OBJECTIVES: To provide teachers and community schools that adopt the extension program Health Fairs with guidelines on vocal health to help the teacher in finding alternatives for proper use of the voice suited to the working routine. To recognize possible vocal changes and practical activities to develop a better knowledge of aspects such as breathing and voice preparation for professional practice. MATERIAL AND METHODS: The workshops are conducted in a group as an informal "chat" where teachers listen to questions and experiences in a relaxed and interactive atmosphere. Initially, the theoretical aspects are developed, then practical exercises, such as vocal warming, are performed. This teaches participants how to prepare for the excessive use of voice. During the workshop, apples and mineral water are provided, which are symbols of a polished voice. Educational posters are displayed in the workshop environment, and selected health education materials, folded in the shape of apples, are supplied. RESULTS AND CONCLUSIONS: From January 2012 through June 2013, 7 voice workshops were held in different schools and were attended by 167 people, the majority of whom were teachers. There is a shortage in the supply of knowledge to professionals who suffer from excessive use of voice such as teachers. The impact of the workshop is assessed through reports according to positive evaluations such as routine changes and acknowledgement of the importance of participation.
