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 time were analysed. RESULTS: Poorer values were found as well as larger variability for all the voice parameters for the total laryngectomy patients using TO voice compared with those of normal subjects. There were statistically significant differences (p<0.05) for all studied parameters between the TO and normal speech. CONCLUSIONS: Alaryngeal speech with TO voice prosthesis is not yet comparable to laryngeal speech.
