Transgender reality TV star Caitlyn Jenner has admitted she worries her voice does't fit her new feminine appearance. The 65-year-old Olympian - who was previously known as Bruce Jenner before announcing her transition to female earlier this year - admitted watching her ESPYs speech on TV bothered her because she doesn't think her voice fits her new feminine appearance.Writing on her blog CaitlynJenner.com, she said: "While I felt like I looked great and that the gown looked fabulous, I still have a voice issue. It's not quite right compared to my feminine appearance. That bothers me a little bit. However, I hope that people don't listen to the pitch of my voice, but listen to what I have to say. That's important to me."Jenner was presented with the Arthur Ashe Courage Award this week and while she was nervous about giving a speech in front of a large crowd, she also worried about upsetting her children.She said: "The toughest part in the speech was my kids. It was hard to look over there and see all of my children. As I said in the speech, I don't want to hurt anybody. I just want to be myself. I barely got through that."..
