Objectives, competences and learning Outcomes

The Audio and Visual Voice Perception course aims to equip students with skills to identify and discriminate, auditory and visually, pathological and non-pathological voices. Students will identify, describe and solve situations of patients with or without vocal disorders through visual-perceptual and audio data, integrating previous anatomical-physiological knowledge. They should be able to explore and interpret results of the auditory and visual analysis of voice, using software and specific tests for evaluating these parameters.

Teaching and Learning Strategies

The methods of teaching this course include a component directed toward the exhibition particularly the first group of content, and include an experimental component predominant, especially applicable to the second and third groups of content.

Type of assessment

Assessment

The assessment includes a written exam covering the theoretical foundations of this course, with a weight of 35% in the final standings, and includes a set of challenges or experimental work and review the implementation of which contributes the remaining 65% for the final classification.
