Talk to Text with newest Apple Updates

Is there a way to get Apple to fix the grammar/punctuation with talk to text? I teach high school and middle school English, and with the latest Apple update, talk to text adds commas in random places whenever I pause while speaking. As a teacher, it is hard enough to teach students where to use commas, periods, semicolons, and other forms of punctuation, let alone if the device they rely on demonstrates incorrect punctuation. I’ve also worked in corporate America, and this is not an isolated problem for children. I’m spending more time fixing the punctuation when I use talk to text then I am writing the message from hand. Apple needs to do better or take the feature down.
