Create Custom Voice

Create a cloned voice from an audio sample:
Voice cloning requires a 30+ second audio sample with clear speech.
Each workspace can keep 1 instant voice on Free, Starter and Flow, and 10 on Creator and Pro. Over the limit the tool returns an error with code VOICE_LIMIT_REACHED; delete a voice or upgrade.

Voice Limits and Professional Voices

These tools are read-only and take only an optional response_format (markdown or json).
  • sixtydb_get_voice_quota: how many instant voices (1 on Free/Starter/Flow, 10 on Creator/Pro) and professional voices (Creator 2, Pro 5) you have used and can still create.
  • sixtydb_list_professional_voices: your professional voices with their status: training, private, in marketplace review, live, rejected or failed.
  • sixtydb_get_marketplace_eligibility: whether you can submit a voice to the marketplace, and what is missing (plan, KYC tax form, bank details).
Professional voices can’t be created through MCP: they need a live recording for verification, so create them in the app under Voice Library → Professional voice. KYC and bank details are added in the app under Payouts.
