Create a Custom ElevenLabs Voice

Clone a voice from sample recordings of one speaker and get back a permanent voice_id usable anywhere a premade voice ID works (e.g. Text-to-Speech). Request Body:

Field	Type	Required	Description
`samples`	array of strings	Yes	URLs of audio recordings of one speaker. More recordings of the same person produce a better voice. Max 25 samples, max 25 MB each. Direct-download URLs only (no redirects or link shorteners). Formats: mp3, wav, ogg, opus, m4a, flac, webm
`name`	string	No	A label for your own reference. Not an identifier

curl -X POST https://api.unifically.com/v1/resources/elevenlabs/voices \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "samples": [
      "https://cdn.example.com/recording1.mp3",
      "https://cdn.example.com/recording2.wav"
    ],
    "name": "Podcast Talker"
  }'

Response:

{
  "success": true,
  "data": {
    "voice_id": "NLQzxuY9B0rsgFcPKVW4",
    "name": "Podcast Talker",
    "samples": ["https://cdn.example.com/recording1.mp3", "https://cdn.example.com/recording2.wav"]
  }
}

Store the voice_id — it is returned only once. There is no endpoint that lists custom voices, by design (voice IDs are private to whoever holds them).

The voice is permanent: a copy of your samples is kept, so it keeps working even after your original URLs go offline. Voice IDs from your own ElevenLabs account cannot be used here — create the voice through this endpoint instead.

Get Suno Voice Verification Phrase

Generates a verification phrase for Suno voice creation. Query Parameters:

Parameter	Type	Required	Description
`language`	string	No	Language code for the phrase. Available: `zh`, `en`, `es`, `fr`, `pt`, `de`, `ja`, `ko`, `hi`, `ru`

curl https://api.unifically.com/v1/resources/suno-ai/voice/verification-phrase?language=ru \
  -H "Authorization: Bearer YOUR_API_KEY"

Response:

{
  "success": true,
  "code": 200,
  "data": {
    "phrase_id": "ea748c01-6257-45ff-a037-c8657ff5c09d",
