Glottal Function and Vocal Self-Perception in Municipal School Teachers

52 teachers from municipal schools in Lagarto participated in a study correlating self-reported and expert-assessed vocal health. The study found 80% of teachers had voice changes according to auditory-perceptual evaluation, while 59.6% self-reported vocal changes. This dataset was created by Elisângela Santos Carregosa from the analysis of Glottal Function Index questionnaires and Consensus Protocol evaluations.

Use Cases

• Correlating self-reported vocal symptoms like 'vocal fatigue' with expert-identified symptoms like 'hoarseness'.
• Analyzing demographic factors (age, gender) in relation to vocal health outcomes among educators.
• Training models to predict vocal self-awareness gaps based on questionnaire and evaluation protocol data.

Strengths

• Includes data from 52 participants with specific gender breakdown (39 women, 13 men).
• Combines two distinct assessment tools: a self-assessment questionnaire and an expert auditory-perceptual evaluation.
• Reports specific prevalence rates for vocal changes (80% and 59.6%) and common symptoms.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the single-city (Lagarto) sample.
