* Research Topics - Speech Synthesis [#m6b8da40] //&ref(speechsynthesis.jpg,nolink,center,40%); ** Introduction [#o2a165e8] > The speech synthesis is technology to 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 it models quantity of characteristic to be included in a sound statistically and synthesize a sound. ** Research Field [#k18cf145] *** Text To Speech (TTS) [#z66e5bde] > It is technology to synthesize a sound from an arbitrary text.~ *** Speaker Interpolation [#d3c8bafc] > It is technology to create the models of a new speaker by putting the model of plural speakers together.~ [[demonstration page>HOME/DEMONSTRATION/SPEAKER INTERPOLATION]] *** Eigen Voice [#o28cbc54] > 複数の話者や話し方のスタイルを少量のパラメータによるモデル空間で表し, それらのパラメータに重み付けすることで任意の声質を表現して音声を合成する 技術です.~ 様々は声質,話し方を生み出すことができます. *** Singing Voice Synthesis [#x08960e4] > It is technology to synthesize 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] > It is technology to convert the sound of a certain speaker into as if the sound of another speaker.~ It 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] > It is technology to convert 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.
