Building on the results of a previous study, reiterant speech is used to test a number of durational characteristics of a stress-timed language (English), a syllable-timed language (Spanish) and a mora-timed language (Japanese). The results indicate that moras and stress feet do influence syllable duration in their respective languages, Japanese and English. Spanish, however, seems to show no language-specific durational characteristics which could be claimed to be indicative of syllable timing.
