VoiceXML 2.0 Certification Training
VoiceXML 2.0 Certification Training is a 4 day, instructor-led course that stresses VoiceXML application development, including an introduction to ECMAScript and Speech Recognition Grammar development.
In addition, this course includes an entire day devoted to technical details and related topics to prepare students for the VoiceXML Application Developer Certification exam, including:
- Speech Synthesis Markup Language
- Speech Recognition Grammar Language
- Semantic Interpretation Language
- ECMAScript
- Call Control XML Language
Each module lasts approximately one hour, and is followed by a programming lab to enhance the student’s understanding and debugging skills
The classroom environment equips each student with a full development PC with VoiceXML, Speech Recognition, Text-to-Speech, and a SIP SoftPhone for immediate development and testing of their code.
VoiceXML topics introduced and practiced in this class include:
- Describing the role of VoiceXML applications in a Web-server based environment
- Understanding the syntax rules of XML that pertain to VoiceXML
- VoiceXML programming topics:
- Playing text-to-speech and streaming audio to deliver caller information
