For example:
* Spanish: "Ochu" could be a misspelling of "Ocho" (pronounced "oh-cho") meaning "eight".
* Japanese: "Ochu" could be a misspelling of "Otsu" (pronounced "oh-tsu") which is a city in Japan.
* Other languages: "Ochu" could be a word from another language entirely.
To help me understand, please tell me:
* What language are you interested in?
* What is the context of the word "Ochu"?
Once I have this information, I can give you a more accurate pronunciation.
