Adom TTS: Text to Speech

Default surface is hydrogen webview; if the user seems to be+  on a phone via adom-rc, hydrogen still works (audio plays through phone).+---++# adom-tts — shared TTS CLI, Tier B++`adom-tts` is the Adom-wide text-to-speech CLI. It shells every synthesis+call through the `service-tts` container (edge-tts + `en-US-AndrewNeural`+by default) so:++1. **Adom pronunciation overrides auto-apply server-side.** Terms like+   `adom-tsci`, `aci`, `instapcb`, `kicad` come out phonetically correct+   without the caller pre-phoneticizing. 18 overrides loaded from+   [tts-pronunciation](../tts-pronunciation/SKILL.md).+2. **Source-hash cache.** Repeat synthesis of the same `(text, voice, rate)`+   returns cached bytes instantly. Demo iteration loops save real time.+3. **Adom-owned URL.** Backend (edge-tts → piper → Azure direct → ElevenLabs)+   is swappable without any caller changes.++Default voice is `en-US-AndrewNeural` per approval. Service lives at+`https://adom-tts-f84dy9x2ezq9.adom.cloud`; CLI bakes it in at build time.++## When to reach for this skill (besides obvious "make me an mp3" asks)++**Hands-free / driving mode.** If the user says any of "I'm driving", "can't read the screen", "read it to me", "read it out loud", "read me your answer", "I'm in the car", "narrate the answer", "tell me out loud", "while I drive" — they CANNOT see your text response. The right move is:++1. Compose what you would have written as a normal reply (concise, ~30–60 seconds spoken).+2. Pipe it straight into `adom-tts say "..." --out /tmp/answer.mp3 --play`.+3. The reply plays automatically; you don't need a separate "here's a summary" text response on top of it (the user can't see it anyway).++This is the canonical drive-mode pattern. Memorize it. The user's literal words won't always say "TTS" — they'll say "I'm driving, just read me your answer." That IS the trigger.++## Use++**If the user wants to HEAR the audio, use `--play`. Don't author a custom autoplay HTML, don't `python3 -m http.server`, don't create a port mapping. `adom-tts` ships a built-in auto-player.**++```bash+# Synthesize and AUTO-PLAY (the common case).+# Detaches; CLI returns immediately.

Hydrogen webviews have the same constraint.+- ❌ Custom HTML with base64-inlined mp3 + `data:` URL — past 2 MB this hits Chrome's URL length limit.+- ❌ `adom-cli carbon containers port-add` — provisions a permanent `*.adom.cloud` subdomain for a one-shot, total overkill.+- ✅ Just use `--play`. The binary handles the surface, the URL, and cleanup.++`say` emits `→ <path> (<bytes>, cache=hit|miss, hash=<prefix>)` — scripts+can parse `cache=hit` to detect re-renders.++When `--play` is omitted, `say` also emits stderr hints reminding the AI of the auto-player. Silence them with `ADOM_TTS_NO_HINTS=1` for already-stable scripts.++Other commands:++```bash+adom-tts voices          # GET /tts/voices (edge-tts list as JSON)+adom-tts pronunciations  # GET /tts/pronunciations (the override table)+adom-tts health          # service + edge-tts version+adom-tts config          # which URL is this binary hitting?+adom-tts config --show   # also dump the resolved play surface + config path+```++## Drive mode (hands-free auto-player)++You wrote an mp3 — now play it.

The container's `$VSCODE_PROXY_URI` wraps that port into+a Cloudflare-routable URL. The chosen surface (Hydrogen webview tab or+pup browser window) navigates to that URL — same plumbing, no port+mappings, no clip-size limits, no base64 URL bloat.++**Surface (Hydrogen vs pup).** Picked from this precedence chain:++```+--surface hydrogen|pup   →   $ADOM_TTS_SURFACE   →   ~/.adom/tts/config.toml   →   "hydrogen" (default)+```++Pin a default in `~/.adom/tts/config.toml`:++```toml+[play]+surface     = "pup"        # or "hydrogen"+pup_session = "adom-tts"+pup_profile = "adom-tts"+```++Default is `hydrogen` (always available inside the container; pup needs+a desktop Chrome session). Per the pup skill's "pick ONE surface" rule,+there is intentionally no `both` option.++**Tab name.** Hydrogen tabs are titled `"TTS Player"` (distinct from the+playground's `"TTS Playground"`). Repeat `play` calls open new tabs;+close stale ones with `adom-cli hydrogen workspace close-panel <id>`.++**For AIs.** When the user says "read me X", "play this", "make audio+and play it" — go straight to `adom-tts say "X" --out /tmp/x.mp3 --play`.+Don't write an autoplay HTML file. Don't create a port mapping. The+detached child handles the surface and self-shuts down on the audio's+`ended` event (or after a 5-minute cap).++## Install (Tier B via wiki)++```bash+curl -fsSL https://wiki-ufypy5dpx93o.adom.cloud/static/apps/adom-tts/adom-tts \+  -o /tmp/adom-tts && chmod +x /tmp/adom-tts \+  && sudo install -m 0755 /tmp/adom-tts /usr/local/bin/adom-tts \+  && adom-tts install \+  && adom-tts health+```++## Who should use this (and how)++- **demo-recording** — replace `edge-tts --voice ...` invocations with+  `adom-tts say`. Cache hit + phonetic-correct Adom terms for free.+- **aci voice** — backend precedence was updated to prefer `adom-tts` over+  direct `edge-tts`. Users don't have to do anything; `aci voice say`+  routes through `adom-tts` if it's on PATH.+- **any future tour/walkthrough/voiceover** — same pattern: `adom-tts say`,+  don't invoke edge-tts directly.++## Why not invoke edge-tts directly?++Because:++- Every consumer has to know every pronunciation override (or get them+  wrong). Server-side application fixes this once.+- Repeat renders cost real time (+ Microsoft endpoint bandwidth). A+  source-hash cache makes the 2nd + N-th call free.+- When Microsoft changes the edge-tts endpoint (they have; will again),+  every consumer breaks in parallel. One server-side swap fixes everyone.+- Voice consistency: Andrew Neural is approved once in the `Adom` context;+  every call through adom-tts gets that default.++## Related skills++- [tts-pronunciation](../tts-pronunciation/SKILL.md) — the canonical+  phonetic-override table (loaded by service-tts at startup).+- [demo-recording](../demo-recording/SKILL.md) — top consumer.+- [service-kicad](../service-kicad/SKILL.md),+  [step2glb](../step2glb/SKILL.md) — sibling Tier B services + CLIs.++Canonical source: `adom-inc/service-tts` repo + `adom-inc/adom-tts` repo.
