| local.description.resumo | This study aimed to analyze the effects of the expression of emotions on voice, speech and fluency of an aviator in a real aeronautical accident case. For that, data from the communication between the pilot and the control tower stored in the CVR (Cockpit Voice Recorder) of the aircraft in the day of the accident were extracted and compared with their speech samples of the previous days. It should be noted that the aviator had been flying in a day of intense rain when he reported difficulty in landing due to poor visibility conditions. For the analysis, the script for evaluation of the acoustic parameters of the emotions of Scherer was followed. This analysis was also based on the conception that the emotional state influences the speaker, causing variations resulting from the physiological responses elicited in the individual by the emotions. These variations cause changes in breathing, phonation and articulation. It is emphasized that emotions are produced from an automatic cognitive assessment of the individual on external and internal events considered relevant to their interests and needs. They are also characterized by a high degree of synchronization of the organism's subsystems. It was verified that, at the date of the accident, the pilot presented variations of voice, speech and fluency such as increased articulation rate, acute pitch compared to the prior days to the accident and to the normality pattern for Brazilian speakers of male gender, incoordination of breathing, tense vocal quality, breathless speech and tremulous voice. Considering studies on acoustic and clinical parameters to evaluate the expression of emotions, it is possible to infer that the pilot presented traces of apprehension / anxiety and anxiety varying to the fear in audio of the day of the accident, especially in the instant immediately before the impact. | |
