Play a song, look up contact information, open apps, check the weather, and more - all with your voice. Sound familiar?
On your iPhone, Apples Siri allows you to access a wide variety of information and perform different tasks. Now you can do most of the same on your Mac, even if it cannot run macOS Sierra or later. Quiri lets you use your voice to enter a command. It can tell you information about someone in your contacts list, schedule appointments, play songs and videos through iTunes, and open apps. Best of all, it works with OS X 10.11 (El Capitan).
Quiri will provide voice feedback to tell you about the results it came up with. It can also do more than just display text results - ask "What is [name]s birthday?" and Quiri will read it aloud and call up the relevant contact card. Tell Quiri to "Play [song name]" and iTunes will play the requested song. Say "Play [media name] on my Apple TV," and Quiri can even have iTunes stream the content to your Apple TV.
Quiri works best if you have installed the additional voice "Samantha," but this is not required. In the Dictation & Speech pane of System Preferences, select the "Text to Speech" tab, then under the "System Voice" drop-down menu, click on "Customize." Enable the voice from there.
