Is it normal i love how girls can change their voice depending on the situation

I like how they have a higher pitched voice for being cute, and when they feel more personal and intimate their voice gets a little deeper but softer, or when they're thinking really hard about something their voice is totally natural because they aren't putting much effort into making it sound different. Or when they are being sarcastic or teasing their voice reflects that. I like to listen to females speaking and try to pick out the emotions behind the voice and what's really going on in their heads.
