Editing Java Speech Markup Language

{{Short description|XML-based markup language}}{{More citations needed|date=May 2024}}

'''Java Speech API Markup Language''' ('''JSML''') is an [[XML]]-based [[markup language]] for annotating text input to [[speech synthesizer]]s.  JSML is used within the [[Java Speech API]]. 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 was developed by Andrew Hunt at [[Sun Microsystems]].<ref name=":0">{{Cite book |last=Taylor |first=Paul |title=Text-to-Speech Synthesis |date=2009 |publisher=Cambridge University Press |isbn=9780521899277 |pages=68–69}}</ref>

== 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. 

== Example ==
An example of how JSML is defined is set out below:<syntaxhighlight lang="xml">
<jsml> 
  <div type="paragraph">This block about <literal>JSML</literal> is constructed as
  a <emphasis><literal> JSML </literal></emphasis> example.</div> 
</jsml>
</syntaxhighlight>

== Related standards ==
JSML built on the original proposal for a [[Speech Synthesis Markup Language|speech synthesis markup language]] (SSML), a set of general markup tags that could be used across different [[Speech synthesis|text-to-speech (TTS) systems]].<ref name=":0" />

The [[W3C]] developed a standard markup language called [[VoiceXML]], also often referred to as SSML, which is based on [[JSML]] but is not identical to it.<ref name=":0" /> This became a formal [[W3C recommendation]] in 2004.
