Hi Welshwind, Thanks for pointing that out to me. After doing a little research into some journals of SLP on the web, it seems that there is some question as to the efficacy of whispering as a form of vocal rest. The research of which I was previously aware suggested that it was beneficial, however, there is some research that suggests that it may be harmful, as well. I would have to agree with the good doctor since it's better safe than sorry, and recommend against it now, since it is uncertain whether or not whispering will negatively impact the vocal folds' health. "Although whispering involves more severe hyperfunction in most patients, it does not seem to do so in all patients. In some patients, it may be less traumatic than normal voice." From: Laryngeal Hyperfunction During Whispering: Reality or Myth? . Journal of Voice , Volume 20 , Issue 1 , Pages 121 - 127 A . Rubin , V . Praneetvatakul , S . Gherson , C . Moyer , R . Sataloff "Laryngeal functioning during the production of whispered speech is not well understood. The efficacy of whispering as a means of voice rest is a common clinical concern that is unresolved. This investigation examined vocal-fold configuration, glottal size, and airway constriction by supraglottal structures during whispering." "However, for each dependent variable, individual subject differences tended to be considerably larger than any systematic effects due to whisper type or vowel."
