1.  Introduction

   This specification defines the media types of the Voice Extensible
   Markup Language (VoiceXML), the Speech Synthesis Markup Language
   (SSML), the Speech Recognition Grammar Specification (SRGS), the Call
   Control XML (CCXML), and the Pronunciation Lexicon Specification
   (PLS), the specifications of the W3C Speech Interface Framework.

   VoiceXML ([VoiceXML2.0]) is an Extensible Markup Language (XML)
   designed for creating audio dialogs that feature synthesized speech,
   digitized audio, recognition of spoken and DTMF key input, recording
   of spoken input, telephony, and mixed initiative conversations.  The
   associated media type defined in this document is
   "application/voicexml+xml".

   The Speech Synthesis Markup Language specification (SSML) defines an
   XML-based markup language for assisting the generation of synthetic
   speech in Web and other applications.  The essential role of SSML is
   to provide authors of synthesizable content a standard way to control
   aspects of speech such as pronunciation, volume, pitch, and rate,
   across different synthesis-capable platforms.  The associated media
