| Research Abstract |
By examining the recordings of super learners of Japanese as L2, the following implications were obtained.
(1)Even for the super learners the precise realization of pitch patterns of words which are relatively less frequently used seem to be difficult.
(2)In the production of Japanese speech sounds by super learners, it seems that they tend to shorten the long vowels in word final positions more than non-word-final position ones. This is the same tendency that the native speakers of Japanese show and this fact implies that implicit linguistic rule might be learnable even after so called the critical period.
Through the research was found quite hard to definitely categorize short vowels and long vowels even using acoustical analysis instruments such as Multi Speech or Sugi Speech. It is an important task for researchers of learner speech analysis to establish a certain commonly accepted way of judging whether the vowel is short or long phonologically.
Second question that remained was the adequacy of the application of interlanguage theory to the various phenomena of speech sound acquisition. Following what was brought to light through this research, it is necessary to start collecting more reliable data longitudinally to scientifically examine the relation between the data and the theory.
