In a nonword serial recall experiment we found following results: (1) Phonotactically high frequent nonwords were recalled better than low ones in terms of phoneme accuracy; (2) but this phonotactic frequency effect was not observed in accent accuracy. (3) Accent typicality did not have an expected effect on phoneme recall accuracy; (4) but it had an effect on accent accuracy. These results suggest that both long-term knowledge about phoneme sequences and accent patterns have strong influences on verbal short-term memory performance, but those influences might be limited to each particular domain.
