AbstractThis paper offers an analysis of various typologies of speech rhythm with a Second Language Acquisition (SLA) perspective. The notion of isochrony and the enduring stress- and syllable-time theory are shown to be perception-, rather than production-, related. Duration-centered statistical approaches are found to measure phonotactics rather than establish a functional typology. It is further argued that no existing rhythmic typology can be recognized as efficiently organizing data to enable grouping and comparison of languages, a highly coveted tool in SLA. The outline of an SLA relevant classification, taking into account phonological elements and phonetic processes, is sketched.
