Details Aiming at establishing a design methodology of voice attributes to facilitate understanding, affection, alert and safety feeling by non-linguistic voice aspects, this research project was conducted. It was based on a de facto standard speech research framework STRAIGHT, developed by the prime investigator and yielded several useful research tools. A highly accurate and computationally efficient F0 extractor with higher temporal resolution than conventional methods is an example of such extension and development. In this course of investigations, a revolutionary new morphing framework was invented. The new method is capable of morphing arbitrary many voice examples in one shot procedure with individual control of each physical speech parameter and enabled time dependent weight setting. This new morphing method and other research products of the project provides basis of the substantially new research project.
