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 ready-made 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 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.
