  2. Dysphonia must be present for at least one month duration.
  3. May have vocal cord nodules present.
  4. Pre-enrollment flexible fiberoptic laryngoscopy must not show any potentially life-threatening cause, including but not limited to laryngeal papillomatosis, congenital glottic webs, vocal cord paralysis, or benign and malignant neoplasms.

Exclusion Criteria:

  1. Dysphonia must not be due to a potentially life-threatening cause, such as laryngeal papillomatosis, congenital glottic webs, vocal cord paralysis, or benign and malignant neoplasms. This will be determined by visualization with flexible fiberoptic laryngoscopy.
  2. Dysphonia must not be due to an acute upper respiratory infection.
  3. Must not have been treated with proton pump inhibitor medication in the past 12 months.
  4. Inability of child to cooperate with recording of voice for analysis.
