This is the single most important factor. Use of voice during laryngitis results in incomplete or delayed recovery. Complete voice rest is recommended although it is almost impossible to achieve. If the patient needs to speak, the patient should be instructed to use a "confidential voice;" that is, a normal phonatory voice at low volume without whispering or projecting.
