“…Yet, the majority of articulatory work done so far has focused on a handful of languages, most of which are native to Europe. Thus, among articulatory phonetic studies published in major journals between 2000 and 2019, more than one third focus on English, and more than two thirds focus on Indo-European languages native to Europe (with the bulk being major Germanic and Romance languages; Kochetov 2020). Given this linguistic bias, it remains to be seen whether empirical findings and theoretical generalizations obtained based on major European languages can extend to a wider range of sound pattern types.…”

This paper investigates the production of dental and retroflex stops, fricatives, nasals, and laterals in the Dravidian language Kannada. This is done using articulatory contours extracted from an extensive midsagittal MRI corpus of two female Kannada speakers’ static vocal tract postures intended to capture key aspects of phonemic articulations. Articulatory modelling was used to determine a set of components responsible for the implementation of place and manner contrasts (/t̪ s̪ n̪ l̪/ vs. /ʈ ʂ ɳ ɭ/). These components included both lingual and non-lingual articulatory parameters. Constriction location and length were also determined based on articulatory contours. The results showed that the two speakers produced non-fricative retroflexes with a retracted tongue tip making a constriction behind the alveolar ridge and a characteristic convex tongue shape, yet without a retraction of the posterior portion of the tongue. Apart from the lingual parameters, place differences were also manifested by the vertical position of the larynx (lower for retroflexes). The realisation of the place contrast in sibilant fricatives was different, as /ʂ/ appeared to be produced by both speakers with a laminal alveolopalatal constriction. Manner differences were captured by various non-lingual parameters, yet being also manifested in constriction locations (more anterior for stops). These findings are discussed in the context of previous descriptive and articulatory accounts of dental-retroflex contrasts.

“…Doing so could have contributed to a more thorough understanding and analysis of the topic under study. Considering that aerodynamic experiments have reported small(er) sample sizes (Kochetov 2020), the current study is a significant contribution to the literature on syllable structure, Spanish phonology, and articulatory phonetics.…”

The Role of (Re)Syllabification on Coarticulatory Nasalization: Aerodynamic Evidence from Spanish

Tautosyllabic segment sequences exhibit greater gestural overlap than heterosyllabic ones. In Spanish, it is presumed that word-final consonants followed by a word-initial vowel undergo resyllabification, and generative phonology assumes that canonical CV.CV# and derived CV.C#V onsets are structurally identical. However, recent studies have not found evidence of this structural similarity in the acoustics. The current goal is to investigate anticipatory and carryover vowel nasalization patterns in tautosyllabic, heterosyllabic, and resyllabified segment sequences in Spanish. Nine native speakers of Peninsular Spanish participated in a read-aloud task. Nasal airflow data were extracted using pressure transducers connected to a vented mask. Each participant produced forty target tokens with CV.CV# (control), CVN# (tautosyllabic), CV.NV# (heterosyllabic), and CV.N#V (resyllabification) structures. Forty timepoints were obtained from each vowel to observe airflow dynamics, resulting in a total of 25,200 datapoints analyzed. Regarding anticipatory vowel nasalization, the CVN# sequence shows an earlier onset of nasalization, while CV.NV# and CV.N#V sequences illustrate parallel patterns among them. Carryover vowel nasalization exhibited greater nasal spreading than anticipatory nasalization, and vowels in CV.NV# and CV.N#V structures showed symmetrical nasalization patterns. These results imply that syllable structure affects nasal gestural overlap and that aerodynamic characteristics of vowels are unaffected across word boundaries.

“…This could be the result of the amount of data we are contemplating. Although 16 participants comprise a sound sample for an articulatory study (Kochetov 2020), trying to ascertain or corroborate the correlation between variables in such a diverse, non-uniform group with considerable individual variation is not an easy task. This is not a novel claim, as previous literature on HL phonetics and phonology has warned about the 'risks' of and considerations for undertaking HL research.…”

An Airflow Analysis of Spanish and English Anticipatory Vowel Nasalization among Heritage Bilinguals

Gestural timing overlap between a vowel and subsequent nasal consonant results in the vowel being articulatorily nasalized. Research has shown that such degree of coarticulation varies cross-linguistically (e.g., English exhibits a greater gestural timing overlap than Spanish). This phenomenon has mainly been investigated in monolingual samples, and with only a small number of studies focusing on second and heritage language gestural timing patterns of nasality; the role of bilingualism in this respect is thus an open question, which is the focus of the current study. Sixteen second-generation US-born heritage bilinguals participated in this experiment. Their degree of bilingualism was assessed via the Bilingual Language Profile. They completed two separate read-aloud tasks: one in Spanish (heritage language) and one in English (second language). Simultaneous oral and nasal airflow were collected via pressure transducers from words that included phonetically oral and nasalized vowels. Results indicate that heritage bilinguals increment the degree of vocalic nasalization from Spanish to English. Nevertheless, their degree of bilingualism did not yield statistical significance in phonetic performance. The current study is the first one implementing aerodynamic methods with a heritage bilingual population and presents data for the possibility to possess two segment-to-segment timing strategies in heritage grammars.
