Command your Mac
Use Automator in Yosemite to automate tasks triggered with voice activation
In OS X Yosemite, Apple has revamped how you can speak to your Mac. Now going under the new name of Dictation Commands (previously Speakable Items), it enables you to specify, using typed words, the command you want to say in order to run a workflow that turns a manual task into one where your Mac does the work for you.
The simplest way to set up a command is in Accessibility under System Preferences. Under Dictation there, ‘Enable advanced commands’ lets you create new commands. Clicking the ‘+’ button reveals a form in which you can specify the words you want to say, limit your command’s availability to a single application, and define the Mac’s response – to open a file or an app, paste text or other data, run an existing workflow created in Automator or Script Editor, or mimic a keyboard shortcut being pressed.

Dictation Commands provide a way to deal with distracting tasks without leaving your current app.
