The 15 Most Useful iPhone and Android Voice Commands

I'll be honest: Even though I'm supposed to be a technology expert, I've long resisted using Siri and my smartphone's voice commands. All the errors were frustrating and often seemed to eat up more time than just typing in commands and opening up apps manually. These days, though, I've found myself using Siri more often. Speech recognition has gotten a lot better, and Siri has gotten a lot smarter and more powerful. You can do virtually anything via your phone's voice commands, from posting to Twitter to finding the best pizza pie to figuring out just how deep 20,000 leagues really is.
