Trait for pluggable TTS backends.

Required Methods§

Source

fn name(&self) -> &str

ModelProvider identifier (e.g. "openai", "elevenlabs").

Source

fn synthesize<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, text: &'life1 str, voice: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<u8>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Synthesize text using the given voice, returning raw audio bytes.

Source

fn output_format(&self) -> &str

The audio container/format of the bytes returned by synthesize (e.g. "opus", "wav", "mp3"). Channels use this to pick the correct upload MIME type and Telegram send method — only opus/ogg is a true voice note.
