Abstract (in Japanese) (See Japanese page) 
(in English) When individuals with speaking disabilities, dysarthrics, want to communicate using speech, they often use speech synthesizers which require them to type word symbols or sound symbols. This input method often makes realtime operations difficult and dysarthric users fail to control the flow of conversation. In this paper, a new and novel speech synthesizer is proposed where not symbol inputs but hand motions are used to generate speech. In recent years, statistical voice conversion techniques have been proposed based on space mapping. By applying these methods, a hand motion space and a vowel space is mapped and a convertor from hand motions to vowel transitions is developed. In this paper, as a preliminary discussion, the correspondence between Japanese five vowels and five hand gestures is fixed so that a transition between any pair of vowels will not generate a third vowel. Using this correspondence, we develop a converter, which will convince us that the conversion is effective enough. After this preliminary discussion, we make attempts to find a more optimal correspondence between hand gestures and vowels. By considering the equivalence between geometrical features of the gestural arrangement in the gesture space and those of the vowel arrangement in the vowel space, we show that the quasi optimal correspondence can be obtained.
