This is the audio for the list of examples in my Medium article article on this topic.

The vowel pair “OU” is actually unpredictable. Here are the 8 different ways that it can be pronounced.

• Long-O (as in “no”): dough / though / although / thorough / shoulder / soul / source / course / four / pour / your / court / gourd / mourn
• Short-o (as in “not”): thought / bought / cough / fought / ought / brought
• Long-U (as in “true”): soup / through / routine / group / detour / youth / you
• Short-u (as in “fun”): country / couple / cousin / enough / rough / southern / tough / trouble / touch / young
• Short-oo (as in “good”): could / couldn’t / would / wouldn’t / should / shouldn’t
• Vowel /aw/: about / amount / cloud / couch / count / county / doubt / found / ground / hour / house / loud / mouse / mountain / mouth / noun / our / out / ounce / pound / proud / round / shout / sound / south / spout / thousand / trout
• Schwa /ə/ for the suffix “-OUS”: enormous / nervous / famous / cautious / obvious / various / serious / tedious
• R-vowel: adjourn / courage / courier / encourage / journal / journey / scourge / your

And just to keep it interesting, there is a word with two pronunciations! The word “route” can be said with Vowel /aw/ or Long-U.
