voice-conversion-studio

Converts an existing local recording into a target voice using the configured audio provider. OpenRouter can assist with planning or file naming, but the conversion itself must use voice_convert.

Request triage

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

• source audio path and whether it is local, intentional, and user-provided
• source rights: speaker consent and recording copyright
• target voice: provider-licensed voice, cloned voice ID, or user-provided voice ID
• target language, target locale, desired accent, emotion, pace, and output format
• output expectation: quick conversion sample, final asset, or multiple takes

OpenRouter can help summarize or translate instructions, but it is not an audio provider and cannot authorize voice identity use.

Required workflow

1. Check the source file is local and intentionally provided.
2. Confirm rights for both sides:
   • source recording copyright and speaker authorization
   • target voice consent or provider-licensed voice
3. Refuse public figure or copyrighted character imitation.
4. Use audio_provider_capabilities if conversion availability is uncertain.
5. Call voice_convert with source_audio, voice, optional output_path, and any supported provider controls.
6. Return the result as a playable audio artifact when the surface supports it.

Preview-first

When source quality, accent transfer, or target voice fit is uncertain, convert a short sample before processing a full recording. Recommend re-recording or cleaning the source if the preview contains room echo, background music, strong dialect mismatch, or heavy code-switching.

For multilingual conversion, avoid using a target voice that does not naturally support the target language. A short preview is the fastest way to catch odd accent transfer before spending quota on the whole asset.

Tool-result handling

• If voice_convert returns status=ok, return the playable artifact/path first, then target voice, mime type, and rights summary.
• If it returns consent_required, ask for source and target consent metadata instead of attempting a different voice identity.
• If it returns not_available, quote the note and distinguish provider setup, feature gating, key/quota limits, file format, and source path issues.

Rights and copyright guard

• 授权 is required for the source speaker and target voice.
• Copyright / 版权: do not convert songs, movie lines, podcasts, audiobooks, lectures, interviews, or game/animation dialogue unless the user says they have rights.
• Public figure policy: do not convert a recording to sound like a public figure, celebrity, actor, singer, politician, influencer, or fictional character.
• If the user asks for a risky identity target, offer a non-identifying target: "mature calm Mandarin narrator", "bright young commercial voice", etc.

Locale and accent quality notes

For voice conversion, first identify the target language and locale. The source recording and target voice should be compatible with the desired locale-appropriate accent.

• Chinese neutral narration: prefer clean 普通话 source and target voice.
• English: preserve requested locale such as en-US, en-GB, en-AU, en-IN, or en-SG.
• Japanese/Korean/French/German/Spanish/etc.: prefer source/target voices that naturally support that language.
• Strong dialect, background music, reverberation, and heavy code-switching can cause odd accent transfer. Recommend re-recording a short, dry sample before converting a whole script.
