Freaks me out

Last week I wrote and recorded the listening test for the first year students at Tokamachi. The students are taking this test right now. The test has to be done simultaneously across all nine forst year classes, so the school are broadcasting the test over the school's PA system. I may be in a completely different part of the school, but with all the windows open because of the heat, I can hear myself telling students about watching soccer after school. It's quite embarassing. Did I really write that passage? Could I speak any slower? Do I really sound like that on tape?
