** Introduction [#o2a165e8]
> The speech synthesis is technology that let a computer do natural utterance like the human being.~
We push forward a study to make more fluent and natural utterance.
** HMM Speech Synthesis [#u1f78200]
> Various technique such as the unit choice type is suggested to a voice synthesis, but we treat technique based on a statistical frame such as Hidden Markov model (HMM) mainly in our laboratory.~
The HMM speech synthesis system is based on HMM, and this models quantity of characteristic to be included in a sound statistically and synthesize a sound.
** Research Field [#k18cf145]
*** Text Speech Synthesis [#z66e5bde]
> This is technology that synthesizes a sound from an arbitrary text.~
This is called Text to Speech (TTS) too.
*** Speaker Interpolation [#d3c8bafc]
> This is technology that creates the models of a new speaker by putting the model of plural speakers together．~

*** Eigen Voice [#o28cbc54]
> This is technology that expresses plural speakers and styles of the speech in model space by a little parameter and synthesizes the sound of arbitrary quality of voice by adding heaviness to those parameters.
*** Singing Voice Synthesis [#x08960e4]
> This is technology that synthesizes an arbitrary song by giving a text and score.~
We can expect various uses in the field of entertainment and the amusement.
*** Speech Convertion [#d7027006]
> This is technology that converts the sound of a certain speaker into as if the sound of another speaker.~
This learns models from the utterance data of two speakers and converts the utterance data of one speaker into the data of other speaker.
*** Speaker Adaptation [#g8d70d7f]
> This is technology that converts the quality of voice of the aim speaker by converting a model parameter of HMM from a little data of the speaker of the aim.
