Unfortunately, I don't know French, so that's a bit like telling me that the French 'r' sounds like the Hebrew 'r'. However, saying that it might sound like an 'l' when listening over speakers makes sense. Thanks. :)
Now that I've been listening to it for a while, I'd say that the Hebrew 'r' is pronounced at the back of the jaw / mouth. Cheers. :)
There are a bunch of terms for it, but you use your uvula, so one term is "uvular", and another is "guttural". And you're right: the sound is made in the back of the mouth.
I don't know French either, but I've heard enough fake French and French accents to know what the "r" sounds like!
