As part of a research project on the investigation of second language (L2) ultimate attainment in 41 Spanish early and late near-native speakers of L2 Swedish, the present study reports on voice onset time (VOT) analyses of the production of Swedish word-initial voiceless stops, /p t k/. Voice onset time is analyzed in milliseconds as well as in percentages of word duration, thereby accounting for speaking rate effects. The results revealed an overall age effect on VOT production; however, this age effect became salient and statistically significant for all three stops only when speaking rate was taken into consideration. Similarly, when speaking rate was accounted for, only a small minority of the late learners exhibited actual nativelike L2 behavior, and most (but far from all) early learners performed within native-speaker range. The results are taken as an indication for relative VOT, as opposed to absolute VOT, constituting a reliable measure of nativelike L2 stop production, which has important implications for future research on age effects and maturational constraints in L2 acquisition.
