The idea and terminology evolved from the "marking up" of manuscripts, i.e. the revision instructions by editors, traditionally written with a blue pencil on authors' manuscripts...
for annotating text input to speech synthesizers. JSML is used with-in the Java Speech API
Java Speech API
The Java Speech API specifies a cross-platform interface to support command and control recognizers, dictation systems and speech synthesizers. Although JSAPI defines an interface only there are several implementations created by third parties, for example FreeTTS.- Core technologies :Two core...
. JSML is an XML application and conforms to the requirements of well-formed XML documents. Java Speech API Markup Language is referred to as JSpeech Markup Language when describing the W3C documentation of the standard. Java Speech API Markup Language and JSpeech Markup Language identical apart from the change in name, which is made to protect Sun trademarks.
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. An example of how JSML is defined is set out below:
The W3C has developed a standard markup language SSML
Speech Synthesis Markup Language
Speech Synthesis Markup Language is an XML-based markup language for speech synthesis applications. It is a recommendation of the W3C's voice browser working group. SSML is often embedded in VoiceXML scripts to drive interactive telephony systems. However, it also may be used alone, such as for...
