I'm having lots of problems with the voice to text

I’m having lots of problems with the voice to text. I use Windows key H and it brings up a prompt that listens to my voice. But when I go back to check it’s leaving words out partially spelling words and a lot of other things so it’s very inconvenient Dictate paragraphs and then have to go back and check it again. I have a microphone Mouth is very close to it so I don’t know what other kind of problems that it could be so if someone please help that would be helpful

sorry I just found out this is a Windows speach to text.
