VoiceXML brings the power of voice to the Web - the information we are used to accessing through the visual web interfaces of our PC and mobile devices can now be accessed through speech alone. Building on the functionality already seen in IVR applications deployed by our banks and utility companies, the tag based syntax of VoiceXML will instantly be familiar to existing web developers, and applications can already be deployed using one of the many voice gateways available. The book aims to give the reader an in-depth analysis of the current state of VoiceXML technology. The information will help you develop voice-enabled applications now, and make sure you are ready for future advances of this quickly changing arena. Who is this book for? This book is for those professional developers who wish to add a new 1anguage to their toolkit, and want to be in a position to take advantage of the imminent explosion in voice-enabled applications.
