Abstract
Google search by Voice is a free application from Google that allows spoken access to google.com. We currently support Apple iPhone, Android, Blackberry and Nokia Series 60 devices. In this talk we will give an overview of Google Search by Voice and our efforts to make speech input on mobile devices truly ubiquitous. We describe the basic technology behind Google search by Voice. In particular we focus on the unique set of challenges faced while building Google search by Voice, ranging from cloud computing, speech recognition, natural language processing and user interface design, as well as a collection of important open research challenges in these realms.
