“oo” as in book

Written /ʊ/ in the phonetic alphabet — but you will never need that in the app.

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.

What tends to come out instead

“oo” slipping into “oo” (as in moon)

Relax your lip rounding, keep the vowel short, and let the tongue sit slightly lower and more central.

“Too much kiss, too much time! This vowel is short and casual — relax the lips, quick like a nod. Uh-huh!”Nunzio, when he hears it

Where it lives in real words

put full good looks would should

In the app, this sound is put under pressure in Everyday English — whole sentences built so it cannot hide.

Compared head to head

The classic mix-ups involving this sound, one page per pair: book vs moon.

It also likes to turn up uninvited

People often say “oo” when a word actually wants “oo” as in moon — each of those pages shows the way back.

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.
