Whispering may cause more laryngeal trauma than normal speech for most patients, increasing supraglottic hyperfunction. However, some individuals experience less vocal fold strain when whispering.

Area of Science:

  • Otolaryngology
  • Speech-Language Pathology
  • Laryngeal Physiology

Background:

  • Conventional wisdom suggests whispering causes more laryngeal trauma than normal speech.
  • This hypothesis has lacked extensive fiberoptic examination data in patient series.

Purpose of the Study:

  • To investigate the effects of whispering on laryngeal function compared to normal speech.
  • To assess vocal fold closure and supraglottic hyperfunction during whispered phonation.

Main Methods:

  • Fiberoptic examinations of 100 patients with voice complaints were reviewed.
  • Patients counted from 1 to 10 in both normal and whispered voices.
  • Supraglottic hyperfunction and vocal fold closure were compared between phonation types.

Main Results:

  • 69% of patients showed increased supraglottic hyperfunction during whispering.
  • 13% exhibited less severe hyperfunction, and 18% showed no change.
  • The inverted Y glottal configuration was common during whispering, with 12 patients having no true vocal fold contact.

Conclusions:

  • Whispering increases laryngeal hyperfunction in the majority of patients.
  • However, whispering may be less traumatic than normal voice for some individuals.
  • Laryngeal trauma from whispering is variable among patients.
