Abstract (in Japanese) (See Japanese page) 
(in English) We propose a model of infant’s word acquisition by speech mimicking. We use vowel space parameter representing a gesture of articulation. The coarticulation is expressed in Fujisaki model applied to the vowel space parameters. The trial and error in the speech mimicking is modeled in the genetic algorithm. The gesture of articulation is detected as “a command” of Fujisaki model from the ambiguous spectrum. We show the effectiveness of the model by listening tests and detection of the gesture of articulation from the symmetric three vowels and the cut two vowels.
