>I listen to books on tape a lot and love the HP books as well. Book one is 8:17 long, 2 is 9:18, 3 is 11:51, and book 4 is 20:52. So not only is each one longer. They appear to grow exponentially. To lazy to calculate the trend, but it's a biggie.

I am getting so good at reading these books outloud, I wonder if I could do it professionally. I no longer get caught in a monotone voice, but I also do not change my voice depending on who is speaking. Are the HP books read aloud by American English speakers or British English speakers?
