Summary
This study found that vocal training did not reduce vocal attrition symptoms in telemarketers. However, training may offer protective benefits against symptom development and improve vocal communication skills.
Area of Science:
- Occupational Health
- Speech-Language Pathology
- Communication Sciences
Background:
- Telemarketers are at risk for vocal attrition symptoms due to high vocal demand.
- Existing vocal training programs' effectiveness in this population is not well-established.
Purpose of the Study:
- To evaluate the effectiveness of an 8-week vocal training program on vocal attrition symptoms in telemarketers.
- To assess the impact of vocal training on telemarketers' use of voice as a communication tool.
Main Methods:
- A total of 71 telemarketers participated.
- A subset (n=28) validated the Vocal Symptoms questionnaire.
- 43 participants were randomized into an 8-week vocal training group (n=14) or a control group (n=29).
- Post-training questionnaires assessed symptom occurrence and perceived benefits.
Main Results:
- The vocal training program did not significantly reduce the occurrence of vocal attrition symptoms.
- A potential increase in symptoms was observed in the untrained control group.
- Telemarketers in the vocal training group reported improvements in using their voice as a communication tool.
Conclusions:
- The tested vocal training program was not effective in preventing vocal attrition symptoms in telemarketers.
- Vocal training may act as a protective factor against symptom development.
- The training demonstrated benefits in enhancing vocal use for communication purposes.
