You'll need to speak punctuation. It's also better over long dictation but do try and keep it under 1 paragraph at a time. Most of the time it will also take out any ahs, uhms, and ohs when you're speaking.
So you'll have to say "I like to eat bacon (comma) eggs (comma) and toast for breakfast (period)"?
How does it know you don't want the words comma and period in your sentences?
What if you make a mistake? Can you delete a sentence/word through the voice capabilities?
It's been designed this way since voice dictation was released back in the early 90s I think. I'm still upset there's no "Magic Word" since I'm too lazy to push the damn button.
