I did a great deal of searching of the topic and got no answer. Anyway, is the Argonian male voice broken because in my little research for voicing, all the races have individual voicing, with the humans and elves having a small variety, and orcs, khajiit, and even the female argonian having a unique voice. It's hinting to be a bug, but it's quite possible the voice was just never recorded.
Edit: PC refers to Player Character
