Google Chrome users may be interested in this review from Extreme Tech about Google “Voice Typing.” According to the review:
Voice Typing is different, though; it’s kind of a built-in version of Dragon NaturallySpeaking (for those of you who remember and/or still use that program). Voice Typing works in Chrome on the desktop, as well as the Docs apps for Apple iOS (iPhone and iPad) and Android.
Voice Typing does have some shortcomings and probably won’t replace a full-fledged dictation program like Dragon Naturally Speaking, but it is free, has potential and is certainly worth experimenting with if you are a Chrome user.
