== Support for explicit prosody specifications ==

 MARY TTS support explicit prosody specification using 'prosody' element as described in [http://www.w3.org/TR/speech-synthesis11/#edef_prosody W3C Speech Synthesis Markup Language (SSML) 1.1 recommendation]; and the different attributes in 'prosody' element like 'rate', 'pitch' and 'contour' are used as specifications to modify predicted phone durations and pitch contour before passing them to synthesizer.

'''Note:''' The following examples will only work if the `INPUT_TYPE` is set to `RAWMARYXML`. HSMM voices are able to realize the specified prosody out of the box; for unit selection voices, at least MARY 4.3.0 is needed, and the checkbox "Apply prosody modification" must be activated in the [http://mary.dfki.de:59125 web interface].

 Example: 
 
 {{{
 <?xml version="1.0" encoding="UTF-8" ?>
 <maryxml version="0.4"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns=" http://mary.dfki.de/2002/MaryXML"
  xml:lang="en-US">
   <p>
    <prosody rate="fast" pitch="+10%" contour="(10%,low)(50%,-20%)(80%,+10%)(100%,+5st)">
     Welcome to the world of speech synthesis!
    </prosody>

=== Adjusting Speech Rate ===
  
 Example 1: 
 
  {{{
 <?xml version="1.0" encoding="UTF-8" ?>
 <maryxml version="0.4"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns=" http://mary.dfki.de/2002/MaryXML"
  xml:lang="en-US">
   <p>
    <prosody rate="200%">
      I am now speaking twice as fast.
    </prosody>
   </p>
 </maryxml>
 }}}

 Example 2:

  {{{
 <?xml version="1.0" encoding="UTF-8" ?>
 <maryxml version="0.4"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns=" http://mary.dfki.de/2002/MaryXML"
  xml:lang="en-US">
   <p>
    <prosody rate="70%">
     I am now speaking 30% more slowly.
    </prosody>
   </p>
 </maryxml>
 }}}


=== Adjusting Pitch level ===

 Example 1: 
 
  {{{
 <?xml version="1.0" encoding="UTF-8" ?>
 <maryxml version="0.4"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns=" http://mary.dfki.de/2002/MaryXML"
  xml:lang="en-US">
   <p>
    <prosody pitch="low">
      I am now speaking with 3/4 pitch.
    </prosody>
   </p>
 </maryxml>
 }}}

 Example 2:

  {{{
 <?xml version="1.0" encoding="UTF-8" ?>
 <maryxml version="0.4"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns=" http://mary.dfki.de/2002/MaryXML"
  xml:lang="en-US">
   <p>
    <prosody pitch="-5st">
     This is five semitones lower.
    </prosody>
   </p>
 </maryxml>
 }}}


=== Shaping intonation contour ===

 Example 1:
 
 {{{
 <?xml version="1.0" encoding="UTF-8" ?>
 <maryxml version="0.4"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns=" http://mary.dfki.de/2002/MaryXML"
  xml:lang="en-US">
   <p>
    <prosody contour="(0%,x-low)(30%,low)(50%,medium)(70%,high)(100%,x-high)">
     I am talking with rising intonation.
    </prosody>
   </p>
 </maryxml>
 }}}

 Example 2:
 
 {{{
 <?xml version="1.0" encoding="UTF-8" ?>
 <maryxml version="0.4"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns=" http://mary.dfki.de/2002/MaryXML"
  xml:lang="en-US">
   <p>
    <prosody contour="(0%,+5st)(30%,+2st)(50%,+0.1st)(70%,-3st)(100%,-6st)">
     I am talking with falling intonation.
    </prosody>
   </p>
 </maryxml>
