Overview
End-to-end process for creating a custom voice clone from audio samples using the ElevenLabs Instant Voice Cloning (IVC) API, then using it for text-to-speech generation.
Description
This workflow covers the process of cloning a voice from one or more audio sample files using the ElevenLabs Instant Voice Cloning feature. Once a voice clone is created, it can be used with any of the TTS models for speech generation. The process involves uploading audio samples, providing metadata (name, description), and receiving a voice object with a unique ID that can then be used for text-to-speech conversion.
Usage
Execute this workflow when you need to create a custom voice that sounds like a specific person or character, given audio recordings of that voice. This applies to content personalization, brand voice creation, character voiceover for games or animations, and accessibility tools requiring a familiar voice.
Execution Steps
Step 1: Client Initialization
Create an ElevenLabs client instance with an API key. Voice cloning requires authenticated access to the API, so the API key must be provided either directly or via the ELEVENLABS_API_KEY environment variable.
Key considerations:
- Voice cloning is a paid feature that requires an active ElevenLabs subscription
- API key authentication is mandatory for voice creation endpoints
Step 2: Audio Sample Preparation
Prepare audio sample files that contain clear recordings of the target voice. Samples should be clean, with minimal background noise, and representative of the voice characteristics to be cloned. Multiple samples can be provided to improve clone quality.
Key considerations:
- Multiple samples (recommended 3+) improve voice clone quality
- Supported formats include MP3, WAV, and other common audio formats
- Audio should be clean speech without music or excessive background noise
- Samples should represent the natural speaking style desired for the clone
Step 3: Voice Clone Creation
Call the voices IVC create endpoint with the voice name, optional description, and audio sample files. The API processes the samples and creates a new voice entry. The response includes a Voice object with the unique voice_id needed for subsequent TTS calls.
Key considerations:
- The name parameter is required and should be descriptive
- The description parameter is optional but helps organize voices in the library
- File paths are passed as a list of strings pointing to local audio files
- The created voice appears in the voices library and can be managed via the API
Step 4: Speech Generation with Cloned Voice
Use the newly created voice for text-to-speech generation by passing the voice_id from the clone response to any TTS endpoint (batch convert, streaming, or realtime). The cloned voice works with all available TTS models.
Key considerations:
- The cloned voice_id can be used with any TTS model (v3, Multilingual v2, Flash, Turbo)
- Voice settings (stability, similarity boost) can be adjusted to fine-tune output quality
- The cloned voice persists in the account and can be reused across multiple requests
