I think we need some clarification over "א". Aleph is a silent letter, and the only reason why it makes vowel sounds in most words is because in the niqqud writing system, there is a niqqud written with the aleph that gives it its sound. For example, "אהבא" is love in Standard Hebrew, in the ktiv male writing system. Ktiv male basically just omits the niqqud symbols, and it's the system used to write normally in Hebrew today. However, love can also be written this way: "אָהָבַה". The first aleph takes the vowel sound of the kamatz written under it, as does the second hei with its kamatz, and the bet with its patach. In the Hebrew word for "or", "או", the aleph is silent, but the vav takes the vowel sound of "oe", which is why "או" is pronounced "oe", like in Spanish.
Just a slight addition, או is not pronounced /oe/. LazyFailure just wrote "oe" to clarify that it was pronounced /o/, with a long o like in Spanish. Also, while I'm here, אהבה (can't type niqqud) would be pronounced /a.haˈva/ (ah-ha-VAH) for anyone wondering. It really would be worth it to take a bit of time to learn niqqud, since it's used a lot for beginners and in dictionaries. [2019/03/25]
"oh" would be vowel pointed with a dot over the va.
"oo" would be vowel pointed with the dot in the va - underneath the diagonal line that we are not seeing, or to the left of the line.
Personally, I detest this Hebrew font because vav, yud and final-chaf look alike on the keyboard when trying to figure out which one is vav. And, a traditional Hebraic vav or yud look nothing like we see in this font. Modernist and their silly overly simplistic fonts drive me nuts! And, Israel allowed this font to be acceptable. :P
Also, seeing the vowel pointing would be very useful so that we can know how it would be pronounced here - especially when you have auditory processing issues or are deaf. Even in Israel, beginner learners get the vowel pointing. However, I do understand the amount of letters that would have to be given for us to click on in order to get the one with the right vowel point. And I do understand that Adults do not get the vowel pointing.

Copy the letters into word pad (or words like I do so far) and paste. That way you are doing the translating.

Look at "א" as a resting place for vowels. Most of the time, "א" has an "a/ah" sound. Next most often it has an "eh" sound. Sometimes, it will have an "o/oh" sound. Usually if it has an "o/oh" or "u/oo" sound, as in "boot", a "vav" will follow the "alef, "או". To make an "i/ee" or "e/ai" sound, a "yod" will follow the "alef", "אי". When "nikkud", the dots, are used, they tell you exactly which vowel sound is made. Otherwise, you just have to memorize how the words sound.
