I make up voices how I imagine them.
Miss Bint to me speaks in a classic academic english accent, not some London slang or anything.
Phlexor speaks slowly with a humming voice which gives a slightly dim impression.
Schleed has a dramatic, sometimes girly and very intense voice which goes up in high pitched falsetto at times, and his irish accent is very evident. When he wants to make a point, he imitates scottish rolling "R" and goes up into falsetto.
Chris Gopher (gopher because of typical englishmen's resemblance to redskinned squirrels, beavers and hamsters) has a monotone, arrogant and lecturing voice, speaks quite fast but also silently without raising his voice, as if he doesn't breathe. He also makes these small squashy sounds with his lips and has a little too much saliva in the mouth which also makes small splashy sounds when he licks his, extremely thin, english lips which he does frequently.
Tigergirl has a nasal and screechy voice, like Fran Fine. She screams and yells more than she speaks and in a dialogue with Phlexor he's a like a "hum hum hum hum" replying silently and almost submissively.
Callaway sounds like a wannabe psychologist, very mellow and calm and even when she's angry her voice stays somewhat silky calm. Like Moiraine from Robert Jordan's Wheel of Time.
Benjimanbreeg has a very poorly articulated, slangy accent, similar to suburb accents in Swansea where "but" is pronounced "buh" and "water" is "waddaahh", "better" is "beddaaah" etc. He also has a typical mangiggle sounding a bit like "hohohoho" and laughs as if everything was an extremely dirty joke.
You seem to be lost in your own thoughts.
