5 things you didn't know about Amazon's 'Alexa'

Amazon's Echo voice-activated speaker has more "skills" than you may be using. Amazon's Echo has become a sleeper hit thanks to tasks its digital assistant Alexa can carry out. There's probably more you could do with it. In case you haven't played around with an Echo or similar Alexa-driven voice speakers, the 179 cylindrical-shaped, cloud-connected speaker sits in a room and you use your voice to ask a question or give a command. Using the wake word "Alexa," a sensitive microphone picks up the request and dishes up the info you want in a human-like voice.
