Per a request from the asset_engine consumer (althing thread
01KRCF4W66X3N24B01FF2Y7V3D), and verified against the live kokoro
OpenAPI + exercised endpoints:
* kokoro: version 1 → 2; adds three fields surfaced by the upstream
schema but not previously declared:
- speed (slider 0.25–4.0, default 1.0)
- volume_multiplier (slider 0.5–2.0, default 1.0; UI-bounded
since upstream is unbounded — noted in description)
- lang_code (text, optional override of the voice-name-derived
language hint)
* kokoro-captioned: new service entry wrapping
/dev/captioned_speech. Same model + image as kokoro proper but
separate catalog entry because the response shape is structured
JSON (audio inline as base64 + word-level timestamps), not raw
audio bytes. Verified shape captured in reproducibility.notes
so future consumers don't have to re-discover it. response.type
= json (consumer renders custom: player + subtitle overlay).
* reproducibility_audit: row added for kokoro-captioned.
Deferred (separate from this commit):
- kokoro-blend-voice. /v1/audio/voices/combine returns 403 on the
default config (allow_local_voice_saving=False); even with the
flag flipped it writes to a temp dir, not /worktank/kokoro/user_voices.
The persistent blend mechanism in this fleet is
playbooks/blend-kokoro-voice.yaml. Ad-hoc blending already works
through /v1/audio/speech via the inline syntax voice="a(w)+b(w)";
consumer can surface that as a UI affordance without any
catalog change.
catalog_version stays at 1 (no field-type vocabulary changes).
JSON Schema regeneration produced byte-identical output.
