Seamless voice and video communication

Whispp’s app’s heart is its ability to enable seamless voice and video communication through real-time audio-to-audio AI conversion. By converting whispered speech and affected speech into clear, natural voice during phone and video calls and through voice and video messages, Whispp enables people with voice problems to communicate in various situations confidently.

Soon, live conversation mode will further enhance Whispp’s impact by enabling real-time, face-to-face interactions – a game-changer for spontaneous and face-to-face communication. This feature builds on Whispp’s ability to transform whispers or soft speech into clear, natural speech, enabling effortless communication in everyday conversations.

TIME’s Best Inventions

Each year, Time Magazine compiles the list of TIME’s Best Inventions. The innovations improve the way we deliver. Many successful companies preceded Whispp. Some notable winners from 2023 include the Owala FreeSip water bottle with a unique system for both sipping and drinking, the weight loss drug Wegovy, the Alzheimer’s drug Leqembi, and the recently approved RSV vaccine, Arexvy. These innovations were praised for their ease of use, contribution to improving health, and practicality in everyday life.

The Whisp App

Whispp differs fundamentally from existing speech conversion technologies because it uses voiceless speech (with no discernible pitch) into a natural and clear voice. To do so, the company uses audio-to-audio-based AI, resulting in real-time speech conversion, which is highly scalable due to its language-independent nature. Each user can re-create their voice by providing recordings of their current or former healthy voice, giving a personalized twist to communication. People who stutter severely can reduce their stutter frequency by an average of 85% when they whisper. In addition, people suffering from spasmodic dysphonia or recurrent respiratory papillomatosis speak much more relaxed and fluent when they whisper.
