You already know English. Now make it sound right. In a job interview, a client call, or a presentation, the gap between correct English and convincing English is how it sounds โ€” the rhythm, the stress, the melody of the sentence. ProperSound trains exactly that, the way interpreters and actors train: by mimicking a perfect model until it becomes your own voice. HOW IT WORKS 1. Listen to a sentence spoken the way it should sound. 2. Speak it back โ€” mimic the model's rhythm, stress, and melody. 3. Hear your voice and the model side by side, and see exactly where you differ. The difference is the lesson. No scores, no grades. Your own ears are the judge โ€” the way professionals have always trained their voice. HEAR YOUR OWN VOICE, PERFECTED ProperSound doesn't just compare โ€” it corrects. โ€ข Plug in wired headphones and your voice is tuned toward the model in real time as you speak. You hear yourself sounding right while you practice. โ€ข After every take, replay a perfected version rendered from your own recording โ€” your voice, with the model's polish. This is what you should sound like. โ€ข The model audio itself is enhanced so the cues learners usually miss โ€” sentence stress, crisp consonants, linking โ€” stand out clearly. SEE THE DIFFERENCE โ€ข Your waveform overlaid on the model's: rhythm and pauses at a glance. โ€ข A band-by-band sound profile shows exactly where your energy falls short of the model. โ€ข Every sentence comes with its stress pattern, IPA transcription, and a coaching tip written for that exact sentence. ENGLISH FOR REAL SITUATIONS Practice the sentences professionals actually say: โ€ข Job interviews โ€” introduce yourself, answer with the STAR method โ€ข Workplace communication โ€” meetings, small talk, difficult conversations โ€ข Presentations โ€” open, transition, persuade, close โ€ข Financial news โ€” read the markets aloud like a broadcast anchor โ€ข Daily life, travel, and campus English From your first sounds to native-level delivery, with six US and UK studio voices to train your ear. WORKS ANYWHERE, STAYS PRIVATE Every lesson and every recording ships inside the app. Nothing to download, nothing to stream, no account needed to look around. Practice on a plane, on the subway, anywhere. Your voice never leaves your device: recordings and progress are stored locally and are never uploaded to us or anyone else.
