Perceptually Easy Second-Language Phones Are Not Always Easy: The Role of Orthography and Phonology in Schwa Realization in Second-Language French.

Abstract

Encoding and establishing a new second-language (L2) phonological category is notoriously difficult. This is particularly true for phonological contrasts that do not exist in the learners' native language (L1). Phonological categories that also exist in the L1 do not seem to pose any problems. However, foreign-language learners are not only presented with oral input. Instructed L2 learning often involves heavy reliance on written forms of the target language. The present study investigates the contribution of orthography to the quality of phonolexical encoding by examining the acoustics of French schwa by Austrian German learners-a perceptually and articulatorily easy L2 phone with incongruent grapheme-phoneme correspondences between the L1 and L2. We compared production patterns in an auditory word-repetition task (without orthographic input) with those in a word-reading task. We analyzed the formant values (F1, F2, F3) of the schwa realizations of two groups of Austrian high-school students who had been learning French for 1 and 6 years. The results show that production patterns are more likely to be affected by L1 grapheme-to-phoneme correspondences when orthographic input is present. However, orthography does not appear to play the dominant role, as L2 development patterns are strongly determined by both the speaker and especially the lexical item, suggesting a highly complex interaction of multiple internal and external factors in the establishment of L2 phonological categories beyond orthography and phonology.
