Alexa is an intelligent personal assistant developed by Amazon, made popular by the Amazon Echo and the Amazon Echo Dot devices developed by Amazon Lab126. It is capable of voice interaction, music playback, making to-do lists, setting alarms, streaming podcasts, playing audiobooks, and providing weather, traffic, and other real time information, such as news. Alexa can also control several smart devices using itself as a home automation system.
Most devices with Alexa allow users to activate the device using a wake-word (such as Echo); other devices (such as the Amazon app on iOS or Android) require the user to push a button to activate Alexa’s listening mode. Currently, interaction and communication with Alexa is only available in English and German.
