In an industry dominated by expensive proprietary tools, open-source software offers some enticing benefits. The SpeakRight Framework is a new open-source Java framework for writing VoiceXML applications. It offers a high-level API and re-usable classes. And since you have the source code, it's totally extensible.
SpeakRight is code-based. You write your application in Java using SpeakRight classes, with all the power and convenience of Java debugging, refactoring, and unit tests. And unlike other web frameworks, SpeakRight is built specifically for VoiceXML and speech recognition applications. It understands prompt escalation, grammars, and confirmation. When asked to write a speech application, many developers are tempted to output the raw VoiceXML tags themselves. This works in simple cases, but once you add all the elements of a voice dialog, even a simple question involves many tags. Speech applications must deal with the inherent inaccuracy of speech recognition: retrying if recognition fails and confirming when recognition's confidence score is low.
