PMID 37820100WHAT IT FOUND
Experienced voice trainers mostly agree voice listening training should begin after early coursework, start by detecting vocal deviation, then identify dominant quality, then rate severity.
Training hours, voices, scales, and effect checks varied widely.
Key findings
01Most professors reported that auditory-perceptual training of voice is offered in or after the second undergraduate year, and all who believed there is a better time said it should be after the second year.
02The preferred training sequence was to first identify the presence or absence of vocal deviation, then assess the predominant vocal quality, and finally assess the degree of vocal deviation.
03Classroom training hours varied from less than 2 hours to more than 8 hours, most used human voices, most did not use a simulator or game, and about 60% did not assess reliability after training.

What it does not show
Only 22 professors responded, and many e-mails were not answered even after three sends, so the results reflect a small group of academic voice specialists. The study asked professors about their training opinions and did not test a simulator, student learning, or patient voice outcomes. The proposed requirements are expert recommendations, not tested interventions, and the authors say they can change as studies advance. Participants were mainly from São Paulo and three regions of Brazil, so the findings may not apply to other countries or clinical settings. The questionnaire was developed and adapted for this study, not reported as a validated instrument for voice training requirements.
The easy way to misread this
Do not read the proposed simulator requirements as evidence that a simulator improves voice judgment. This paper surveyed professors' opinions and did not test a simulator or patient outcomes.
