What is SpeakRight?
SpeakRight is an open-source Java framework for writing speech recognition applications in VoiceXML.Unlike most proprietary speech-app tools, SpeakRight is code-based. Applications are written in Java using SpeakRight's extensible classes. Java IDEs such as Eclipse provide great debugging, fast Java-aware editing, and refactoring. Dynamic generation of VoiceXML is done using the popular StringTemplate templating framework. Read more...

The StringTemplate Template Engine
SpeakRight uses StringTemplate (ST) for all its VoiceXML generation. When a flow object is rendered, it is first converted into a SpeechPage object. A SpeechPage is not VoiceXML-specific, and allows SpeakRight to output other formats such as SALT, or whatever you want. It's also the glue that ST requires. SpeechPages are rendered using one of the ISpeechPageWriter classes. For testing, an HTML page writer is available. The main page writer though is VoiceXMLPageWriter.
VoiceXMLPageWriter into VoiceXML. A StringTemplate file defines the format for prompts, grammars, fields, forms and other VoiceXML tags. This gives a lot of flexibility. If your VoiceXML platform has special requirements, simply modify the speakright.stg template file.
