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
- Check the source file is local and intentionally provided.
- Confirm rights for both sides:
- source recording copyright and speaker authorization
- target voice consent or provider-licensed voice
- Refuse public figure or copyrighted character imitation.
- Use
audio_provider_capabilities if conversion availability is uncertain.
- Call
voice_convert with source_audio, voice, optional output_path,
and any supported provider controls.
- 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.
Output contract
Return:
- provider
- target voice
- output path
- mime type
- playable audio artifact status
- rights/consent summary
- target language / locale assumption
