“…Vowel onset was measured from the onset of periodicity following the release burst of the stop. Vowel offset was located at the point where the amplitude dropped significantly (Fox and Jacewicz, 2009;Jacewicz et al, 2011) and at the last well-formed period of the vowel (Colantoni et al, 2015b), though these were not always the same. In those cases where the vowel offset was followed by a word beginning with a vowel, it was located at the point in the spectrogram where the first formant of the second vowel rose.…”

Stress-Induced Acoustic Variation in L2 and L1 Spanish Vowels

Aim: We assessed the effect of lexical stress on the duration and quality of Spanish word-final vowels /a, e, o/ produced by American English late intermediate learners of L2 Spanish, as compared to those of native L1 Argentine Spanish speakers. Methods: Participants read 54 real words ending in /a, e, o/, with either final or penultimate lexical stress, embedded in a text and a word list. We measured vowel duration and both F1 and F2 frequencies at 3 temporal points. Results: stressed vowels were longer than unstressed vowels, in Spanish L1 and L2. L1 and L2 Spanish stressed /a/ and /e/ had higher F1 values than their unstressed counterparts. Only the L2 speakers showed evidence of rising offglides for /e/ and /o/. The L2 and L1 Spanish vowel space was compressed in the absence of stress. Conclusion: Lexical stress affected the vowel quality of L1 and L2 Spanish vowels. We provide an up-to-date account of the formant trajectories of Argentine River Plate Spanish word-final /a, e, o/ and offer experimental support to the claim that stress affects the quality of Spanish vowels in word-final contexts.

“…Early models of L2 speech perception, such as the Speech Learning model or SLM (Flege, ; Flege, Schirru, & MacKay, ) and the Perceptual Assimilation Model or PAM (Best, ) and its extensions PAM–L2 (Best & Tyler, ) and PAM–S (So & Best, , ), were designed to capture the initial stage of L2 learning in which learners lacked sufficient lexical representations and had limited experience with the target language and its statistical regularities. While these models have considerably advanced our understanding of L2 perception and learning of nonnative speech sounds (for an overview, see Colantoni, Steele, & Escudero, ), they were not explicitly designed to test hypotheses involving statistical learning and its effect on L2 speech perception.…”

Statistical Regularities Affect the Perception of Second Language Speech: Evidence From Adult Classroom Learners of Mandarin Chinese

2019

This study investigated how adult second language (L2) learners of Mandarin Chinese use knowledge of phonological and lexical statistical regularities when acoustic information is insufficient for word recognition. A gating task was used to test intermediate L2 learners at two time points across a semester of classroom learning. Native Mandarin speakers (tested once) served as a control group. Mixed-effects modeling revealed that upon hearing truncated speech, L2 learners, like native speakers, identified high token frequency syllable-tone combinations more accurately than low token frequency syllable-tone combinations. Error analysis of correct syllable/incorrect tone responses revealed that native speakers made specific probability-based errors. L2 learners primarily demonstrated more acoustic-based errors but exhibited a trend toward greater probability-based errors during the second test. These findings are interpreted in light of L2 speech learning models that emphasize a statistical learning mechanism.

“…The effects of L1 on L2 speech production are well documented (Colantoni & al. 2015), and, in particular, a number of researchers found effects of L1 on L2 Voice Onset Time (VOT).…”

Recent research has revealed the effects of orthography on the pronunciation of consonant durations in the L2 English of L1 Italian speakers (e.g. the [p] in floppy being pronounced as longer than in copy). In this paper we compared this orthographic effect with an orthography-independent effect of L1 phonology, namely VOT. We measured closure durations and VOT for plosives produced by 30 learners of L2 English in Italy, 30 Italian late bilingual speakers of L2 English living in the UK, and 30 native English speakers. While VOT values produced by late bilinguals differed significantly from those produced by learners, closure durations were similar across the two groups. Additionally, L1 Italian VOT values proved that late bilinguals adapted VOT in L2 English by a larger extent than learners. It appears that the effects of orthography on L2 consonant duration can be more resistant to naturalistic L2 exposure than orthography-independent effects of L1 phonology. RésuméDes recherches récentes ont dévoilé les effets de l'orthographe sur la durée consonantique en anglais L2 de locuteurs natifs italiens (le [p] étant réalisé plus long pour floppy que pour copy). Nous avons comparé cet effet orthographique avec un effet de la phonologie de la L1 indépendant de l'orthographe, le Voice Onset Time (VOT). La tenue et le VOT d'occlusives dans des mots-cibles ont été mesurés chez 30 apprenants d'anglais L2 en Italie, 30 bilingues tardifs italiens résidant au Royaume Uni et 30 locuteurs natifs d'anglais. Si les valeurs de VOT produites par les bilingues se différencient de manière significative par rapport à celles des apprenants, les valeurs de tenue restent comparables dans les deux groupes. En outre, le taux d'adaptation du VOT en anglais L2 est plus important chez les bilingues tardifs que chez les apprenants. Cela prouve que les effets orthographiques sur la longueur consonantique peuvent être plus résistants à l'exposition de la L2 que les effets de la phonologie de la L1 indépendants de l'orthographe.
