Proposta de um simulador de treinamento para a avaliação perceptivo-auditiva da voz

Abstract

The auditory-perceptual assessment (APA) is the main vocal assessment procedure used by the speech-language pathologist capable of assessing whether there is presence, degree and predominance of voice quality deviation (QoL). As it is based on the clinician's perception, APA is considered a subjective analysis of variable reliability, as it can be influenced by several factors, including training. With technological advances, traditional teaching strategies are gradually being complemented by interactive teaching approaches. In this context, the use of resources that help in the students' learning process, such as training simulators (TS), allow controlled experiences of different situations in the professional scope (common and atypical). The aim of this study is to propose a ST for the APA. To achieve the proposed objective, the study was divided into 3 stages. In the first stage, a questionnaire was developed and applied remotely with professors who teach or have already taught subjects that involve performing auditory-perceptive training (APT). In the second stage, based on the previous stage and on the literature in the area, the APT structure, the metrics and the decision model for user evaluation were defined. Finally, the development of the ST and the simulation of profiles were carried out. The developed ST, Listening to Voices, is formed by 4 training stages with increasing difficulty level. These stages have specific objectives and are subdivided into phases. Ouvindo Vozes has a decision model formed by a system based on rules, which compares the evaluation performed by the user with the evaluation of the experts. Users are evaluated according to the performance index (accuracy, sensitivity, specificity and internal agreement) corresponding to their level of experience. The more experienced the higher the performance index to be achieved. During the course of their training, the user may have their performance index decremented according to their performance and the rules implemented in the decision model. Despite the variations in the different types of APT, it was possible to establish a structure and metrics for the APT of Ouvindo Vozes. After the profile simulations, it was found that the decision model was able to verify and direct the user's progress. pedagogical approach in helping teachers and students to carry out the APT.
