Developing Voice XML Speech Applications

This course highlights the syntactic structure and 40+ tags of VoiceXML 2.0, the standard for speech services. During the course you will develop your own application by implementing prompt and grammar alternatives, forms, menus, and subdialogs. You will utilize logical branching elements, variables, and error handling elements. You gain an understanding of the architecture in which VXML applications run. You learn best practices for streamlining application code. Participants attend class from their own PC and will need Web access to the following sites:

• http://nlc.nuance.com
