Written by two veterans of the Apple world, “Talking to Siri: Learning the Language of Apple’s Intelligent Assistant” is a short, US$4.99 ebook that teaches readers how to use Siri.

Siri, introduced with the iPhone 4S, lets you use your voice to send messages, schedule meetings, place phone calls, and more. Apple says that you can ask Siri to do things just by talking the way you talk. I haven’t tried it, but Apple says Siri understands what you say, knows what you mean, and even talks back. What differentiates Siri from competing technologies is its ability to not only recognize words spoken in a normal tone of voice, but its capacity to pick up on the contextual meaning of a phrase, according to Apple.

“Talking to Siri” offers practical, how-to advice mixed with examples. Tutorials show you how to set up Siri in your preferences, and how to manage the interactive conversations you have with your voice assistant.

Talking to Siri was written by two veterans of the Apple world, Erica Sadun and Steve Sande. Both are writers at AOL Tech’s “The Unofficial Apple Weblog (TUAW).” For more info go to http://www.sanddunetech.com .
