Usage

JSML is primarily an XML text format used by Java applications to annotate text input to speech synthesizers. Elements of JSML provide speech synthesizer with detailed information on how to speak text in a naturalized fashion. JSML defines elements which define a document's structure, the pronunciation of certain words and phrases, features of speech such as emphasis and intonation, etc. JSML is designed in the Java fashion to be simple to learn and use, to be portable across different synthesizers and computing platforms, and although designed for use within is also applicable to a wide range of languages.
