, the text can be passed through the
textparameter ofstartTts.Receive data: The server streams binary audio data. The client receives the data and saves or plays it. If timestamps are enabled, also handle subtitle events.
Complete synthesis: The server sends a
SynthesisCompletedevent when all audio has been returned. This event does not indicate that the client has finished playing the audio.
Request parameters
The following tables describe the parameters. Configuration methods, parameter types, and defaults may differ across SDK languages. Use the interface for the SDK language in use. For example, the Java SDK uses setter methods on the StreamInputTts object and enums, whereas the Python SDK accepts synthesis parameters through startTts.

The text to synthesize, in UTF-8 encoding, with no more than 10,000 characters. Separate English words with spaces. Send text only once per session. |
With a voice that supports SSML, use SSML to control sentence and word segmentation, pronunciation, speed, pauses, pitch, and volume, or to add background music. For details, see SSML.
Responses
Synthesized audio is returned in binary WebSocket messages. Synthesis status and timestamps are returned as JSON events. The header.namespace field is FlowingSpeechSynthesizer.
Synthesis completion event
When the client receives SynthesisCompleted, all audio for the synthesis request has been returned. The following example shows the main fields, with redacted message_id and task_id values.
{
"header": {
"message_id": "05450bf69c53413f8d88aed1ee60****",
"task_id": "640bc797bb684bd6960185651307****",
"namespace": "FlowingSpeechSynthesizer",
"name": "SynthesisCompleted",
"status": 20000000,
"status_text": "GATEWAY|SUCCESS|Success."
},
"payload": {
"measureType": "TextLengthHD",
"measureLength": 49
}
}|
Field |
Type |
Description |
|
header.status |
Integer |
The status code. A value of 20000000 indicates success. |
|
header.status_text |
String |
The status description. |
|
payload.measureType |
String |
The metering type, such as |
|
payload.measureLength |
Integer |
The metered character count for this request. Each Chinese character counts as two characters. Each English letter, punctuation mark, or space within a sentence counts as one character. |
Word-level timestamps
Use a voice that supports timestamps and set enable_subtitle to true. For example, longxiaochun_v2 and longwan_v2 support timestamps, but longxiaochun does not. For support by voice, see the voice list.
Subtitles are returned in SentenceSynthesis and SentenceEnd events during synthesis, before the full synthesis completes. A SentenceBegin event marks the start of a sentence, with the sentence index in its payload. The main fields in subtitle events are described below.
|
Field |
Type |
Description |
|
payload.index |
Integer |
The sentence index. |
|
payload.subtitles |
Array |
The list of subtitles and their timestamps. The list may be empty if timestamps are not enabled or the voice does not support them. Even with timestamps enabled, some |
|
payload.subtitles[].text |
String |
The subtitle text. |
|
payload.subtitles[].begin_time |
Integer |
The subtitle start time, in milliseconds. |
|
payload.subtitles[].end_time |
Integer |
The subtitle end time, in milliseconds. |
Audio duration and text synchronization
Synthesized audio duration depends on the text, voice, speech rate, and other factors. Do not estimate it from the duration of another audio recording. To synchronize text with audio playback, use subtitle timestamps and the player's actual playback position, rather than distributing text progress based only on total audio duration.
The API does not return a precomputed total audio duration. When playing audio as it arrives, the complete audio is not yet available at the start. Determine the total duration from the audio data after receiving all audio. The last subtitle's end_time may differ from the total audio duration and cannot be used as a substitute.
