Comparação entre medidas acústicas de vogais em provas de repetição e conversa espontânea

The aim of this study is to compare acoustic measures (frequency, duration and intensity) of the vowels /i, a, u/ in repetition and spontaneous tasks. Recordings of words produced by ten children with typical language development in both controlled and spontaneous tasks were selected from a database. The vowels were selected and edited into individual files in the software PRAAT. Acoustic measures related to formant frequency (F1 and F2), intensity and duration of vowels in both contexts were extracted. The values obtained were compared by means of T Tests. In general, the acoustic analysis showed no differences between the two contexts of speech production. The few differences found can be explained by the presence of focus and/or hesitation phenomena during the speech productions. It is possible to use data from spontaneous context to analyze the vowels acoustically, provided that both the phonetic context of the vowel occurrence and the syllable stress of the vocalic segment are considered.

Vogais mediais pretônicas no noroeste paulista: o papel das variáveis sociais no alçamento vocálico

In this paper, we investigate to which extent social variables act on the medial vowel raising phenomenon in the Portuguese variety spoken in São José do Rio Preto, a city in the countryside of São Paulo State. Based on the theoretical-methodological model of Sociolinguistics Variacionist, we analyse speech samples from this city, the Iboruna database. The results show that the vowel raising applies: (i) for both men and women; (ii) in all age groups and, (iii) in all levels of formal education. Taking into consideration the results of analysis of social and linguistic variables selected by the program GoldVarb, we find evidences that vowel raising phenomenon is not sensitive to social pressures in the speech community studied, which allows us to affirm that it is not a phenomenon socially stigmatized and the variation in its implementation is more strongly subject to linguistic variables.

Estudo acústico das vogais do português brasileiro

In the area of Phonetics, current studies are mainly geared toward acoustic analysis of the speech. The technology of personal computers and available software made these analyses easier to be carried out. The following work used the software called PRAAT. Besides showing how it helps the researcher, the aim of this work is to bring new data for future consultation in this field, allowing comparisons and discussions about this subject. At FONAC, a place where a Project of Departmental Traineeship is run, coordinated by Prof. Dr. Luiz Carlos Cagliari and aimed at training on Acoustic Phonetics for undergraduates and graduates, there is a good quality recording, in which a speaker of the paulista dialect reads an excerpt of Michael Ende and Annegert Fuchshuber’s book named ‘The Dream-eater’ twice. The data obtained through it were analyzed directly or by statistic procedures. Tables and charts, created from these data, helped to visualize the similarities and differences between the vowels allowing an easier comprehension of the articulatory phenomenon. With the formants, specifically, prototypical values for the vowels of Portuguese and the dialect in study were obtained

A redução de vogais no português: estudo de uma amostra do PE em comparação com o PB

This study aims to verify the reduction phenomenon and/or disappearance of vowels, especially unstressed vowels in PE compared to the PB, obtained by analysis of the recording of an oral reading sample of the Mar Português poem, by Fernando Pessoa, made by informants of the two variants. The noticeable difference in pronunciation of the informants, with any possibility of reaching up to no understanding of European pronunciation by Brazilian speakers motivated the development of an experiment that allowed us to compare the duration of vowels produced in the two variants. By isolating and measuring the vowels at Praat audio analysis program, this study was to confirm the reduction and, in extreme cases, the disappearance of unstressed vowels in PE, a phenomenon described in Mateus and D'Andrade (2000)

As vogais postônicas do século XIII: um olhar sobre a escrita da época

This work aims to obtain a phonological description of unstressed word-final vowels of Medieval Portuguese (MP). The corpus of this research is comprised of Alfonso X’s Cantigas de Santa Maria, composed on the second half of the 13th century. This work maps all the graphemes that represent, in the corpus considered, the unstressed word-final vowels. From the analyses of writing and rhymes in Alfonso X’s Cantigas de Santa Maria, it was possible obtain some important information about the realization of the unstressed wordfinal vowels in MP.

O uso de drogas anticoagulantes e antiplaquetárias orais em pacientes cirúrgicos ambulatoriais: revisão de literatura

The oral anticoagulants (AOC) and platelet antiagregants are drugs used for the prevention of thromboembolic phenomena, such as pulmonary embolism in patients with atrial fribrilation heart valves, thrombosis and pulmonary embolism. For patients who are undergoing surgical procedures-dentistry were asked to discontinue the use of anticoagulants until the value of the INR remained = 2.0, that in order to avoid trans and hemorrhages in the postoperative period. However, the AOC can cause the formation of a clot, leading to obstruction of blood pathways. Thus, it became doubtful the medicine for surgery, in which local hemostatic measures would be sufficient to promote hemostasis. Thus, the objective of the review was to evaluate the risk of bleeding in patients AOC users that are subjected to surgical procedures, through a bibliographical survey carried out in relevant clinical studies published between 1990 and 2012, by the MedlinePubMed data. In this review of literature was concluded that the benefit of thromboembolism prevention overcomes the risk hemorrhage, therefore, it is recommended to keep the dose of anticoagulant therapy unchanged for patients undergoing oral surgery and implant dentistry, using appropriate INR levels with the assistance of local hemostatic. In addition, a refined surgical technique should be performed in these patients. With respect to the most invasive oral surgery, with a risk of bleeding, treatment may be necessary in conjunction with the medical staff.

Biofilmes orais como um possível fator de risco ao câncer bucal: revisão da literatura

Introduction: much studies regarding risk factors associated with oral cancer. Factors such as smoking and alcohol and solar radiation are well established, but others, such as bacterial influence in the development or progression of a tumor still remain unexplained. Interest in the possible relationship between bacteria and different stages of cancer development has increased since the classification of H. pylori by the WHO as a definite carcinogen. Subsequently, links between infection and the onset of cancer in various sites in the body were discovered. Review of literature: this literature review attempts to show the influence of poor oral hygiene, with consequent bacterial accumulation as a possible important risk factor for the initiation and development of mouth cancer, and correlate the possible mechanisms by which bacteria can initiate or promote carcinogenesis. Conclusion: there is much evidence that bacteria in the oral cavity and periodontopathic are present in tumor tissue, however, still can not affirm that these bacteria initiate or promote carcinogenesis.
