Privacy by design

Your text is sent to our server only to convert letters into pronunciation symbols (phonemes). This is instant and stateless — your text is never logged, stored, or used for anything else. The speech generation itself runs 100% in your browser via a neural network. For maximum privacy, the Utterly app handles everything on-device.
