Microsoft's own Amazon Echo
Microsoft is preparing to launch a "HomeHub" feature in Windows 10 to control smart internet-connected devices, but rumors have also emerged of a separate "Home Hub" device with Cortana. Windows Central reports that Microsoft has an Amazon Echo competitor ready to unveil on October 26th, with Cortana built-in. The voice-activated speaker is said to include the ability to store files on the device, and respond to questions just like Alexa.
If Microsoft does reveal such a device then it will be up against strong competition from Amazon's Echo devices that have integrated hundreds of third-party apps and features. Google has also unveiled its Home device, and Apple is rumored to be working on its own Siri-powered hardware. Microsoft's own Cortana-powered device will have to do more than just answer questions.
