I checked in google translate but I wanted to be sure. Is 思う pronounced as "omou" or "omoo"? Usually when there is a お (or こ、ど etc), followed by a う, the う is pronounced as お, but I was not sure if that was the case with verbs as well.
It is "omou" not "omoo" at least I've actually heard it pronounced this way.
- In 1 word "oo" or "ou" both are long "o".
- In two words put together, you have to know how they are pronounced seperatly and it doesn't really change. If you have a verb ending in ou then the final u will be "u" not "o".
When I have doubts about the pronunciation of a word I rather use this site because Google is not too reliable ...
