What is a good comeback to a man making fun of your voice?

I’ve worked in male dominated spaces my entire career and something that bothers me so much is when men jokingly mimic a woman’s high pitched voice to express their unhappiness with a situation or conversation. I was just watching a TV show where a man in power did this towards a woman in power who won a deal over him. She just laughed it off, but i hate the idea of just laughing off such a petty and cry baby move. Usually it’s done is a pretty light hearted manner, but it’s still so sexist and I haven’t found a good way to respond that isn’t ultra serious and gets turned back on me. I don’t mind telling men when they are acting in appropriately, but usually in this situation, it’s a playful mimicking that I still think is an easy, sexist cop out. Any ideas?
