dankvoice

agent/extensions/dankvoice.ts adds cloned-voice speech to the interactive harness: /say opens the options menu, /say <text> speaks through the speakers and /say on narrates the assistant's final answer after every turn, all served by frank-tts (Dankclaw :7772, the speech model role in agent/models.yml).

Why it exists

Nothing built into the harness can pronounce Frank's cloned voices.

Surface	Engine	Verdict
TUI speak-aloud (speech.enabled, speech.voice)	bundled Kokoro ONNX worker, synthesizeStream(voice, speed, signal)	Kokoro voice enum only; never consults models.yml or the speech role
omp say [TEXT]	same local backend (--model = local model key)	omp say --voice narrator1 "test" → error: Expected --voice to be one of: af_heart, af_bella, af_nicole, af_kore, af_sarah, am_michael, am_fenrir, am_puck, bf_emma, bm_george, bm_fable (verified 2026-10-18)
tts tool / xd://tts device (modelRoles.speech)	frank-tts over OpenAI /v1/audio/speech	cloned voices work, but only as a file — nothing plays them

dankvoice is not a patch to that vocalizer (harness code, not ours); it is a second transport that happens to speak, so Kokoro stays available for quick local speech and the cloned voices carry the real narration.

Commands

Command	Effect
/say | /say menu	options menu (ctx.ui.select): auto-speak toggle, voice, output device, player, spoken cap, test phrase
/say <text>	synthesize once and play; interrupts whatever is playing
/say on | /say off	arm/disarm auto-speak of the assistant's final text at agent_end; the footer shows 🔊 <voice> while armed
/say voice <name>	pick a voice; an empty name defers to the server's own default
/say voices	list what frank-tts reports
/say stop	cut the current utterance
/say status | /say help	endpoint, voice, player, device, cap

Menu choices persist to ~/.omp/cache/dankvoice.json (runtime state, never tracked); the environment overrides the file, the file overrides defaults. "Speak a test phrase" synthesizes a short line through the current voice, player and device — the audible proof whenever a session "has say on" but stays silent.

Auto-speak is skipped in print/json mode so benches and pipelines stay silent. Markdown is stripped before synthesis — fenced code is dropped, links collapse to their label, bullets and table pipes disappear — and the utterance is truncated at a sentence boundary inside the cap.

Endpoint resolution

The base URL is read from agent/models.yml, from the provider block whose model row carries api: openai-speech — the same row the speech role resolves, so no host address and no credential appears in this file. From baseUrl: http://192.168.0.143:7772/v1 it derives POST …/v1/audio/speech, GET …/v1/audio/voices and GET …/health.

Environment	Default	Meaning
DANKVOICE_URL	models.yml	speech base URL (…/v1), bypasses the YAML read
DANKVOICE_MODEL	the id in that block (frank-tts)	model named in the request body
DANKVOICE_CONFIG	~/.omp/cache/dankvoice.json	persisted menu choices (voice, player, sink, cap, auto)
DANKVOICE_VOICE	empty (server default)	default voice name
DANKVOICE_AUTO=1	off	start with auto-speak armed
DANKVOICE_MAX	700	spoken characters per utterance
DANKVOICE_PLAYER	detect	player binary, skipping detection
DANKVOICE_MODELS	~/.omp/agent/models.yml	YAML to read the endpoint from

Player detection order is pw-play → paplay → ffplay (PipeWire first: the workstations run WirePlumber). A saved output device routes the player explicitly — pw-play --target <sink> or paplay --device=<sink>; ffplay has no device concept and ignores it — while an unset device leaves the player's own default. Sinks are enumerated with wpctl list audio sinks; if wireplumber is unreachable the menu offers only "system default". Each utterance is written to $TMPDIR/dankvoice-*/say-<ms>.wav and the file plus its directory are removed when the player process exits.

Verified facts (2026-10-18)

• Extension discovery — any .ts file in ~/.omp/agent/extensions/ loads at startup: a probe file there printed loaded 2026-10-19T02:36:55Z from a fresh omp -p run. omp --help documents --no-extensions (discovery off, explicit -e/--extension and --hook still load) and plugin install|link.
• Endpoint — resolving the live agent/models.yml yields speechUrl http://192.168.0.143:7772/v1/audio/speech, voicesUrl …/v1/audio/voices, healthUrl …/health, model frank-tts.
• Roster — GET /v1/audio/voices answers the bare JSON array ["narrator1","narrator2","narrator3"]; /health answers {"status":"ok","backend":"omni-http","voices":[…]}. GET /v1/voices and GET /v1/models are 404 on this shim, and an unknown voice answers 400 unknown voice 'zzz'; available voices: … with available_voices in the body — which is the fallback the extension uses if the roster route ever disappears.
• Omitting voice is legal — frank-tts fills its DEFAULT_VOICE since the 2026-10-18 voice-pack work, so an unset voice synthesizes instead of failing.
• Speech — /say "dankvoice live smoke test" produced a 99,884 B / 2.08 s WAV and /say voice narrator2 + /say "cloned voice check" a 69,164 B / 1.44 s WAV (durations from ffprobe), each handed to the player; temp directories were gone afterwards.
• Auto-speak — verified in a real TUI session: /say on armed the footer (🔊 narrator1), the next finished turn synthesized and played the answer (1.20 s WAV), and an unknown voice name answers with the roster instead of speaking. An agent_end carrying willContinue (the harness scheduled an auto-retry) is never narrated — only the terminal settle speaks.
• Menu — verified via driver scenarios 2026-10-18 (Refs #23): the menu lists auto-speak/voice/device/player/cap/test-phrase; a voice chosen in the menu is used by later utterances and survives a fresh load via the settings file; a device chosen in the menu appears in the player invocation as --target <sink>.

Limits

• The TUI's own speak-aloud feature still narrates in Kokoro: its voice list is a compile-time enum in the harness bundle, and no setting routes it to frank-tts. Cloned voices live only on this file-producing/speaking path and on the tts tool. See Handy for the STT half.
• agent_end narrates the final message text only — mid-turn tool chatter is never spoken.
• frank-tts is LAN-only: no Caddy vhost fronts :7772, so this extension is usable on the home network.
• Deployment, packs and the voice registry are owned by the serverAppConfigs repo (serverAppConfigs-docs/Dankclaw/Frank TTS.md), not by this one.
