If you wanted your Mac to serve as a dictation machine up till now, you needed a third-party app, such as Nuance’s Dragon Dictate, along with a specialized headset or mic. Mountain Lion makes it simple with Dictate, Apple’s cloud-based solution for voice typing. This feature works in almost any app that has a text entry feature and also uses your Mac’s Contact app to spell the names of your contacts correctly.
Fortunately, Dictate is very simple to set up and use. You don’t need to spend extended amounts of time speaking silly paragraphs to train your Mac.
Dictate defaults to your Mac’s Internal microphone, but you can click the tiny arrow to produce a drop-down menu where you can select a different mic.
You can also click the Shortcut menu to choose a different set of keystrokes for enabling Dictation.
This Mountain Lion feature can have trouble with names and using all caps can be dicey, but Dictate is otherwise pretty accurate. We wished that it did more with formatting but the accuracy is very impressive. This article is an example.
