Oh absolutely. The amount of times I have to pause, take a deep breathe and OVER-enunciate (still with mixed success) because my voice, pulse rise and my patience decreases with every absolute butchering (like not even "close but no cigar" but "how on earth did you come up with that?") Siri does to dictated text message in CarPlay...

I don’t even bother anymore. When it reads back the text message and asks if I want to send it I just laugh heartily and say yeah. Sometimes the recipient has to read it aloud and try to phonetically guess what the original words were.
