Article
This paper addresses the relation between syllable structure and inter-segmental temporal coordination. The data examined are Electromagnetic Articulometry recordings from six speakers of Central Peninsular Spanish (henceforth, Spanish), producing words beginning with the clusters /pl, bl, kl, gl, pɾ, kɾ, tɾ/ as well as corresponding unclustered so...

This paper employs ultrasound and nasometric instruments in a variable-rate reading task to examine regressive nasalization in Québec French. We measure tongue height according to nasality of context, as well as percent nasality (via an energy-based ratio formula) and vowel duration. Results show high degrees of nasalization for high vowels and cer...

We examined gestural coordination in C1C2 (C1 stop, C2 lateral or tap) word initial clusters using articulatory (electromagnetic articulometry) and acoustic data from six speakers of Standard Peninsular Spanish. We report on patterns of voice onset time (VOT), gestural plateau duration of C1, C2, and their overlap. For VOT, as expected, place of ar...

Although recent research has shed some light on relative timing in laryngeal and oral articulatory gestures, little is known about articulatory patterns of second language (L2) users along the trajectory from novice to expert. We report results of an electromagnetic articulographic (EMA) investigation of two native English speakers' L2 Spanish-lang...
Conference Paper
Full-text available
We examine ultrasound and nasometric data in a variable rate task to quantify the influence of vowel quality, duration, and intraoral gestures on regres-sive nasalization in Montreal French. Acoustic results suggest that, while on average high and mid vowels are heavily nasalized in this context, only certain high vowels remain significantly nasal...
Presentation
Full-text available
Gestures, coordinated speech movements, are units of speech motor control. As a consequence, they carry information related to duration, relative timing, range of motion, target accuracy and speed (Gafos & Lieshout, 2020). Studies on anticipatory coarticulation have proved the lack of planned speech in young children (Barbier, G. t al, 2020), even...
Article
We examined the Spanish productions of four syllable-level timing parameters by bilingual English-and Spanish-speaking children with normal hearing (NH group, henceforth) and bilingual English-and Spanish-speaking children with cochlear implants (CI group, henceforth) during the stages of phonological development. The four temporal variables relate...

This study compares two markers of Specific Language Impairment in Spanish children aged 5 to 7. The markers examined are sentence repetition and pseudoword repetition, which are the two main tasks outlined in the research to identify this disorder. Both contemplate memory deficits as the source of this disorder. We review the ways in which these t...
Article
Full-text available
Previous research has shown vast differences in the way that non-native and native speakers perceive foreign accents, whether authentically produced by second language (L2, henceforth) speakers or imitated by native (L1, henceforth) speakers of the language in question. Such differences in the way speakers from different languages perceive foreign...
Article
Full-text available
A stochastic analysis using aerodynamic and temporal variables is presented to explain tap/trill variation in Spanish codas. Simultaneous intraoral pressure (Po), translingual flow (F) and acoustic signals were obtained for two native speakers of Peninsular Spanish performing a rate-controlled reiterative task. Data were analyzed using linear mixed...
Article
Full-text available
A series of hypotheses are addressed vis-à-vis the effects of syllable complexity and voicing on consonant duration and VOT (voice onset time) in a subset of Spanish clusters. Electropalatographic (EPG) and acoustic signals were obtained for native-speakers of Standard Peninsular Spanish producing clusters within and across word boundaries. The res...
Article
A hypothesis is proposed which claims that vowel prosthesis before word-initial [sC] clusters by L1 Spanish learners of English is a perception-based repair phenomenon conditioned by L1 biases for native patterns of intergestural timing in complex onsets. Data from a series of off-line perception tests involving fifty L1 Spanish-speaking children c...
Article
Full-text available
Results are reported for a series of hypotheses related to overlap patterns in Spanish clusters. In line with past findings for French and other languages, significant interplateau intervals exist between the articulatory plateaus in all C1C2 clusters. In contrast with French, however, it was found that the voicing specification of the C1 affects t...

The theoretical base of my study with Spanish speaking children aged from four to seven years old with cochlear implants explores the development of speech timing by children who use cochlear implants and children with normal hearing. Previous research has shown that the timing of speech gestures varies as a function of language (Kochetov, Pouplier & Son, 2007), develops over the course of normal phonological acquisition (Bosch & Sebastian-Galles, 1997; Lowenstein & Nittrouer, 2008, among others), and may affect the production of non-native patterns (Zsiga, 2003; Tobin, Gibson, Sotiropoulou & Gafos, 2019). However, there is a general lack of research dealing with the interaction of speech timing, fine motor control and phonological awareness in the literature.
Project
Many studies addressing emotion detection in speech use samples of ‘acted’ emotions performed by actors, which may sound similar to ‘authentic’ emotions, but lack the physiological impetus responsible for the acoustic cues that materialize during the expression of authentic emotion. Therefore, for the project, we used speech samples collected from a clinical setting, with the participant's informed consent. The aim is to obtain acoustic knowledge on how speech dimensions vary when speaker's emotion changes from neutral to a certain emotional state (happiness or sadness).
