- Add run_customvoice_server.py: OpenAI-compatible TTS server for Qwen3-TTS
CustomVoice models with speaker-based voice selection and per-request
language/instruct/max_new_tokens overrides
- Add customvoice_voices.json: voice config for 9 built-in speakers across
English, Chinese, Japanese, and Korean
- Add benchmark_api.py: API benchmarking tool reporting TTFA, total time,
RTF, and speed multiplier across short/medium/long sentences
- Refactor run_voicedesign_server.py: extract _request_generation_params()
helper, add per-request language/instruct/max_new_tokens override support,
and wire DEFAULT_MAX_NEW_TOKENS to --max-seq-len arg
- Add faster-qwen3-tts.code-workspace for VS Code project config

- generate_voices.py: scan /config/speakers and /voices recursively,
support .ogg and .m4a (M4A auto-converted via ffmpeg), sanitise voice IDs
- auto_transcribe.py: scan both host paths recursively, support all formats,
use parakeet-asr on port 8010
- docker-compose.yml: mount /home/sparky/Projekte/TTS_Voices/speakers as
/voices, add faster-qwen3-tts-voicedesign service on port 8021
- run_voicedesign_server.py: OpenAI-compatible server for VoiceDesign model
- voicedesign_voices.json: 8 British/German VoiceDesign voices

- run_server.py: warm up CUDA graphs at server startup via lifespan
event so the first real request does not pay the 7-8s graph-
compilation penalty; uses modern lifespan API instead of deprecated
on_event
- generate_voices.py: set chunk_size=4 per voice so streaming clients
receive first audio after ~333ms instead of ~1s
- docker-compose.yml: add --max-seq-len 2048 (halves static KV cache,
reduces VRAM and graph-capture time)
- config/benchmark_api.py: new script to measure TTFA, RTF and speed
against the live API endpoint

Run Qwen3-TTS with CUDA graph acceleration on NVIDIA DGX Spark
(ARM64 / SM 121 / CUDA 13) as an OpenAI-compatible TTS API server.
- Dockerfile targeting nvidia/cuda:13.0.2-base-ubuntu24.04 with ARM64 cu130 PyTorch wheels
- Patch for max-seq-len support to handle long reference audio without crashes
- OpenWebUI + SillyTavern compatible API endpoints (/v1/models, /v1/audio/voices, /speakers)
- Voice management: auto-generate voices.json from speaker reference audio files
- Auto-transcription helper script for generating reference text from audio
