* Welcome! [#k4f3be02]
 > The [[HMM-based Speech Synthesis System (HTS)>http://hts.sp.nitech.ac.jp/]] has been being developed by the HTS working group and others (see [[Who we are]] and [[Acknowledgments]]).  The basic core system of HTS is implemented as a modified version of [[HTK:http://htk.eng.cam.ac.uk/]] and released as a form of patch code to HTK.  The patch code is released under a free software license similar to the [[MIT License:http://en.wikipedia.org/wiki/MIT_License]].  However, it should be noted that &color(red){once you apply the patch to HTK, you must obey the [[license of HTK:http://htk.eng.cam.ac.uk/docs/license.shtml]].};
 
 > In HTS version 2.0.1, many bugs in HTS version 2.0 were fixed.  API version of hts_engine, hts_engine_API, version 0.9 was also released.  HTS and hts_engine_API have not included any text analyzer yet, but you can use the [[Festival Speech Synthesis System:http://www.festvox.org/festival/]] as a text analyzer. This distribution includes demo scripts for training speaker-dependent and speaker-adapted systems using [[CMU ARCTIC database:http://www.festvox.org/cmu_arctic/]] (English).
 Six HTS voices for Festival 1.95 and 1.96 are also released. They are based on our small synthesis engine called '''hts_engine''' which has been included as a module of Festival.  Each of HTS voices can be used without any other HTS tools.
 
 > For training Japanese voices, a demo script using the Nitech database is also prepared.  Japanese voices trained by the demo script can be used on [[GalateaTalk:http://hil.t.u-tokyo.ac.jp/~galatea/]], which is a speech synthesis module of an open-source toolkit for anthropomorphic spoken dialogue agents developed in [[Galatea project:http://hil.t.u-tokyo.ac.jp/~galatea/]].  An HTS voice for Galatea trained by the demo script is also released.

 * News! [#ve28e7f9]
 - ''June 13, 2008''
 > HTS version 2.1RC2 and hts_engine API version 0.99 were released to the hts-users ML members.~
 See [[here:http://hts.sp.nitech.ac.jp/hts-users/spool/2008/msg00336.html]] for details.
 
 - ''May 27, 2008''
 > HTS voice building tools for the MARY platform was released with [[DFKI MARY 3.6.0:http://mary.dfki.de/Download/mary-3-6-0-released]].
 
 - ''March 24, 2008''
 > HTS version 2.1RC1 and hts_engine API version 0.96 were released to the hts-users ML members.~
 See [[here:http://hts.sp.nitech.ac.jp/hts-users/spool/2008/msg00175.html]] for details.
 
 // - ''January 15, 2008''
 // > HTS version 2.1beta and hts_engine API version 0.95 were released to the hts-users ML members.
 
 // - ''December 7, 2007''
 // > hts_engine was ported to Java and included in [[DFKI MARY 3.5:http://mary.dfki.de/Download/mary-3-5-0-released]]. 
 
 // - ''November 1, 2007''
 // > HTS version 2.1alpha was released to the hts-users ML members.
 // - ''October 1, 2007''
 // > HTS version 2.0.1 and hts_engine_API version 0.9 were released.~
 // The new features are
 // - Many bug fixes.
 // - Band structure for linear transforms.
 // - Stream-dependent variance flooring scales.
 // - State duration model mmf structure is changed.  In the previous versions we // used a multi-variate Gaussian PDF to represent state duration PDFs of an HMM.     // However, from this version we use multi-stream structure.  This is very important for the future HSMM support.
 // - Demo scripts support LSP-type parameters for spectral representation in addition to cepstral ones.
 // - API-style implementation of hts_engine.  Old stand-alone hts_engine will be thrown away.
 
 // - ''September 20, 2007''
 // > HTS version 2.0.1RC1 was released to the hts-users ML members.
 
 // - ''September 18, 2007''
 // > HTS version 2.0.1RC1 was released to the internal working group members.
