"""CosyVoice3 pipeline topology (frozen).
|
|
|
|
Stage 0: Talker — text prompt → speech tokens (LLM autoregressive).
|
|
Stage 1: Code2Wav — flow-matching decoder → acoustic features → waveform.
|
|
* ``sync_process_input_func`` (``text2flow_token_only``) runs when
|
|
``deploy.async_chunk=false``: stage 1 allocates placeholder slots while
|
|
bulk tensors arrive via ``text2flow_full_payload`` on the connector.
|
|
* ``async_chunk_process_next_stage_input_func`` runs when
|
|
``deploy.async_chunk=true``: stage 0 streams codec chunks to stage 1
|
|
through the shared-memory connector.
