TTS development moves to a dedicated repo (~/development/tts-stack) so a separate
agent can own tuning/dev. Mirrors the chatterbox-fast extraction:
- stacks/dots-tts/ reduced to a pointer README (code/Dockerfile/compose/tests/env
now canonical in tts-stack).
- voices/ canonical corpus moved out to tts-stack/voices/. Blast-radius checked:
no eshpfi playbook/script reads the corpus (other voices/ refs are unrelated
host paths under /worktank/...).
- persistent-memory updated: TTS dev extracted + stood down; reverses the earlier
"corpus home = eshpfi voices/" call.
The ~15 experimental TTS compose wrappers stay here as reference (catalogued in
tts-stack/KNOWLEDGE.md). Live service on irv-ml1:8198 is unaffected (runs from a
copy on the host).
dots' prosody honors a pause only for ellipsis (~+0.43s) and period (~+0.3s);
comma/semicolon/colon/dash all run flat (~+0.03s vs no-punct), measured via a
duration-over-N-runs pause probe against the live service. Two sub-causes for
the flat clause reads: em-dashes regressed in v2 (the —→- fold made them read
as word-joiners), and semicolons were never honored by dots at all.
Operator ruled ellipsis "too much" → map semicolon, clause colon, and em-dash
to a period in _sanitize (believable ~0.3s clause pause). Guards, pinned by
tests: digit-guarded colon so times (3:45) and ratios (2:1) keep their colon;
en-dash kept folding to hyphen so numeric ranges (10–20) don't become "10.20";
a genuine ellipsis retains its strong pause.
Deployed to irv-ml1:8198 as local/dots-tts:v3 via the redeploy2 build →
:8199-test → pause-gate → cutover pattern (gate measured +0.427s, live healthy).
Curly apostrophes (ratatoskr's LLM emits typographic punctuation) made dots
mispronounce contractions ("Donut's"->"donut ess"); fold curly->ASCII before
synth, keep normalize_text on. Add server-side sentence-chunking so long turns
stop truncating at dots' ~40s single-generate cap (verified full 160s Zev).
Dockerfile: pin dots.tts==0.2.1 + torch/torchaudio==2.8.0 (upstream constraints
now pin a phantom gradio==6.17.0; float torchaudio->2.11.0 crashes the load).
