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, p¿, k¿, t¿/ as well as corresponding unclustered sonorant-initial words in three vowel contexts /a, e, o/. In our results, we find evidence for a global organization of the segments involved in these combinations. This is reflected in a number of ways: shortening of the prevocalic sonorant in the cluster-initial case compared to the unclustered case, reorganization of the relative timing of the internal CV subsequence (in a CCV) in the obstruent-lateral context, early vowel initiation, and a strong compensatory relation between the duration of the obstruent-to-lateral transition and the duration of the lateral. In other words, we find that the global organization presiding over the segments partaking in these tautosyllabic CCVs is pleiotropic, that is, simultaneously expressed over a set of different phonetic parameters rather than via a privileged metric such as c-center stability or any other such given single measure (employed in prior works).

Objetivo El objetivo de este trabajo es comparar 2 marcadores del trastorno específico del lenguaje en niños españoles de 5 a 7 años. Estos marcadores son la repetición de oraciones y la repetición de pseudopalabras, que son los utilizados para esta función en la investigación sobre este trastorno. Los 2 remiten a déficits de memoria como origen de este trastorno. Se revisan las formas en que estas tareas han sido utilizadas en el marcaje del trastorno específico del lenguaje. Participantes Se han aplicado estas tareas a 3 grupos de niños de 5 a 7 años; uno constituido por niños con trastorno específico del lenguaje, otro por niños con trastorno de habla y articulación y otro con niños con desarrollo típico. Resultados Los análisis discriminantes y la curva ROC ponen de manifiesto que es la repetición de oraciones la que tiene una mayor sensibilidad y especificidad para distinguir a los niños con trastorno específico del lenguaje de los niños con desarrollo típico, pero muestra una sensibilidad discreta en la diferenciación de los niños con desarrollo típico de los que tienen trastorno de habla y articulación. Ninguna de las tareas logra diferenciar con una precisión aceptable a los niños con trastorno específico del lenguaje de los que tienen trastorno de habla y articulación. Discusión y conclusiones Se explican las razones de la distinta potencia marcadora de ambas tareas para identificar a los niños con trastorno específico del lenguaje, trastorno de habla y articulac

This methodological study presents the results of an initiative to create a new data management and prompting system which can be interfaced with acoustic data for research in acoustic phonetics. The objectives of this initiative were to provide an economical way to record, organize and manipulate acoustic data and to construct a system which allows the use of external recording equipment for production experiments. For the project, a program was designed with a built-in visual prompting system which simultaneously synchronizes the text in accordance with defined temporal regions in the long file for easy extraction for use in perception experiments. Results of external assessment were considerably positive due to the user-friendly platform which does not require scripting, meaning the organization and manipulation of data files is less time-consuming and more efficient

This article discusses the topic of stress in Spanish and its relationship to a higher metrical category called the foot. A general typology couched in the theoretic architecture of Optimality Theory is provided. I argue and illustrate that all stress patterns in Spanish non-verbs can be justified by a ranking schema of constraints which first govern the shape of metrical feet, and later determine the alignment of these feet to the syllable

This volume explores several recurring topics in Romance phonetics and phonology, with a special focus on the segment, syllable, word, and phrase levels of analysis. An international team of experts and junior researchers present research that ranges from the low-level mechanical processes involved in speech production and perception to high-level representation and computation, based on data from across the Romance language family, including from varieties that are less widely studied. The book is divided into five parts. In the first, chapters present acoustic studies, examining topics such as Italian anaphonesis and voiceless fricative sibilants in Galician, while chapters in part two turn to articulatory studies of features including three-consonant onsets in Romanian and rhotic variation in Tuscan Italian. The focus of the third part is perception, and includes studies of perceived phrasing in French and perceptual cues for individual voice quality, while part four examines phonological issues such as Galician mid-vowel reduction and sibilant voicing in Spanish. Chapters in the final part of the volume look at the effects of production and perception on issues in language acquisition. The book draws on a range of experimental and methodological approaches and will be of interest not only to scholars of Romance linguistics but also to all those working in phonetics and phonology from graduate level upwards
