Pitch accent alignment in romance: primary and secondary associations with metrical structure.

The article describes the contrastive possibilities of alignment of high accents in three Romance varieties, namely, Central Catalan, Neapolitan Italian, and Pisa Italian. The Romance languages analyzed in this article provide crucial evidence that small differences in alignment in rising accents should be encoded phonologically. To account for such facts within the AM model, the article develops the notion of “phonological anchoring” as an extension of the concept of secondary association originally proposed by Pierrehumbert and Beckman (1988), and later adopted by Grice (1995), Grice, Ladd, and Arvaniti (2000), and others to explain the behavior of edge tones. The Romance data represent evidence that not only peripheral edge tones seek secondary associations. We claim that the phonological representation of

Prosodic manifestations of the Effort Code in Catalan, Italian and Spanish contrastive focus

This paper investigates the relevance of three prosodic parameters (alignment, duration and scaling) in the conveyance of contrastive focus in Catalan, Italian and Spanish. In particular, we seek to determine how the Effort Code is instantiated in the expression of contrastive focus in both production and perception. According to the Effort Code, putting more effort into speech production will lead to greater articulatory precision (de Jong 1995, Gussenhoven 2004) and this is related to the expression of focus in the sense that wider pitch excursions will be used to signal meanings that are relevant from an informational point of view. A dual production and perception experiment based on an identification task was conducted. Results for the production part show that contrastive focus accents have earlier peaks for all three languages but f0 peaks are systematically lower only in Italian. Syllables bearing the contrastive focus accents are also longer in the three languages. Regarding the results for the perception part, converging evidence is found not only for an active perceptual use of the three prosodic parameters present in production but also for language-specific preferences for particular prosodic parameters.

Numerical instabilities and three-dimensional electromagnetic articulography

The AG500 electromagnetic articulograph is widely used to reconstruct the movements of the articulatory organs. Nevertheless, some anomalies in its performance have been observed. It is well known that accuracy of the device is affected by electromagnetic interference and possible hardware failures or damage to the sensors. In this study, after eliminating any hardware or electromagnetic source of disturbance, a set of trials was carried out. The tests prove that anomalies in sensor position tracking are systematic in certain regions within the recording volume and, more importantly, show a specific pattern that can be clearly attributed to a wrong convergence of the calculation method.

Assimilation of L2 vowels to L1 phonemes governs L2 learning in adulthood: a behavioral and ERP study

According to the Perceptual Assimilation Model (PAM), articulatory similarity/dissimilarity between sounds of the second language (L2) and the native language (L1) governs L2 learnability in adulthood and predicts L2 sound perception by naïve listeners. We performed behavioral and neurophysiological experiments on two groups of university students at the first and fifth years of the English language curriculum and on a group of naïve listeners. Categorization and discrimination tests, as well as the mismatch negativity (MMN) brain response to L2 sound changes, showed that the discriminatory capabilities of the students did not significantly differ from those of the naïve subjects. In line with the PAM model, we extend the findings of previous behavioral studies showing that, at the neural level, classroom instruction in adulthood relies on assimilation of L2 vowels to L1 phoneme categories and does not trigger improvement in L2 phonetic discrimination. Implications for L2 classroom teaching practices are discussed.

The relevance of prosody and context to the interplay between intensity and politeness. An exploratory study on Italian

Abstract The linguistic feature of intensity, lying “at the heart of social and emotional expression” (Labov 1984: 43), is significantly intertwined with politeness. In relation with intensity (that is, both upgrading and downgrading), the role of context and prosody in modifying and expressing politeness is discussed here in a pragmatic perspective. The complex interplay between intensity, politeness and prosody is explored with reference to several examples related to Italian, showing both the crucial role of prosody in conveying politeness and intensity and the relevance of global and local context parameters. In the paper, prosody acts as a pivot, with regard to which we discuss the status of the other components. In particular, it is shown to play an important role in constructing politeness and its variations of intensity under the influence of contextual parameter. Prosody may perform a primary distinctive function, or may jointly with other convergent or divergent cues express the meaning and politeness intended by the speaker. However, the overall effect of a speech act in terms of politeness is shown to be due to the variegated intertwinement between context, intensity and prosody, which is at play with or without other linguistic forms of politeness and accounts for the lack of a one-to-one correspondence between politeness and single utterance features.

Assessing the position tracking reliability of Carstens’ AG500 and AG501 electromagnetic articulographs during constrained movements and speech tasks

Abstract The goal of this study is to qualitatively and quantitatively assess the reliability of the AG501 Electromagnetic Articulograph (Carstens Medizinelektronik GmbH) and to compare it with the previous model, the AG500, which is still widely used in the 3D recording of articulatory movements. To explore and test the spatial accuracy of the articulographs in various areas of the recording volume, controlled sensor positions at fixed locations and along circular trajectories as well as movements of articulators of the speakers vocal tract during speech production tasks were tracked and analysed. It is well known that the AG500 trajectories are affected by perturbations which: (i) depend on the position of the sensors/subject within the recording volume and (ii) randomly occur along repetitions of the same sound in the same recording area. This study has shown that these issues do not affect the newer AG501, which not only performs according to the manufacturers claim of 0.3u202fmm dynamical accuracy within a 20-cm-wide spherical region inside the recording volume, but also performs well outside. Furthermore, while the AG500 shows perturbed trajectories in some instances, the AG501 consistently shows accurate results in reproducing the displacements of consonantal and vocalic gestures for the tested speech tasks. Our findings reveal that the AG501 is more stable and significantly more accurate than the previous model, the AG500, which, in turn, performs reasonably well only in specific limited conditions.
