Google's voice commands are excellent at making texting easier. Recently, Google made this even better, adding an answering machine-style command that allows you to read your last five messages.
To activate this feature, simply say "show me my last messages" and Google will start reading your messages. For each message, Google will say who it's from, ask if you want to hear the message read aloud, or skip it. If you listen to the message, you're then asked if you'd like to reply, which you can do by speaking your message. This is pretty handy if you need to reply to a message while driving, or don't have your hands free.
