Five cases are presented. One is a case of ventricular phonation of iatrogenic origin and the remaining four had undergone laryngectomy for carcinoma of the larynx. Points of interest are discussed, particularly the constant ventricular fold phonation of the first case and the clear harmonic structure present in the voice of one of the laryngectomy cases who has both esophageal speech and pharyngeal phonation.
