Proposal of requirements for the development of a training simulator for the auditory-perceptual judgment of voice

to identify a set of requirements for the development of an auditory-perceptual training simulator (APT) based on the experience of professors who provide APT.

This is a cross-sectional, descriptive study with a quantitative approach. Twenty-two professors answered an online questionnaire containing 31 items related to APT, involving items about the professional profile, conditions for APT in undergraduate and postgraduate courses in Speech Therapy, APT structure, and evaluation of the APT effect.

it was observed that there is a variation in APT procedures performed in Brazil. The main requirements indicated by the respondents for the APT involve the use of synthesized voices in the initial moments, followed by human voices later; the use of speech tasks with sustained vowels and connected speech; the insertion of complementary information such as gender, age, the profession of the speaker and the spectrography of the vocal signal; training with a minimum time of six hours; the evaluation of the training effect by comparing intra- and inter-judge agreement before and after training; the addition of the parameters of general degree of vocal deviation, roughness, breathiness, and strain; the use of validated continuous and numerical scales; and offering it from the second year of the undergraduate program.

although there is variability in the response of experts, a minimum set of requirements indicated for performing APT with new judges was identified.
