Article Synopsis
- The study aimed to evaluate how auditory training with synthesized voices affects the consistency among raters in analyzing voice qualities like roughness and breathiness.
- The experimental design involved twenty Speech-Language Pathology students who completed four training sessions, incorporating pre-training, training with synthesized sounds, and post-training evaluations of natural voices.
- Results showed significant improvements in both intra-rater agreement (consistency of the same rater) and inter-rater agreement (consistency among different raters) for ratings of roughness and breathiness after the training.
Purpose: To analyze if the use of synthesized voice anchor emissions in auditory-perceptual evaluation improves intra- and inter-rater agreement.
Methods: This is a quantitative study. Thirty-two inexperienced evaluators were selected and performed two activities on a Programming Interface created by the authors: Active Calibrator Activity - auditory-perceptual evaluation of the roughness and breathiness parameters as 0-no deviation, 1-slight deviation, 2-moderate deviation, or 3-intense deviation of 25 voices with the support of anchored emissions of synthesized voices; and Inactive Calibrator Activity - auditory-perceptual evaluation of these same voices without the support of anchored vocal emissions.
Mental fatigue and sleepiness are well recognized determinants of human-error related accidents and incidents in aviation. In Brazil, according to the Center for Investigation and Prevention of Aeronautical Accidents (CENIPA), the rate of accidents in the aerial modal is 1 per 2 d. Human factors are present in 90% of these accidents.

Study Design: This is a quantitative nature study.
Methods: An auditory-perceptual training site was developed consisting of Programming Interface A, an auditory training activity, and Programming Interface B, a control activity.
Traditionally, the teaching of intonation on the non-tempered orchestral strings (violin, viola, cello, and double bass) has resorted to the auditory and proprioceptive senses only. This study aims at understanding the role of visual and tactile information in the control of the non-tempered intonation of the acoustic double bass. Eight musicians played 11 trials of an atonal sequence of musical notes on two double basses of different sizes under different sensorial constraints.
