Voice Cloning
Creating a synthetic voice that sounds like a specific person from a few audio samples—read text in your voice.
Think of it like
Recording yourself saying different phonemes then auto-combining them to say anything.
Example
30 seconds of your voice; AI generates "I will call you later" in your accent, tone, and speaking style.
How it actually works
Speaker encoder learns embeddings from reference audio (speaker verification). TTS conditioned on speaker embedding. Training requires 1-10 hours of target speaker data for good quality; few-shot with 10 seconds possible but lower quality. Can be misused for deepfakes; watermarking and detection critical.
For product teams
Personalization and accessibility; also raises consent and fraud concerns.
For engineers
Speaker encoder extracts speaker embedding from reference; TTS conditioned on embedding; attention learns target speaker prosody.
