Trait StreamingTtsBackend 

pub trait StreamingTtsBackend: TtsBackend {
    // Required method
    fn stream(
        &self,
        request: &SynthesizeRequest<'_>,
    ) -> Result<Box<dyn Iterator<Item = Result<AudioFrame<'static>, TtsError>> + Send>, TtsError>;
}

Streaming TTS backend: text in, AudioFrame<'static> chunks out.

Extends TtsBackend with streaming support. Each chunk is a self-contained AudioFrame that can be played or forwarded immediately.

Required Methods

fn stream( &self, request: &SynthesizeRequest<'_>, ) -> Result<Box<dyn Iterator<Item = Result<AudioFrame<'static>, TtsError>> + Send>, TtsError>

Start streaming synthesis.

Returns an iterator of audio chunks. Each chunk is an owned AudioFrame at the backend’s native sample rate. The last chunk can be detected by checking the iterator exhaustion.
