声音高。。一个错误吗？

Haiz…. Just realised that when your sound pitch too high people will think you are using fake voice … Then he commented that if can try not to use too much fake voice after the drama practise... Then he said don't cover the microphone as well.... Haih… and I know that my sound pitch kind of high that’s why I cover up the microphone so that its not that obvious… But another problem occurs.... He seems kinda annoyed with my voice...Then I realized another problem is… I don’t really know what to communicate with him…. Feel like he does not really like to talk with me… It is not a very big deal actually… BUT he will be one of my housemate soon… SO I guess our relationship should not be that awkward at least?
