The VoiceClone server was using non_streaming_mode=False, a mode designed
for streaming LLM->TTS pipelines. In that mode only one text token enters
the model's KV cache during prefill; the rest feed via trailing_text_hiddens
at one step per codec frame. For a 54-word paragraph this provides only ~4s
of text guidance for ~18s of speech — 77% generated with no text conditioning.
Without text context the model free-runs and drifts, sometimes changing gender.
Fix: switch to non_streaming_mode=True (already the default for VoiceDesign
and CustomVoice) so the full text is in the prefill throughout generation.
Also lower default temperature 0.9->0.8 and add top_p=0.9 to reduce
accumulated sampling noise over long runs. Temperature, top_k, and top_p
are now configurable per voice in voices.json.
- patches/openai_server.patch: updated for new upstream HEAD; both streaming
(WAV/PCM) and non-streaming (MP3) paths now use non_streaming_mode=True
- config/run_server.py: align warmup call to non_streaming_mode=True
- README.md: bump image tags v4->v5, add changelog section
- Version: v5
