A listening notepad
This extension opens a box outside the browser and then you have to copy and paste the text. It also does not do any punctuation. But it is free. So far, the best option I have found to dictate on Windows and Google Chrome is an app called Lilly Speech which is available as a free version and also paid subscription of $30 a year. After trying the Speech recognition browser extensions, that is what I've been using so far.
It started writing "one hundred perc..." and then it switched to 100%! He he, I have no idea how this works but it works just fine.
works so well good punctation
