* [[Acknowledgments]] [#v999b499] The following people and related organizations have contributed to the development of HTS in various ways. It is their work that makes it all possible. In no special order: - ''Keiichi Tokuda'' (current member)~ Overall concept and design. - ''Keiichiro Oura'' (current member)~ Implementation of hts_engine API. He is the current maintainer of HTS. ** Since HTS-1.0 [#o6ad4a9a] - ''Heiga Zen'' (current member)~ Throwing away all old codes of HTS and rewriting them as HTS version 1.0, 1.1, 1.1b, 1.1.1, 2.0, 2.0.1, and 2.1. - ''Junichi Yamagishi'' (current member)~ Testing out various clustering and adaptation algorithms. Implementation of the CSMAPLR adaptation algorithm. - ''Takayoshi Yoshimura'' (ex. member)~ Development of the first version of HTS. - ''Masatsune Tamura'' (ex. member)~ Implementation of various speaker adaptation algorithms for HMM-based speech synthesis. - ''Shinji Sako'' (current member)~ Applying HMM-based speech synthesis to audio-visual speech. - ''Noboru Miyazaki''~ Implementation of the first version of MSD-HMM trainer for pitch pattern modeling. - ''Tetsuya Yamada''~ Testing out various HMM training algorithms for HMM-based speech synthesis. - ''Takashi Masuko'' (ex. member)~ Discussions in detail and implementing speech parameter generation algorithms. - ''Takao Kobayashi''~ Discussions and supervising students working on speech synthesis. - ''Tadashi Kitamura''~ Discussions and supervising students working on speech synthesis. - ''Satoshi Imai''~ Supervising students working on speech synthesis. - ''Alan Black'' (current member)~ Discussions about all aspects of speech synthesis, helping us to use Festival, and supplying speech databases. ** Since HTS-2.0 [#oadca1a9] - ''Takashi Nose'' (current member)~ Testing out the version 2.0. ** Since HTS-2.0.1 [#z4a66e7a] - ''Tomoki Toda'' (current member)~ Discussions and implemantation of GV-based parameter generation algorithms. //** Since HTS-2.1.1 //- ''Kei Hashimoto'' (current member)~ //... ** Special thanks [#md56a172] - ''Steve Young, Phil Woodland, Mark Gales, Gunnar Evermann, and other HTK developers''~ Development of [[HTK>http://htk.eng.cam.ac.uk/]]. and many other important contributors (we had to leave them out since they are too many).
