Hearing a sound is only half the battle. To truly master pronunciation, you need to know how to move your lips, jaw, and tongue. Sound By Sound Slowly solves this by generating hyper-realistic visual guides.

Using open-source Facefusion deepfake technology, our platform maps precise phonetic lip movements onto digital avatars. This creates seamless, high-framerate GIFs that visually break down exactly how your mouth should look while speaking the phrase you are learning.

Why it changes the game

  • Visual Imitation: Mimicking native speakers is proven to be one of the fastest ways to eliminate accents.
  • Nuanced Details: See the subtle differences between similar sounds, like the French "u" vs "ou", or the English "v" vs "w".
  • Custom Generated: The visual guides are generated on-the-fly for any word or phrase you type into the app.
