How does it work?

Sounding Board is built on top of the Alexa Skills Kit powered by Echo devices, and most of the computation is done in the cloud.

At each talk turn, the Echo device sends the recognized text to our cloud system. There, our algorithm decides how to take the conversation further through a two-tiered dialogue manager. Based on what the user said, we may query our databases for recent news or interesting facts about a certain topic. Once ready, our system generates a response combining natural dialogue markers with queried news or facts. The response is then sent back to the Echo device where it is turned into audio signal.

Here is a video demo of Sounding Board.
