feat: add streaming support to /tts endpoint via stream param#140
Merged
Conversation
Add stream: bool = False to CustomTTSRequest. When true, custom_tts_endpoint returns a StreamingResponse with a streaming WAV header (0xFFFFFFFF size) and PCM chunks yielded as each text chunk is synthesized. Crossfading between chunks reuses existing _crossfade_with_overlap helper. Non-streaming path unchanged.

Merged, thanks. Clean implementation: opt-in parameter with a safe default, gated streaming branch, existing code path untouched. Appreciate the contribution. |
