This book is for those professional developers who wish to add a new language to their toolkit, and want to be in a position to take advantage of the imminent explosion in voiceenabled applications. We assume a prior knowledge of XML, and some other web programming technologies, such as ASP, JSP and PHP. VoiceXML brings the power of Voice to the Web the information we are used to accessing through the visual web interfaces of our PCs 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 portals available. With the world`s billion plus telephones, from antique black candlestick phones to the latest mobiles, there is a huge readymade audience crying out for voice applications. The userbase encompases those on the move who require easy access to information wherever they are, and those who haven`t the money or inclination to access the Internet through a PC. The book aims to give the reader an indepth analysis of the current state of VoiceXML technology. The information will help you develop voiceenabled applications now, and make sure you are ready for future advances of this quickly changing arena.
