Auditory and Acoustic Evidence for Palatalization of the Nasal Consonant in Cairene Arabic

This paper introduces the palatalized nasal [nʲ] as an allophonic realization of coronal /n/ in Cairene Arabic. The palatalized variants of the phonemes previously described in acoustic and sociolinguistic terms include the alveolar stops [t, d] and their pharyngealized counterparts [tˤ, dˤ], which can be palatalized preceding the high, front vowel [i:]. While previous studies have anecdotally noted that the coronal nasal /n/ can undergo palatalization in the same environment, this variant has not been systematically investigated. Focusing on syllable-final /-ni:/ segments, I first use auditory measures to show that the palatalized variant occurs with some regularity (~50%) in the read speech of seven speakers of Cairene Arabic. Then, I provide acoustic evidence that this perceived difference significantly correlates with the difference in F2 values taken from the onset and midpoint of the vowel following the nasal consonant. There is also evidence of a lexical effect, such that borrowings exhibit less palatalization than non-borrowings. This study contributes data for the unexamined Cairene nasal and supports the likelihood of palatalization of coronals at the typological level.

How Do Speakers of a Language with a Transparent Orthographic System Perceive the L2 Vowels of a Language with an Opaque Orthographic System? An Analysis through a Battery of Behavioral Tests

Background: The present study aims to investigate the effect of the first language (L1) orthography on the perception of the second language (L2) vowel contrasts and whether orthographic effects occur at the sublexical level. Methods: Fourteen adult Greek learners of English participated in two AXB discrimination tests: one auditory and one orthography test. In the auditory test, participants listened to triads of auditory stimuli that targeted specific English vowel contrasts embedded in nonsense words and were asked to decide if the middle vowel was the same as the first or the third vowel by clicking on the corresponding labels. The orthography test followed the same procedure as the auditory test, but instead, the two labels contained grapheme representations of the target vowel contrasts. Results: All but one vowel contrast could be more accurately discriminated in the auditory than in the orthography test. The use of nonsense words in the elicitation task eradicated the possibility of a lexical effect of orthography on auditory processing, leaving space for the interpretation of this effect on a sublexical basis, primarily prelexical and secondarily postlexical. Conclusions: L2 auditory processing is subject to L1 orthography influence. Speakers of languages with transparent orthographies such as Greek may rely on the grapheme–phoneme correspondence to decode orthographic representations of sounds coming from languages with an opaque orthographic system such as English.

Variable subject pronoun expression revisited: This is what the Paisas do

We explore subject pronoun expression (SPE) in Medellín, Colombia using 4,623 tokens to test eight predictors. The 28% overall pronominal rate found is significantly higher than those in other mainland communities. Grammatical person exerts the greatest conditioning effect, with uno ‘one’ strongly favoring overt subjects. Findings for verb class reveal that speech and cognitive verbs promote overt subjects. However, our in-depth analysis unveils opposing tendencies between different pronominal subject + verb collocations for the same verb. E.g., whereas (yo) soy ‘I am’ strongly favors overt subjects, (ellos) son ‘they are’ favors null subjects. These findings suggest that analyses focusing on infinitives do not constitute the most accurate way to explore verb effects on SPE. Moreover, the effect of age reveals a low pronominal rate among the youngest speakers, a finding that appears to have cognitive and acquisitional implications, as younger speakers would be expected to have higher pronominal rates. In general, this study contributes to expand our knowledge of SPE. Further, the findings regarding age and the lexical effect of the verb open promising research paths.

A Variationist Study of Subject Pronoun Expression in Medellín, Colombia

This variationist study of subject pronoun expression (SPE) in Medellín, Colombia uses multivariate regressions to probe the effects of ten predictors on 4623 tokens from the Proyecto para el Estudio Sociolingüístico del Español de España y de América (PRESEEA) corpus. We implement analytical innovations by exploring transitivity and the lexical effect of the verb, which we analyze by testing infinitives and subject pronoun + verb collocations, respectively, as standalone, random-effect factors. Our results reveal the highest pronominal rate (28%) found in a mainland Spanish-speaking community. Additionally, we uncover that pronominal rates increase with age, a finding which appears to have cognitive implications. The internal conditioning contributes to pronombrista studies by showing the effects of discourse type and transitivity. Narratives and opinion statements favor overt subjects, but statements indicating routine activities favor null subjects. Whereas unergative verbs promote overt subjects, reflexive verbs favor null subjects. The lexical effect of the verb reveals opposing tendencies between verbs in the same category as well as within different collocations of the same verb, providing more definitive answers than the semantically guided approaches used for the last four decades and showing that verb groupings do not constitute functional categories with regard to SPE. Overall, this study contributes to expand our baseline knowledge of SPE in mainland Latin American communities and opens interesting research avenues.

Narrow reading, vocabulary load and collocations in context: Exploring lexical repetition in concordances from a pedagogical perspective

Narrow reading has the potential to reduce vocabulary load and to provide rich opportunities for developing collocation knowledge, but these benefits rely on narrow reading increasing lexical repetition within a text. Hence, interest in narrow reading has been limited by the relatively small lexical effect of narrowing reading by topic (Nation, 2013). Nevertheless, research in data-driven learning and teaching and language corpora has reported positively on learners using concordances in a manner comparable to narrow reading. However, the potential for concordances to provide an increased lexical-repetition effect has not been assessed. This study bridges this gap by exploring the degree of lexical repetition available in concordances and identifies corpus composition as a key predictor of lexical repetition. The study uses standardised type-token ratio (sTTR) to analyse concordances extracted from corpora at three different levels of homogeneity/heterogeneity. The results show large, reliable variations in lexical repetition resulting from variation in corpus homogeneity/heterogeneity, and so identifies concordance-based narrow reading as a possible means of overcoming the limitations of traditional narrow reading by topic. The results are discussed with reference to pedagogical implications for language learners, teachers, and researchers.

The Interaction of Lexical Characteristics and Speech Production in Parkinson's Disease

Purpose This study sought to investigate the interaction of speech movement execution with higher order lexical parameters. The authors examined how lexical characteristics affect speech output in individuals with Parkinson's disease (PD) and healthy control (HC) speakers. Method Twenty speakers with PD and 12 healthy speakers read sentences with target words that varied in word frequency and neighborhood density. The formant transitions (F2 slopes) of the diphthongs in the target words were compared across lexical categories between PD and HC groups. Results Both groups of speakers produced steeper F2 slopes for the diphthongs in less frequent words and words from sparse neighborhoods. The magnitude of the increase in F2 slopes was significantly less in the PD than HC group. The lexical effect on the F2 slope differed among the diphthongs and between the 2 groups. Conclusions PD and healthy speakers varied their acoustic output on the basis of word frequency and neighborhood density. F2 slope variations can be traced to higher level lexical differences. This lexical effect on articulation, however, appears to be constrained by PD.

Gestural overlap across word boundaries: Evidence from English and Mandarin speakers

This article examines how three factors determine the surface forms of English stop-stop coarticulation across word boundaries in both native and nonnative speech: place of articulation, frequency, and speech rate. The release percentage and closure duration ratio produced by English (L1) and Mandarin (L2) speakers were measured. The results showed that a place order effect was only partially supported in L1 speech but not shown at all in L2 speech. The results also confirmed a gradient lexical effect, finding a significant correlation between self-rated frequency and overlap. In addition, the results showed that increased speech rate did not induce increased overlap, given that speakers from both groups had either more or less overlap at the fast speech rate than at the slow rate.
