The built-in Mavericks OS X speech recognition is a good piece of Voice recognition software to give you a taste of what speech recognition is like, but not as good as Dragon Dictate. This is mainly due to the complete lack of any correction capability. Here’s how it compares to Dragon Naturally Speaking, and how to enable the ‘Enhanced Dictation’ Mode which makes it a lot faster.
You may remember the launch of the first Macintosh in 1984. Steve Jobs said “today, for the first time ever, I’d like to let Macintosh speak for itself,” and the computer replies..
“Hello, I’m Macintosh. It sure is great to get out of that bag.”
Then in the 1990’s we had ‘Plaintalk’ and ‘Macintalk’. These were attempts to make the Macintosh computer human. There was also ‘Speakable Items’ where you could dictate short commands to the Mac.
In OSX 10.8 (Mountain Lion) Apple introduced “dictation.” It was basically an OS X version of ‘SIRI’ where your speech would be sent off to a server to be recognised and the text would come back to your computer.
In OS X 10.9 (Mavericks), for the first time, there is a usable speech recognition engine built-in to Mac OS X. There was not a lot of fanfare about it. In fact it almost comes as a hidden feature. You need to turn it on by enabling a mode called ‘Enhanced Dictation’ in the System Preferences. Despite this understated introduction, I think it’s one of the best things about OS X Mavericks.
The only thing lacking from the built in Mavericks dictation is correction. If correction arrives in the next version of OS X, it will be a game changer.
The one major flaw: No correction.
Mavericks Dictation would be to be very painful to use as a long term solution because there is no way of correcting mistakes and therefore helping it to learn. If there is a word it gets wrong, it will be getting it wrong forever. It works OK for me, but if it made any more mistakes that it did it would be un-usable without a correction and training feature.
One of the redeeming features of speech recognition software like Dragon Naturally Speaking (on the PC) and Dragon Dictate (on the Mac) is that even though it makes the occasional mistake, it has a correction feature. If you correct a word it will learn from this. The more mistakes you correct the better it gets.
There are lots of articles comparing the accuracy of Dragon dictate with the built in OS X dictation. But most of these articles fail to address this important difference. For example here at macworld they state that the accuracy of Dragon Dictate is 96.6 percent and for Mavericks’s Dictation is 89.6 percent. But no mention that the Mavericks has no learning ability. Here they compare the speed of dictation between the two programs. Again, they miss the biggest difference.
The biggest difference is not the accuracy or the speed. The biggest difference is the ability to learn. Accuracy and speed can both improve as the software learns to adapt to your voice. This means that Dragon Dictate will continue to improve as you use it. The OS X built-in dictation will continue to be stuck with words it doesn’t understand.
If you are thinking of speech recognition, the built in Maverick’s OS X speech recognition might be a good trial. If you like what you see, go and buy Dragon Dictate. If you don’t like it, stay away!
Enabling the “Enhanced Dictation”
By default the Dictation seems to be similar to SIRI based speech recognition. It sends your speech over the Internet to Apple to be recognised. But the OS X dictate has an option to download the speech files and then recognise your speech locally like Dragon does.
To enable this you need to go into the System Preferences. Under “Dictation” there is a checkbox called “use enhanced dictation.” If you check this box it will download the speech files that you need.

Unlike Dragon Dictate, there is no training involved. The built in, untrained speech recognition does a reasonably good job. Look at this:
Compare this with Dragon Dictate. Dragon Dictate is slightly better:
Here is an example of where the Mavericks OS X built-in dictation seems to be going a bit better:
If you are going to attempt to seriously use the built-in OS X dictation, I suggest you get yourself a good microphone. You really need a good headset microphone with some noise cancellation that is either Bluetooth or USB compatible. I suggest you check out knowbrainer.com. I got a great Samson wireless headset from them.
The built-in Mavericks OS X speech recognition is in my opinion a good trail. It is almost as accurate as Dragon Dictate and will give you a feel for speech recognition provided (1) you have a good microphone and (2) you are expecting it to be a trial, not a viable long term speech recognition product.
It sounds like Nuance’s Dragon engine is what powers SIRI. If that’s the case, if Apple add correction to their Dictation app then Nuance’s Dragon Dictate would become completely obsolete. It will be interesting to see what happens in the future with Apple’s Dictation.
My suggestion is to try out OSX Dictation (in Enhanced Mode), and if you like it, go and buy Dragon Dictate.
