| Research Abstract |
This project investigated how various prosodic units such as moras and syllables affect production and perception of spoken language, and how they are encoded in the mental lexicon. Results showed that Japanese listeners' perception of syllables in spoken English words is not affected by the presence of katakana loanwords that diverge prosodically from the source words. Also, second-language learners' perception of length contrasts in Japanese improves to some extent as a result of perceptual training and language experience, but they have difficulty approaching native-like performance. Finally, the functional load of phonemes, which measures how much each phoneme contributes to distinguishing words, was found to be more useful when it is defined with reference to the prosodic structure of words such as their word accent pattern. Altogether, these results suggest that prosodic units are psychologically real and critically affect perception and production of spoken language.
