Whispp


When stuttering people whisper, they stutter up to 85% less. That's why we develop Whispp: the app that converts whispers into your own natural voice without delay.

Calling whispered

Whispp makes it possible

Without lag, the conversation partner on the other side of the line hears the normal voice. This enables a relaxed conversation. Without stuttering.
