Description

We assume that SOM is adequate as a language acquisition model of the native phonetic system. However, many studies don't consider the quantitative features (the appearance frequency and the number of frames of each phoneme) of the input data. Our model is designed to learn values of the acoustic characteristic of a natural continuous speech and to estimate the number and boundaries of the vowel categories without using explicit instructions. In the simulation trial, we investigate the relationship between the quantity of learning and the accuracy for the vowels in a single Japanese speaker's natural speech. As a result, it is found that the recognition accuracy rate (of our model) are 5% (/u/)-92% (/s/).
