Research Abstract

Using magnetic resonance imaging techniques, we explored brain activity during the speech production of unfamiliar foreign speech sounds in children (from child to adolescent), and the developmental changes. We also examined the relationship between the ability of foreign speech sound production and brain structure. In results, it was found that there were almost no difference in brain activity during speech production task between foreign and native speech sounds in younger children, however the difference became clearer withage, and that the degree of accuracy of foreign speech sound production gradually improved with age. Furthermore, we found a significant correlation between the degree of accuracy of foreign speech sound production and children's brain structure.
