Who I have the same questioned this topic

I have a Galaxy Note 8 and Verizon. The voice-to-text used to be just wonderful, hardly ever missing a word, and when it did the suggestions were usually right on target. Now, it's suddenly capitalizing words in the middle of a sentence, if you hesitate just one second after a word it will automatically put a period in. If the words are really wrong the suggestions are so off base. It used to take a look at the entire sentence and figure out what the right word was. No more. Any thoughts as to what I might do? Thanks in advance for your help.
