Events
| name | description | known nodes that generate this event |
|---|---|---|

A TTS Synthesis audio can be generated from any event that is text based. Users can also generate their custom event that has Data.Text and send it through the Entry, or External Relay nodes. |
SR Http, SR WebSocket, Translate |
Outputs
Audio
Synthesized speech is sent to output
Audio format is 16-bit PCM at the project’s audio sample rate.
Audio is sent without a WAV header; downstream nodes should respect the HasWaveHeader = false flag
Events
| name | description |
|---|---|
| Start of TTS Fragment | Sent just before a TTS audio fragment is written to the Audio output. Contains metadata about the fragment. This event includes Data.HasWaveHeader = false . |
| End of TTS Fragment | Sent just after a TTS fragment has been fully written to the Audio output. |
Remarks
Custom TTS Event
A sample tts-request event would look as follows.
{
"Event": {
"Name": "Custom TTS Event",
"Data" : {
"Text": "hello world"
}
}
}
Data.Text: The text that will be synthesized.
Sending Custom Events to Projects
To learn more about sending Events to projects, you can check the HTTP and External Relay pages.
