When it comes to gadgets, Amazon is best known for its line of Echo smart speakers, Kindle e-readers, and Fire TVs and tablets. But based on reports, it sounds like the online retail giant has a lot more in its pipeline. Amazon is reportedly planning to bring its popular Alexa assistant to a slew of new gadgets including home robots and earbuds. Such a move would give Amazon a way to expand its voice-enabled helper beyond the home, a market in which the company’s Echo devices have already maintained a steady lead over rivals like Google. Amazon is developing a new Echo that could be released by next year, according to Bloomberg. That wouldn’t be too surprising considering Amazon has previously released new Echo products in the fall. The report doesn’t say much about the new Echo, other than that it’s shaped like a cylinder just like the company’s current speaker and that it’s wider than the version Amazon sells today. That extra space is being used to fit additional components in the device, the report says.
