[Vocal and behavioral adaptations of program sellers in work situation]

Area of Science:

• Occupational health
• Speech science
• Acoustics

Background:

• Program sellers at Parisian Operas operate in high-noise environments.
• The audibility and intelligibility of their announcements are crucial for their work.

Purpose of the Study:

• To investigate vocal health risks for Parisian Opera program sellers.
• To identify vocal adaptations used by program sellers in noisy opera house settings.

Main Methods:

• A mixed-methods approach was employed, including questionnaires.
• Acoustic analysis of recorded speech samples.
• Videolaryngostroboscopy and objective/subjective vocal function assessments.

Main Results:

• Vocal risk factors and symptoms of vocal fatigue were identified in program sellers.
• Adaptations consistent with
• Lombard Speech
• were observed.
• Common and individual speech specificities, including prosodic and acoustic variations, were noted.

Conclusions:

• Program sellers exhibit vocal fatigue and risk factors, suggesting a need for preventive measures.
• Vocal adaptations, particularly
• Lombard Speech
• , are utilized to overcome high-noise environments.
• Understanding these adaptations can inform targeted vocal health interventions.
