A tumbkr account called Amagicrobor has been posting audio clips of all the My Room lines. Here's the link

For the ones I listened too, here's are my opinions.
Saizo: Decent, just as I imagined.
Kagero: A bit monotoned, but not horrible.
Izana: Can he say ANYTHING that won't kill me!?!?!?!?!?!? XD
Azura: A voice typical of a singer: I like it.
Siegbert: Not bad but something.....I can't put a finger on it.
Arthur: All I heard was justice :p. His voice suits hin VERY well.
Crimson: The debate is over, she's my Birthright waifu, the only one for me (and I'm literally the only one for her. :p)
Kazahana: She sounds quite energetic: again, she's like I imagined.
Shinonome Not what I expected: but its much better.
Xander: What might be his confession line is WAAY better than his Japanese one. His voice is fine.
Hisame: His voice is fine but......I'll explain below.
Hinata: Its fine, but not what I wwould use for him.
Ryoma: possibly biased, but one word: AMAZING! (Excpet the "kiss me you fool" line. What the heck?)
Kana: My daughter sounds so cute. :p.
Percy: What's up pitty patt?
However, I noticed that Treehouse gave Hisame the Henry/Gregor treatment. While he likes pickles in the japanese version, treehouse apparently has taken it up to eleven to the point of obbsession: Almosr ALL of Hisame's my roon lines have SOMETHING to do with pickles.
Also on a note, release is only hours away....
