My "lazy" English

I had my acting class last night. I will not blog too much about it, promise. Well, anyway I had it and it was, as usual, great. It will be very centered around voice work, which I find a bit sad as I love the physicality of acting, but I do need to work on my voice and well, my accent. I blogged about my accent before. I read a poem twice, the first time was so-so, the second time was great. But I do sound foreign. My teacher said that I had a very good but "lazy" English. It was a back handed compliment, I think. She asked if I spoke French at home (I very rarely do). Anyway, I need to eliminate some parts of my accent, at least for the stage (or, in that case, for recording): the "th" which I pronounce "d" like all Quebeckers, for instance. I could get away with it before as I was playing a Russian character, but this time I will have to play a native English speaker (wish I could play an alienated guy from Chicoutimi). So I need to get something more akin to an English accent, which I never managed to get in more than ten years here. My teacher said that I can easily correct my diction in two months. Interesting challenge, getting rid of my lazy English.
