This paper investigates whether perception of coarticulatory effects, specifically the spectral effects exerted on and by adjacent segments, is influenced by one's L1. Four continua, [ʃu:ʃ] - [ʃi:ʃ], [ʃaʃ] - [ʃɛʃ] and their isolated vowel counterparts, were presented as native language sounds to North American English and Catalan speakers. Lip rounding, associated with a lowering of the second and third formants, is a typical feature of alveolo-palatal fricatives in English, but not in Catalan. Thus, if listeners' identification of the speech signal is in fact influenced by their L1, we expect that Catalans will perceive more back vowels in a lip rounded [ʃVʃ] context than Americans, who should perceive more front vowels. Additionally, Americans are expected to show similar identification curves for the two conditions, while Catalans should show different curves: reporting more back vowels in context than in isolation. Resulting trends support these predictions.
