Amazon Alexa: With a head start in the smart-home arena, Amazon’s Alexa boasts the widest range of compatible products. You can ask it anything, though its answers aren't always as accurate as Google's. Alexa supports a wide choice of Skills (like smartphone apps) that have been developed by third parties, and its speakers and smart displays are the most affordable, especially if you wait for big sale events like Prime Day. If you want to control Alexa from your phone, you need to install the Alexa app, and it must be open before you can issue a voice command.
