The OnePlus TV is rumoured to feature Alexa voice control according to Amazon India's Alexa skill page.
The Android TV is Bluetooth certified and OnePlus CEO and founder Pete Lau has been very vocal in saying that connectivity will be a big feature, and adding Alexa voice control is very much a part of that. Supported voice commands include power on/off, tweaking the volume, and changing the channel and input.
The fact that it's been certified for Alexa skills means that you'll be able to control the TV using other Alexa-enabled devices, as well as using the slinky remote control that Lau recently tweeted a picture of.
The TV is expected to make its debut at the end of the month, and will be launching in India first. [TechRadar]
