Audiodescripció i recepció : efecte de la velocitat de narració, l\'entonació i l\'explicitació en la comprensió fílmica

This PhD thesis is an experimental reception study on audio description (AD) for the blind and the visually impaired in which we test the effect of AD narration speed, intonation and explicitation on film comprehension and, secondarily, on enjoyment. First of all, we review and classify the main literature on AD up to 2012, with a special emphasis on Catalonia and Spain. After that, we present the theoretical frame chosen (Branigan 1992) and its concept of narrative schema, which allows us to define film comprehension and to have a theoretical basis to tackle some methodological aspects related to the experiment. Next, we explain the methodological aspects of the research, such as the selection, the narratological analysis and the manipulation of the corpus; the creation of the measurement scale of comprehension; the creation of the experimental groups (blind and visually impaired people) and the control group (sighted people); and other ethical and data processing issues. On the third place, we present a quantitative analysis of the results on comprehension and a qualitative analysis on the enjoyment for the different groups and values of the AD parameters which were manipulated. Finally, we highlight the tendencies observed in the analysis and we provide some recommendations which can be applied both to the professional and the teaching practice of AD and which complement the vagueness of most AD standards.
