INTRODUCTION The aim of this study was to test the null hypothesis that voice parameters of post-laryngectomy patients using tracheo-oesophageal (TO) prosthetic valves are similar to those of normal laryngeal subjects. METHODS Thirty total laryngectomy patients and thirty normal controls were subjected to acoustic analysis of single voice recordings using a sustained vowel. Acoustic parameters including fundamental frequency, jitter, shimmer, harmonics-to-noise ratio and maximum phonation… CONTINUE READING
