AITK for rejecting a girl in arranged marriage due to her voice?

Edit: Thank you for all your comments, everyone. While the majority of them are NTK, a few still fall under YTK. The NTK comments reason that since it's an arranged marriage, I have the right to make choices about such things. Meanwhile, the YTK ones criticize me for making this decision based solely on a phone call, which actually makes me an idiot rather than a kameena. So, the conclusion is: I am NTK, but YTI (yes, the idiot).

I have turned 28 and going for an arranged marriage route, my family is looking for potential brides for me. There was this rishta that came through a mutual family friend. Our bio-datas and pics were exchanged and both of us were fine with it. Taking things further, her family (along with her uncles) came to our house to meet my family and see me. They seemed happy and also said yes to me. Next, we were supposed to go to their place to see the girl and say yes if everything seemed ok. But before that, the girl and I somehow exchanged numbers and spoke on the phone. When I heard her voice for the first time, I was confused as to whom am I speaking with, as it was a male's voice. But I soon realized it was the girl only and her voice was masculine. We talked for about 15 minutes about stuff like hobbies and goals etc., the conversation went fine. But after the call, I just couldn't get the thing about her voice out of my head and decided I won't be able to work with this as intimacy is still a big factor if not everything. Therefore, I asked my parents to say no to them, but citing some made-up reason for not wanting to insult the girl.

But after this, I started feeling guilty for judging her on something that was given to her by god and having no control of her own at all. Also I am half-regretting at myself that I may have lost a potential good partner for such an issue, which I may have been able to work with. I also never had a romantic partner before, so don't know about that.

AITK for rejecting the girl just because of her voice?
