This study examined the role played by vowel quality (VQ) in perception of lexical stress by native speakers of English (E-group) and Japanese (J-group). Suprasegmental (SP) parameters and VQ parameters were independently manipulated to make stimuli. The results showed E-group identified the stress location more inaccurately in SP-only, in which the stress pattern was generated using SP parameters alone, than in SP+VQ, in which the stress pattern was generated using both SP and VQ parameters. In contrast, J-group did not differentiate between SP-only and SP+VQ. These results demonstrated E-group used VQ as a cue, whereas J-group did not use it.
