AI Voice Cloning via REST API
Train custom voice models from audio samples and generate natural speech in any cloned voice. Multi-language support with emotional control.
Instant Voice Cloning
Clone a voice from as little as 10 seconds of audio. The API analyzes vocal characteristics — pitch, tone, accent, pace — and creates a reusable voice model for text-to-speech generation.
Multi-Language Voice Generation
Generate speech in cloned voices across multiple languages. The cloned voice maintains its unique characteristics while speaking in English, Spanish, French, German, Hindi, and more.
Emotional and Expressive Speech
Control the emotional tone of generated speech. Add emphasis, adjust pacing, and convey emotions like excitement, calm, urgency, or warmth through API parameters.
High-Fidelity Output
Generate broadcast-quality audio at 24kHz or 48kHz sample rates. Output in WAV, MP3, or OGG format for direct use in production applications.
Enterprise-grade voice cloning with natural prosody, emotional expression, and multi-language support.
How to Clone a Voice with Our API
Create a custom AI voice in three steps.
Step 1: Upload Voice Sample
Upload a 10-60 second audio clip of the voice you want to clone. The API accepts WAV, MP3, and OGG formats. Cleaner audio produces higher quality clones.
Step 2: Train the Voice Model
The API processes the audio sample and creates a unique voice model. Instant cloning takes seconds. For higher fidelity, you can train with longer samples for a custom model.
Step 3: Generate Speech
Send text to the API with your voice model ID to generate speech in the cloned voice. Control speed, pitch, emotion, and language through request parameters.
