Making Google voice typing work for me on iOS?

I have been using Google voice typing on the PC Google docs for the past week or so. I have found it to be very accurate even rivalling the dictation quality I have received using Dragon Naturally Speaking. Google voice typing is not available within the iOS Google docs app unfortunately. I'm aware that you can use Google voice typing if you install Google keyboard unfortunately I have found this to be inaccessible. I am writing task if anyone is aware of a way I can use a Google voice typing on iOS in a way that is accessible with voiceover.
