Google Home is set to battle Amazon's Echo for voice control of the smart home

OK Google, it's time to take aim at Alexa. Google has announced that consumers can now preorder its Google Home digital assistant for 129, with a ship date of November 4. First revealed at Google I/O in May, Google Home will compete with Amazon's surprisingly popular Echo product line for voice-activated control of the smart home. The price tag is attractive, and it has some features the Echo doesn't, but Google still has a lot of work to do to catch Amazon. Like the Echo, Google Home can recognize natural language and answer simple questions when it detects a "wake" word ("OK Google" for the Google Home, "Alexa" for the Echo). Google has a leg up on Amazon in this regard, as it arguably has the world's best search engine, and the company has been working on speech recognition for many years longer than Amazon.
