Voice Input: What Is the Magic and What’s Next?

Product Development

Presenter:
Paul Beckmann, DSP Concepts, Inc. - Santa Clara, CA USA

Voice user interface is being added to a myriad of products. The trend started with smart speakers but is now expanding to just about any product with a user interface: appliances, automobiles, and TVs, just to name a few. This event is a primer for product developers wanting to incorporate this feature into their products. We cover the underlying algorithms: beamforming, echo cancellation, noise reduction, and direction of arrival estimation and show how they work in concert to achieve far-field reception. The presentation combines basic theory with actual real world demonstrations in order to reinforce concepts.
