By the way, Yemenis pronounce the hard ג wrong. Like Arabs.
ג is supposed to be from the palate, G (like the soft ג which they do get right, indeed, GH), not the teeth
And nobody pronounces the ר correctly, which should be a J and soft ר should be ZH.
The English RR is the best substitute, and the best pronunciation of ר that exists today, because at least it comes from teeth, like supposed to.
But, ya, should be J and ZH. They are 3 Reshs, you know that, right?
