- parakeet/compose.yaml: healthcheck was using curl which isn't in the
image (only wget is, via apt). 2,190 failing checks — switched to
`wget -q -O /dev/null`, container went healthy on recreate.
- qwen3-tts/.env.example: variant annotation was reversed. The upstream
wrapper's runtime error is unambiguous: voice cloning requires the
-Base variant, not -CustomVoice. Corrected the comment block and
flipped the default to Qwen/Qwen3-TTS-12Hz-1.7B-Base.
- qwen3-tts/README.md: 0.6B switch snippet now suffixes -Base too,
since plain `Qwen/Qwen3-TTS-12Hz-0.6B` isn't published on HF.
Alibaba's open-weight TTS (Apache 2.0, Jan 2026), deployed via
groxaxo/Qwen3-TTS-Openai-Fastapi wrapper. Built locally from a
pinned git SHA via docker buildx's git context — no source
vendored. 1.7B flagship model by default; 0.6B available via
QWEN3_TTS_MODEL env override.
Why we need a second TTS stack: cosyvoice 3 emits Chinese phonemes
for English content per upstream FunAudioLLM/CosyVoice#1790
(unfixed). Qwen3-TTS is from the same Alibaba team but with
English first-class in the checkpoint — 10 languages, 97 ms
streaming TTFB, instruction-driven emotion. Coexists with cosyvoice
on irv-ml1 (port 8191; cosyvoice keeps 8190).
Voice cloning shape DIFFERS from cosyvoice: profile-based, not
voice-id. Profiles live under voice_library/profiles/<name>/ and
are referenced as voice="clone:<name>".
Path layout: /worktank/qwen3-tts/{cache,voices}/, with cache excluded
from restic (regenerable from HF Hub) and voices included (cloned
profiles need original reference audio to recreate).
playbooks/deploy-qwen3-tts.yaml: 10 steps + 5 verify, idempotent;
the wait step polls /health for up to ~10 min to absorb first-run
model download.
Stack only — restic profile update for /worktank/qwen3-tts/voices/
to follow when this is empirically validated against the GLaDOS
voice (the "did Qwen inherit the Chinese-bias bug?" question).
