Summary
This chapter introduced you to a telephony application of XML known as VoxML, which was created by Motorola to facilitate the creation of interactive speech applications. VoxML is a significant improvement over the current approaches to building voice response systems. It's also an interesting merging of technologies, using XML alongside voice synthesis and voice recognition engines. XML gives VoxML a certain simplicity that is quite powerful, considering how much is involved in generating speech from text and then processing spoken responses from the user. VoxML may be the technology that moves us beyond the traditional voice response systems that ask you to "Press 2 for this" and "Press 9 for that."
