The StringTemplate template engine is a popular choice for generating markup text in Java. It comes from Terrence Parr, the inventor of ANTLR.
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.
