Perception of place and secondary articulation contrasts in different syllable positions: language-particular and language-independent asymmetries.

This study investigated the perception of place and secondary articulation contrasts in different syllable positions by Russian and Japanese listeners. The consonants involved in the study were the Russian plain (velarized) and palatalized labial and coronal voiceless stops in syllable-initial and syllable-final positions at word boundaries. The findings revealed substantial asymmetries in the perception of the contrasts by both groups of listeners: With respect to positions, consonants in syllable-final position were characterized by lower correct identification rates and (less consistently) longer reaction time than the same consonants in syllable-initial position. Positional syllable position differences were accompanied by differences in segment-specific contexts. With respect to individual consonants, the palatalized labial /p(j)/ and the plain coronal /t/ showed a lower correct identification rate and smaller perceptual distance than the plain labial /p/ and the palatalized coronal /t(j)/. The results also showed some differences between Russian and Japanese listeners in the perception of the contrast. These differences can be explained by phonotactic differences between the two languages, as well as by differences in the phonetic realizations of the consonants. The results of the study provide evidence for the role of both universal and language-particular factors in speech perception.
