Voice Cloning

Definition

Voice cloning creates a synthetic replica of a person's voice from audio samples, enabling text-to-speech in any voice for applications like personalized assistants and content localization.

Why It Matters

Voice cloning enables personalized TTS at scale. Content creators can narrate in their own voice without recording every word. Businesses can create consistent brand voices. The technology enables dubbing videos into other languages while preserving the original speaker’s voice.

How It Works

  1. Sample Collection: Record 10 seconds to several minutes of target voice
  2. Voice Encoding: Extract voice characteristics (timbre, pitch, accent)
  3. Model Training/Adaptation: Train or fine-tune TTS to replicate voice
  4. Generation: Synthesize new speech in the cloned voice
