How do I turn off Voice Over Text punctuation in latest ios update?

Thank you @Bailier, but at this point it's best to just turn off Auto-Punctuation.

If you contact Apple Support they run you though about 30 mins of settings and testing things that don't make a difference, then give you a link and tell you how you can submit feedback about the problem. But to be perfectly honest, 99.9% of the time feedback isn't read because Apple gets so much spam. So legitimate issues like this aren't going to be noticed in a timely manner when submitting through the feedback form. We simply have to wait for the engineers to decide this is a problem which may not happen until the next major iOS update.

I mention this not as an attack on Apple, but simply because if you have reached this post then you have already become extremely frustrated with the amount of time you've had to waste correcting the punctuation. And I don't want other users experiencing this problem to waste 30-45 minutes more of their time with an Apple support rep when speaking with one won't solve this specific problem. The reality is that there are lots of issues like these that the support reps aren't trained on, and that don't get acknowledged by Apple nor fixed until the engineers themselves become exasperated by the issue.

In the meantime, the best solution is to simply turn it off entirely as outlined in the prior message.

Unfortunately it's been 4 months and iphone updates haven't yet fixed the problem of dictation adding punctuation all over the place without rhyme or reason.

For those of you still experiencing it, you can simply turn off auto-punctuation by doing the following:

Settings>General>Keyboard>Dictation>Auto-Punctuation
