Throat vibration
Voiced or voiceless — the difference between ग and क. Put a hand on your throat; the app tells you whether the buzz was there.
Visual pronunciation practice
Feel the sound. See the feedback.
Sign & Talk listens to your raw voice — no noise filter, no autocorrect — and turns every sound into something you can feel and see: throat buzz, air puff, tongue position. Built first for deaf and hard-of-hearing learners.

Phoneme-level analysisNothing audio-onlyYour pace, no streak shaming
Why normal speech apps fail here
Other apps clean up your voice. We keep it honest.
Noise suppression and language models quietly “fix” unclear speech into the nearest valid word. That is exactly wrong for a learner who cannot hear the difference. Sign & Talk measures the sound you actually made and explains it physically.
Air puff
Aspiration — the extra breath that turns क into ख. Hold a palm in front of your lips and match what the app measured.
Tongue & lips
Where the sound is made: lips, teeth, ridge, palate, back. A diagram you can copy in a mirror, not a score you have to guess from.
Feedback that meets you where you are
A score, and the reason behind it.
Every attempt comes back as a phoneme-by-phoneme comparison, a confidence per sound and a plain-language next step. Nothing important is audio-only.
- ✓ Heard vs. target, sound by sound — substitutions, missing, extra
- ✓ A graded 0–100 confidence for each sound, not pass/fail
- ✓ Acoustic measurements: voice onset, pitch, aspiration, vowel shape
- ✓ Unusable recordings are returned for a free retry
Built for the real learning journey
From a single sound to self-expression.
Start with sounds
Sounds grouped by how they are made — स्वर, क-वर्ग, च-वर्ग… — each with a mouth diagram and a physical hint you can check with your own hands.
Grow into words
Type any Devanagari word. It is broken into phonemes and each one is checked in context — beginning, middle, end.
Speak whole thoughts
Sentences add rhythm and stress. Your history shows which sounds are reliable and which deserve another look.
