Expand description

Unified trait for text-to-speech providers.

Implementors include cloud services (ElevenLabs, OpenAI, Gemini, Cartesia) and local models (MLX Kokoro, ONNX Kokoro).

Required Methods§

Source

fn synthesize<'life0, 'life1, 'async_trait>( &'life0 self, request: &'life1 TtsRequest, ) -> Pin<Box<dyn Future<Output = Result<AudioFrame, AudioError>> + Send + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Synthesize text to a single audio frame (batch mode).

Source

fn synthesize_stream<'life0, 'life1, 'async_trait>( &'life0 self, request: &'life1 TtsRequest, ) -> Pin<Box<dyn Future<Output = Result<Pin<Box<dyn Stream<Item = Result<AudioFrame, AudioError>> + Send>>, AudioError>> + Send + 'async_trait>>
where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Synthesize text as a stream of audio frames (streaming mode).

Source

fn voice_catalog(&self) -> &[Voice]

List available voices for this provider.
