One of the 40 sounds Nunzio listens for. When you read a sentence aloud, the app scores every single sound in it on your phone — this page is what he knows about this one: what tends to come out in its place, and what to do about it.
In the app, this sound is put under pressure in Everyday English — whole sentences built so it cannot hide.
Reading about a sound is one thing. Hearing which ones you miss is another.
Nunzio records you reading a sentence, scores every sound in it on your phone — nothing is uploaded — and tells you the one thing worth fixing. Nunzio — Accent Coach is coming to the App Store and Google Play.
