| Outline of Final Research Achievements |
We improved and proposed algorithms step by step with a prototype of a device which substitutes "motion of a finger" for "motion of a tongue" and in which continuous speeches are generated in real time like a musical instrument by the input with a pen or a finger on an operating panel plane.
First, we designed and improved an algorithm of the device with which a velocity of pen-input operation is complemented so that beginner users could also generate formant transitions well. And, we proposed and implemented an algorithm by which any continuous vowel sounds are generated with vocal quality similar to the short vowel sound for several seconds recorded by any speakers. Furthermore, we proposed the system which makes clear an inarticulate voice which remains in a person only with articulation disorder by inputting a motion of a pen, uttering voice. And we showed that the prototype system could generate voices similar to a speaker, keeping original prosody.
