I love that assistance. I'm giving you a freaking lingot because you made a recording!
However, I'm told the "J" is intended to be closer to the J in "judge" or the z in azure (so more like a French J, right?). It's the vowel transition I struggle with...
The ‹j› is originally (and classically) a semivowel [j], like the English 'y' in 'yes'. However, it was [ɟ] – similar but not quite the same as in "judge" – when before /i/ and sometimes before /e/.
"Modern" (non-native) HV speakers vary between the yes-sound, the judge-sound, and the azure-sound, depending on their source languages. For more details see here: https://wiki.dothraki.org/High_Valyrian_Phonology
FYI for this course, we're doing the Daenerys pronunciations of and , not the original pronunciations.
I'm not quite sure what you mean, but nouns don't agree with other nouns. Vale is "man" in the accusative, and it has that form because it's the object of the sentence. It doesn't have to agree with the subject.
