This is a feature release, adding new features while maintaining compatibility with existing 4.0 voices.

New features for expressive TTS

  • Prosody control for HMM-based voices. Using the SSML ​<prosody> tag, it is now possible to control the intonation generated for HMM-based voices from markup.
    Of particular interest is the "contour" attribute, which allows you to change the shape of the intonation curve.
    For details and examples, see ProsodySpecificationSupport.
  • Expressive vocalizations in certain unit selection voices.
    MaryXML now supports a new <vocalization> tag, with which you can request the generation of non-verbal or para-verbal expressions as they are often produced by the listener in a conversation, such as "yeah", "m-hm", laughter, sigh, etc.
    For details and examples, see VocalizationSynthesis.

New voices

  • For British English, we release HMM-based versions of the four voices Poppy, Spike, Obadiah and Prudence.
  • Updated versions of many of the previously existing voices, with improved quality.
