The 2026-09-06 headscale cutover retired irv-ml1's wg0 tunnel IP 10.100.79.3 (now 10.6.110.50). Repointed all LIVE canonical refs to the DNS NAME so the next move can't re-break them: homepage.href/siteMonitor labels across 25 stack composes, load-bearing env defaults (asset-engine INFERENCE_HOST, open-webui AUDIO_TTS_OPENAI_API_BASE_URL, skaldsong SKALDSONG_TTS_BASE_URL, zonos-gateway ZONOS_URL, dia), homepage services.yaml manual cards (Voice Design Studio, IRV-ML1), and servers/irv-ml1/ssh-target. Updated the stale 'WG tunnel' comment to the mesh reality. Left as-is: README curl-examples and .env.example comments (docs), and historical mentions in CLAUDE.md/persistent-memory. NOTE: applying the label repoints to the RUNNING irv-ml1 containers needs a recreate per service (labels read at creation); deployed .env values are separate from these canonical defaults.
Qwen3-TTS
Alibaba's open-weight TTS (Apache 2.0, released Jan 2026), deployed via the groxaxo/Qwen3-TTS-Openai-Fastapi OpenAI-compatible wrapper.
Server: irv-ml1 (Irvine, WireGuard-only)
Port: 8191 (container 8880)
GPUs: both exposed (NVIDIA_VISIBLE_DEVICES=all); 1.7B model
fits on either the RTX 3090 (24 GB) or A6000 (48 GB) with headroom
Image: local/qwen3-tts:v1 — built locally from a pinned git SHA
of the wrapper repo via docker buildx's git URL context
Why this stack alongside cosyvoice
CosyVoice 3 (the other stack on this host) emits Chinese-flavored phonemes when given English content. Confirmed against upstream issue FunAudioLLM/CosyVoice#1790 — closed without a fix as of 2026-04-14.
Qwen3-TTS is from the same Alibaba team but built English-first into the checkpoint: 10 languages, 97 ms streaming TTFB, instruction-driven emotional expression, voice cloning. It's the better choice for any English-narration use; keep CosyVoice 3 around for Chinese / dialect work where it shines.

Voice cloning — different shape from cosyvoice
Profile-based, not voice-id-based:
- Clone a voice via the
/voice-studioweb UI (uploads reference audio + transcript, names the profile, e.g.glados). - The wrapper writes
/root/qwen3-tts/voice_library/profiles/<name>/{meta.json,reference.wav}inside the container (bind-mounted to/worktank/qwen3-tts/voices/profiles/<name>/on the host). - Reference the profile in synthesis requests as
voice="clone:<name>".
# OpenAI-shape, English with emotion via instruction
curl -X POST http://10.100.79.3:8191/v1/audio/speech \
-H 'Content-Type: application/json' \
-d '{
"model": "Qwen/Qwen3-TTS-12Hz-1.7B",
"voice": "clone:glados",
"input": "You should leave now. Visitors are not welcome.",
"instructions": "speak with cold contempt",
"response_format": "wav"
}' \
-o glados_en_angry.wav
(Note instructions field name; OpenAI standard. Whether English
instructions actually drive emotion correctly here is the open
question this stack exists to test — see the deploy playbook's verify
section.)

Deploy
Via elway — see playbooks/deploy-qwen3-tts.yaml in the
eshpfi-management root. The playbook builds the image, ensures the
host dirs, installs compose + .env, brings up. First boot downloads
the 1.7B model from HF (~6 GB), which is the slowest step.
scripts/elway irv-ml1 --playbook playbooks/deploy-qwen3-tts.yaml
To pin a different upstream wrapper SHA, set --var sha=<new-sha> or
edit .env on the server and rebuild.
Switching to the smaller model
If 1.7B is too heavy or you need to share GPUs more aggressively:
ssh irv-ml1 '
cd /opt/docker/compose/qwen3-tts && \
sed -i "s|^QWEN3_TTS_MODEL=.*|QWEN3_TTS_MODEL=Qwen/Qwen3-TTS-12Hz-0.6B-Base|" .env && \
docker compose up -d
'
The new model auto-downloads on next start (~2–3 GB).
