Documented steps
Create an API key in the ElevenLabs dashboard (Settings > API Keys). You must have the rights to clone the voice you are uploading.
Gather sample audio of the target voice. The docs note that under two minutes of audio can already produce a usable instant clone; more varied samples improve consistency.
POST multipart/form-data to https://api.elevenlabs.io/v1/voices/add with header xi-api-key: <API_KEY>.
Add required field name — the label shown in the voice dropdown.
Attach one or more samples under required field files.
Optionally add description, labels (a map keyed by language, accent, gender or age), and remove_background_noise=true to run audio isolation before cloning (default false).
On success (200) read voice_id and requires_verification from the response.
If requires_verification is true, complete the voice-captcha verification flow before the clone can be used for synthesis.
Use the new voice_id as the voice parameter on text-to-speech calls.
To browse the library, GET https://api.elevenlabs.io/v2/voices with the xi-api-key header. Note this listing endpoint is v2, not v1.
Filter and page with page_size (default 10, max 100), search, voice_type (personal/community/default/workspace/saved), category (premade/cloned/generated/professional), sort, sort_direction and next_page_token. The response carries voices[], has_more, total_count and next_page_token.
To remove a voice, DELETE https://api.elevenlabs.io/v1/voices/{voice_id} with the xi-api-key header; success returns {"status":"ok"}.
Verify against the official docs: https://elevenlabs.io/docs/api-reference/voices/ivc/create , https://elevenlabs.io/docs/api-reference/voices/search and https://elevenlabs.io/docs/api-reference/voices/delete
Known gotchas
Instant Voice Cloning (IVC) and Professional Voice Cloning (PVC) are different products: PVC requires a Creator plan or above and roughly 30 minutes of source audio, versus IVC's much smaller sample requirement. Do not size a project against the wrong one.
A successful create can still return requires_verification=true, meaning the voice cannot synthesize until the captcha/ownership step is completed — automation that ignores this field will fail at the first TTS call.
Listing voices is /v2/voices while create and delete remain /v1 — mixing the versions produces confusing 404s.
Auth is xi-api-key across all voice endpoints, never Authorization: Bearer.
Cloning a voice without the speaker's authorization violates the ElevenLabs terms and AI safety policy; responsibility sits with the uploading account.
The create reference does not document a max sample file size or an explicit supported-format list; the worked example uses mp3, so validate your own formats before bulk runs.
Deleting a voice is immediate and cannot be undone — capture voice_id values before cleanup jobs.
