Resumo
O presente trabalho de mestrado refere-se a um estudo acústico de pronúncia, que tem como principal objetivo verificar e analisar, por meio de registros de fala de professores brasileiros, de alunos de língua inglesa em nível intermediário e avançado, e de falantes nativos americanos, a maneira como esses indivíduos realizam os pares mínimos vocálicos /i/ e /I/, /E/ e /Q/. O primeiro critério de análise foi a aplicação de um questionário aos professores e alunos participantes; por meio dele, foi possível traçar as competências dos docentes e definir a atuação dos discentes como alunos de inglês; ademais, foi possível encaixá-los nos níveis de proficiência determinados pela escola onde os dados foram coletados. Com relação aos critérios acústicos, foram utilizados os seguintes parâmetros: o valor das freqüências de F1 e F2 das vogais produzidas pelos sujeitos participantes, sendo possível verificar o movimento de avanço / recuo e levantamento / abaixamento do corpo da língua durante a articulação dos segmentos; a diferença formântica entre F1 e F2, parâmetro que melhor define o grau de posterioridade de um som vocálico; e, por fim, a duração dos segmentos, parâmetro acústico essencial para a distinção entre as vogais analisadas. Sobre a metodologia de pesquisa, foram gravados 28 sujeitos: dois americanos nativos, dois professores brasileiros de inglês e 24 alunos brasileiros de uma escola de idiomas localizada em São José do Rio Preto (SP). Foi pedido para que cada indivíduo repetisse os pares de palavras cheap / chip e beg / bag três vezes (nesses vocábulos, realizam-se as vogais /i/ e /I/, /E/ e /Q/). Por meio das gravações, foi possível realizar a medição da freqüência dos formantes F1 e F2 das vogais produzidas por eles, bem como a medição da duração de cada som vocálico. A repetição por três vezes dos pares mínimos...
This master paper is an acoustic study of pronunciation, whose main goal is verify and analyze, through speech data of Brazilian teachers, intermediate and advanced students of English, and American native speakers, the way these people produce the vocalic minimal pairs /i/ and /I/, /E/ and /Q/. The first criterion of analysis was related to a questionnaire answered by the teachers and the students; this questionnaire allowed the researcher to define the teachers’ competences and the learners’ behavior as English students; besides, it was possible to fit them into the levels of proficiency determined by the school where the data was collected. Regarding the acoustic criteria, the following fundamental parameters were taken into consideration: F1 and F2 frequency values of vowels produced by the participants, in which it was possible to verify the tongue movements, associated with advancement and height, during the segmental articulation; the formant differences between F1 and F2, which better defines the posterior position of a vowel; and, finally, the segmental duration, which is an important acoustic parameter to distinguish the analyzed vowels. Concerning the research methodology, 28 people were recorded: two native Americans, two Brazilian English teachers and 24 Brazilian students from a language school located in São José do Rio Preto (SP). Each person had to repeat the pair of words cheap / chip and beg / bag for three times (in such words, the vowels /i/ and /I/, /E/ and /Q/ are expected to occur). With the recordings, it was possible to measure F1 and F2 frequencies of the vowels produced by the participants, as well as the duration of each vocalic sound. In the analyses, the absolute values of the formants and duration were not taken into consideration but an arithmetic average of the values from the three utterances of each case. It was concluded that the Brazilian... (Complete abstract click electronic access below)
