“In OS X Mavericks, you now have the option of downloading a file that supports offline dictation,” David Sparks reports for Macworld. “To set it up, you go to the Dictation & Speech pane in System Preferences and tick the Use Enhanced Dictation box. That causes the file to download”
“Having this transcription-support file on your Mac dramatically improves the functionality of OS X’s built-in Dictation feature. Now, when you press the Fn key twice and start speaking, the words appear on screen as you speak,” Sparks reports. “But Mac dictation isn’t new to Mavericks. I’ve been dictating to computers for a long time. (When I first started dictating, you … had … to … talk … like … this … leaving … a … space … between … each … word.) My usual tool is Dragon Dictate for Mac. So when I heard that Apple was improving the Dictation tool in OS X, my first question was: How will it compare to Dragon?”
“The way I see it, Mavericks’s Dictation tool is like Dragon Dictate Lite,” Sparks reports. “The Mavericks tool’s best feature is the ability to activate it anywhere on my Mac and immediately start dictating; I’m using it in all sorts of unexpected places on my Mac. Dragon Dictate is not as easy to get working in any context, but when you need to dictate long passages of text, its increased accuracy makes it the clear choice.”
