Siri name pronunciation bug

If I use the feature that Siri has where I tell her “that’s not how you pronounce that” and she asks how to pronounce and then she automatically starts listening but then stops listening almost instantly and then says “sorry I’m having trouble hearing you, can you try it again” and then she listens and stops listening almost instantly again. It only glitches out when I’m trying to teach her how to pronounce a name and I haven’t had it happen with any other commands
