Create Voice (ElevenLabs)

Create a new custom voice clone using ElevenLabs Instant Voice Cloning (IVC).

Requirements:

• Provider must be an ElevenLabs provider
• Audio file must be at least 30 seconds (recommended: 60-120 seconds)
• Supported formats: MP3, WAV
• Background noise removal is automatically enabled

Audio Quality Guidelines:

• Sample rate: 44.1 kHz recommended

Note: After creation, it may take a few moments for the voice preview to be generated by ElevenLabs. The voice can be used immediately for text-to-speech.
