MouthGym
Every sound, and what your mouth does
Tongue, lips, jaw, airflow, voicing — plus the mistakes people usually make with that sound.
/ˈmaʊθ.dʒɪm/ · pronunciation trainer
Train the sounds you actually get wrong.
Most people don't struggle with a language because they're short on words. They struggle because when they speak, they aren't understood. MouthGym fixes the physical part — one sound at a time.

How it works
One take. Three answers.
Say a word once and the app tells you how close you landed, which part slipped, and what to do with your mouth next time.
1
Listen
Hear a native model of the word, with its phonetic spelling and a sentence for context.
2
Say it back
Tap the mic and repeat it. Recognition runs on your phone, through Apple's speech engine.
3
See the fix
Get a score out of 100, read exactly what was heard, and see which syllable to correct.
Minimal pairs
Two words. One sound apart.
The fastest way to fix a sound is to hear it beside the sound you keep swapping it for. Train the ear first — the mouth follows.
ship
sip
/ʃ/ vs /s/
think
sink
/θ/ vs /s/
rice
lice
/ɹ/ vs /l/

bit
/iː/ vs /ɪ/
What's inside
A whole gym, not one machine.
Eight ways to practise, all drawing on the same library of words, sounds and native audio.
Tell the two apart, then say them apart
Contrast drills built per language, targeting the swaps that speakers of your language actually make.
Look up any word and hear it properly
Phonetic spelling, meaning, and a native reading — for anything you're about to have to say out loud.
Proof you're getting better
Streaks, accuracy over time, and the words you keep missing brought back by spaced repetition.
Languages
Seven to practise. Ten to read.
Each practice language ships with its own phoneme set, its own minimal pairs and its own native audio — not a translation of the English course.
