Dictation problems

I have a new iMac and because I am a lousy speller I rely on Apples dictation within my new iMac. The problem I am experiencing and need help with is, capitalization in the middle of a sentence when a capitalization is not necessary. It will capitalize words like, will, through, can, and others. 


When I first purchased my PC about two months ago I was running Sierra and I just upgraded to high Sierra. The problem I mentioned exists in both operating systems.

Please let me know if anyone has any fixes?


Yesterday I posted the same question and received two replies by email but I am having a dead end time logging in to the community to read it. Please excuse me for reposting twice.
