On screen keyboard dictation issue

iOS and iPadOS

Hi all, I've been having dictation issues lately. When I use the on screen keyboard to dictate either a text message or anything else, dictation is horrible. I say a whole sentence and dictation either doesn't input anything that I said or puts in something totally different than what I said. Anyone know how to fix this? Thanks. I'm using an iPhone XR with the latest software build. Also, when I do an audio message or facebook live video, my voice sounds realy staticky.
