voice-clone-lab

Creates a reusable provider voice from a local sample. OpenRouter may help summarize the request or produce labels, but cloning must use the direct audio provider through voice_clone.

Request triage

Before calling tools, extract these fields from the user request:

• sample path and whether the file is local, intentional, and user-provided
• speaker identity class: self, employee/team member, private person, public figure, fictional character, or unknown
• consent metadata: speaker, consent, sample source, permitted use, requested by, retention expectation, and whether commercial use is allowed
• target use: TTS narration, IVR, dubbing, training content, or internal demo
• target language, target locale, and desired locale-appropriate accent

OpenRouter can summarize consent text or label a voice, but it is not an audio provider and cannot replace explicit consent.

Consent-first workflow

1. Confirm the sample audio path is local and intentionally provided.
2. Require consent_metadata before calling voice_clone.
3. Include at minimum:
   • speaker
   • consent: true
   • sample_source
   • permitted_use
   • requested_by
4. Reject or stop when consent is missing, vague, or contradicted by the request.
5. Call audio_provider_capabilities if cloning availability is uncertain.
6. Call voice_clone with the sample, name, description, and consent metadata.
7. Return the created voice ID and the allowed usage summary.

Tool-result handling

• If voice_clone returns status=ok, return the voice ID first, then the consent summary, intended locale/accent, and any sample-quality warning.
• If it returns consent_required, do not proceed with a workaround. Ask for the missing consent metadata in one concise question.
• If the provider returns not_available, quote the note and distinguish disabled provider, key/quota limits, feature gating, and sample format issues.
• Never suggest scraping, downloading, or extracting third-party voice samples as a fallback.

Rights and copyright guard

• 授权 is mandatory. The speaker must own or control the voice sample and agree to cloning for this use.
• Copyright / 版权: do not use copyrighted recordings, film/TV/game clips, music stems, interviews, or scraped audio unless the user states they have rights.
• Public figure policy: do not clone or imitate a public figure, celebrity, politician, influencer, actor, singer, or fictional character voice.
• Do not help bypass provider safety checks or watermark/disclosure duties.
• Store only the returned provider voice ID and consent summary in ordinary output; do not duplicate raw sample audio.

Locale and accent quality notes

Ask which target language and locale the cloned voice will be used for. A clone works best when the sample matches the desired locale-appropriate accent.

• Chinese neutral narration: use clean 普通话 sample audio.
• American English: use clean en-US sample audio.
• British English: use clean en-GB sample audio.
• Japanese/Korean/French/German/Spanish/etc.: use samples spoken in that target language, not an English sample repurposed cross-lingually.
• Strong dialect, code-switching, room echo, music, or singing can produce odd accent transfer in later TTS. Recommend 30-90 seconds of dry speech when possible.

Output contract

Return:

• provider
• voice ID
• voice name
• consent summary
• allowed use
• target language / locale assumption
• warning if the source sample quality may harm target-language accent quality
