Web Page Analysis for Voice Browsing

Voice User Interfaces (VUI's) are rapidly evolving to include Web based content. The primary motivations are: to provide a widely available means for creating new interactive voice applications; addressing needs for mobility; and addressing issues in accessibility. Much of this activity has focused on creating new markup languages like VoiceXML, now being standardized by the W3C Voice Browser Working Group. However, today there is a very large investment in legacy HTML content that can be automatically converted to produce a voice dialog interface to content not originally intended for voice access. We will describe two approaches, telephone browsing and transcoding, focusing mostly on the former since that work is more mature.
