By name: speaker-recognizer
description: Self-enroll a voice for speaker recognition. Activate ONLY when (a) a mic Unknown Speaker: turn carries a clear self-introduction ("I'm X", "my name is X", "tôi là X"...), (b) prior same-tag [voice:voice_N] turns can be combined with a now-named turn, (c) a Telegram voice-note carries an intro, OR (d) the user asks to list / forget / identify voices. Do NOT activate on bare Unknown Speaker: turns with no name and no prior same-tag history — those need only a short ack. Self-enrollment only.
Speaker Recognizer
Each mic transcript is prefixed Speaker - Name: when recognized, or Unknown Speaker: [voice:voice_N] ... (audio save[d] at <path>...) otherwise. The audio path is the WAV of whoever spoke this turn — use it (with paths from prior same-tag turns when needed) to enroll on POST /speaker/enroll.
Self-enrollment only — never enroll one person's voice under another person's name.
Decision matrix — pick ONE action per turn
| Signals in current turn | Prior same-tag turns? | Action |
|---|---|---|
Unknown Speaker: + path + name + ≥25 words |
— | Enroll now with current path only. |
Unknown Speaker: + path + name + <25 words |
≥1 prior path same [voice:N] |
Enroll now with all same-tag paths (oldest→newest). |
Unknown Speaker: + path + name + <25 words |
none | Ask one follow-up: "say your name + ~25–30 words". |
Unknown Speaker: + path + NO name + <25 words |
none | Ask one follow-up. |
Unknown Speaker: + path + NO name |
≥1 prior path same [voice:N] (still no name) |
Reply with a SHORT ack ("Mm, nghe rồi" / "Got it"). NEVER NO_REPLY. Don't re-ask. |
Speaker - <Name>: |
— | Already identified — skill not needed. |
| "who do you know?" / "list voices" | — | GET /speaker/list. |
| "forget my voice" / "remove Alex" | — | POST /speaker/remove. |
| Telegram voice note + intro | — | Convert to WAV + enroll with Telegram fields. |
| Telegram voice note + "who is this?" | — | POST /speaker/recognize. |
When in doubt → see reference/enroll-flows.md. All curl + error handling → reference/api.md.

Hard rules
- Self-enrollment only — "this is my friend Bob" → refuse politely; Bob must speak himself.
- Lowercase normalized name — same
nameasface-enrollfor the same person (/root/local/users/<name>/is shared). - Minimum voice for one-turn enroll: ~25 words (aim 25–30) OR combine with prior same-tag turns to ~5–10s total.
- Cluster claim is automatic — pass any path inside
voice_<N>/and the server pulls every sibling WAV. One path is enough. - Two-turn path mapping —
<pathA>= turn BEFORE follow-up,<pathB>= turn AFTER. Never swap. - Telegram audio must be 16 kHz mono WAV before enroll — convert with
ffmpeg -ar 16000 -ac 1; same folder as source. Skip if already.wav. /speaker/identity(not re-enroll) when only linking Telegram info to an existing mic profile.- Don't spam "who are you?" — at most once per cluster, and include the "25–30 words" guidance in the same message.
- Never go silent on Unknown Speaker fragments — when no name and you've already asked, emit a short ack. NO_REPLY is forbidden.
- Confirm every enroll AFTER the API returns ok.
- Don't narrate technical details — no "base64", "ffmpeg", "POST /speaker/enroll".
- Never write files directly — always use the HTTP API.
