Abstract (in Japanese) (See Japanese page) 
(in English) We propose the phoneme acquisition model that simulates human auditory system that perceives the temporal variations of the speech. Our model is designed to learn values of the acoustic characteristic of a continuous speech and to estimate the number and boundaries of the phoneme categories without using explicit instructions. A purpose of this study is to clarify the role of an Infant-Directed Speech (IDS), that has the high variability. We performed a learning experiment of an Adult Directed Speech (ADS) and IDS using our model and compared the results. As a result, in the accuracy rate of the voiceless stops, IDS is significantly higher than ADS. Accordingly, it is possible that IDS emphasized the acoustic features of unsteady phonemes, and to assist the acquisition.
