Researchers examining the phonetic characteristics of a number of neutralization rules have found that underlying contrasts that should be neutralized are phonetically preserved. In particular, earlier results from a production experiment suggested that the rule of word-final devoicing in Polish is not neutralizing. The present investigation extended this work by testing whether the acoustic measures identified in productions from the original study are functional in perception. Native Polish and English listeners identified Polish monosyllabic words using a two-alternative forced-choice procedure. Results for the Polish subjects revealed better than chance performance in identifying words from the minimal pairs examined in the production study, although the magnitude of these results was less than expected. Moreover, the results suggested a bias to choose the voiceless alternative. Data obtained from English speaking subjects revealed similar results, suggesting that poor identification performance and a bias to respond with the voiceless alternative is not a function of Polish listeners’ familiarity with the rules of the language. The combined results suggest that differences in measurements obtained in the production study are not the primary cue used to distinguish reliably these items in perception.
