Unlike Siri for IoS and Google assistant, Alexa is an intelligent personal assistant developed by Amazon, first used in 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.
Alexa has thousands of skills with more added regularly. Skills add even more capabilities like ordering food from Zomato, requesting a ride from Ola, booking a carpenter from Urbanclap and more.
In the home automation space, Alexa can interact with devices from Belkin Wemo, ecobee, Geeni, IFTTT, Insteon, LIFX, LightwaveRF, Nest Thermostats, Philips Hue, SmartThings, Wink and Yonomi.
Alexa allows the user to hear updates on supported sports teams. A way to do this is by adding the sports team to the list created under Alexa’s Sports Update app section.
Messaging and calls
Amazon allows developers to build and publish skills for Alexa using the Alexa Skills Kit.
Amazon allows device manufacturers to integrate Alexa voice capabilities into their own connected products by using the Alexa Voice Service (AVS), a cloud-based service that provides APIs to interface with Alexa.
