Hi JulieLuhring,
Thanks for your post in Microsoft Community.
I'm Mosken, I do apologize for the inconvenience that you're experiencing right now, let me help you sort things out.
According to your description, I knew that your speech-to-text function cannot be opened with "win" + "H", but other function shortcut keys are normal. If my understanding is wrong, please correct me in the reply.
Then I suggest that you can try to find the crux of the problem by doing the following:
1.You can open this function not only through the shortcut key, but also through the "Win" logo key + "Q", enter "speech", and select "Windows Speech Recognition" (You can also pin it to the taskbar or start menu) to open it.
2.Maybe you didn't turn on this function after updating the system, you can turn it on by "Ctrl" + "Win" + "S" shortcut, or "Win" logo key + "Q", enter "dictation", select "Ease of Access dictation", open "Speech" settings, then open "Turn on Speech Recognition", then you can try to use "win" + "H" to open the function.
3.Make sure the audio input device is connected properly and the system has access to the microphone ("win" logo key + "I" to open "Settings" > "Privacy" > "Windows permissions" > "speech", turn it on).
I wish the above will be helpful to you. Please feel free to let me know how it goes, and I will do my best to help you.
