OS X includes a nifty Dictation feature which allows you to control your Mac and apps with your voice. You can use “speakable items”, basically a set of spoken commands, to open apps, choose menu items, email contacts and convert whole spoken sentences to text, wherever you can type text.
This is much like iOS’s Dictation feature as both iOS and OS X use the same Nuance-powered technology that turns speech to text. iOS devices have limited computing power so the Dictation feature on the iPhone, iPod touch and iPad requires network connectivity in iOS 7 (iOS 8 supports streaming voice recognition and 22 new languages).
On the Mac, computing resources like CPU power, battery life and RAM are not of paramount importance as on mobile, Therefore, OS X Mavericks provides a new Enhanced Dictation feature which converts your words to text without utilizing Apple’s servers.
In other words, server-based Dictation lets you dictate without an active Internet connection. Because voice recognition processing runs locally on your Mac, text appears instantly as you speak. That is: continuos, streaming dictation with live feedback is made possible.
In this tutorial, I’m going to show you how to turn on Enhanced Dictation in OS X and take advantage of speech-to-text, even when you're off the grid...
