hi, yeah. i understand that. i think the inflection on the m20 is meaning inflections at question marks, exclamation points, etc. you can't actually change the inflection, that is, the differences in pitch, we can't change the inflection, and i thought it'd be nice to have it, so people can set how monotone they want their bp. as for articulation, it's how clearly sounds come out, like on 0 articulation, it might sound something like ardigulation and on 9, it's quite a lot clearer, maybe that was something that people noticed. i'd like to be able to change that, as i have trouble understanding things if they're not reasonably clear, and it's just another good option to have for a more customizable voice. brandon
