The more you use Alexa, the more she adapts to your voice, vocabulary and personal preferences. When you enable hands free with Alexa, you can talk to Alexa by simply saying “Alexa” when the app is on your screen. Use the Amazon Alexa app to manage Alexa-enabled devices, control music playback, view shopping lists on the go, keep track of upcoming reminders, check on active timers and much more.
