Perfil de fluência da fala infantil capixaba: comparação com a variedade mineira e diferentes métodos de coleta

Abstract

Fluency is understood as the continuous and smooth flow of speech production and can be determined from aspects such as the rate of speech and typology of disfluencies. The objective of this thesis is to compare the child speech fluency in the Minas Gerais and Capixaba varieties of Brazilian Portuguese, and to verify the interference of different methods of collection in speech fluency. The study included 201 children aged 6 to 11 years, who produced a total of 410 speech samples collected through three distinct experiments. In the first experiment, the collection was performed with a speech task with static figures. In the second experiment, the different speech tasks were collected with static figures and semi-spontaneous speech. In the third experiment, the gathering of data was performed with different speech tasks (static figures, sequence story, and semi-spontaneous speech) and with the different orders of the meetings (first, second and third meeting). In the first experiment, the speech rate was similar between Minas Gerais and Capixaba varieties, while speech discontinuity, typical disfluency of hesitation, and atypical disfluencies of prolongation, pause, and intrusion of sound or segment were higher in the Minas Gerais variety and the typical disfluency of revision was higher in the Capixaba variety. In the second experiment, the results showed similarity in the rate of speech, speech discontinuity, and typical and atypical disfluency, among the different methods of speech collection through static figures and semi-spontaneous speech. In the third experiment, when we analyzed the different tasks in speech gathering in isolation, there was a significant statistical difference between the speech gathering methods that showed lower speech rate and lower speech discontinuity in the speech task with a static figure. On the other hand, the semi-spontaneous speech was shown to have a higher rate of speech (word per minute), greater speech discontinuity, hesitation, and interjection. When analyzing in isolation the different orders of the meetings for speech collection, we found that the order of the meetings alone does not interfere with the speech fluency variables. Also in the third meeting, when analyzing the different speech tasks associated with the different orders of the meetings, we verified that the rate of speech remained similar between the different methods. However, the first meeting proved to be more prone to increasing speech discontinuity in typical and atypical disfluencies. On the contrary, the third meeting was more favorable for fluency with a reduction of typical and atypical disfluencies. In general, it is understood that there is a regional difference between the Minas Gerais and Capixaba varieties and that the different gathering methods interfere in the child speech fluency.
