I'm really interested in learning Hebrew. But all the different websites I've found say different things. stressed So I don't really know what's correct and what's not.

Like, how do you know when to use ת and when to use ט?


That not in how you say it, its in the meaning of the word. Most words have a three letter root, and the root tells you the basic meaning.
There's no rule at all. Those two letters used to stand for different sounds. Today they've merged into one. The way it is written reflects the way it used to be said, and the only way to know is memorizing it. Even kids who grew up speaking Hebrew just have to memorize that when they learn to read and write.


Same story with כ and ח, or כּ and ק, or ע, א and often even ה. They're all usually pronounced as a glottal stop (ʔ). In case of ה sometimes it's heard, often it really doesn't matter.

I think probably about half of Israelis don't speak Hebrew as their first language. Modern Hebrew is very tolerant of foreign accents, and variations in pronunciation often don't change the meaning of the word.
