Amazon wants to make its virtual assistant Alexa available on more devices, instead of just its own hardware. To that end, the company today is broadly opening up access to developer tools that will allow commercial device makers to build products powered by Alexa. With the launch of the Alexa Voice Service Device SDK, as the toolset is called, companies can add a fully functional version of Alexa to their devices that’s able to handle speech recognition, as well as other Alexa functionality, like streaming media, using timers and alarms, notifications, weather reports, and accessing the thousands of voice apps, known as Alexa skills.

The SDK was previously available in an invite-only developer preview period, says Amazon. During this period, over 50 commercial device makers have been working to add Alexa to their products.
