Research Topics - Speech Synthesis

Introduction

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

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

Text To Speech (TTS)

It is technology to synthesize a sound from an arbitrary text.

Speaker Interpolation

It is technology to create the models of a new speaker by putting the model of plural speakers together．

Eigen Voice

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

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

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

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.
