Electroglottographic analysis of valved speech following total laryngectomy.
Twenty-seven total laryngectomy patients (19 males and 8 females) and 18 normal control subjects (10 males and 8 females) were subjected to electroglottography-based single voice recordings using sustained vowels and connected speech. The results showed poorer values and larger variability for all the voice measures for the total laryngectomy patients (TO speech) as compared to that of normal subjects. There were statistically significant differences (p<0.05) for all study parameters between the TO and normal speech. This study shows that robust and reliable data can be obtained using electroglottography in laryngectomees with both a sustained vowel and connected speech. Using these parameters, TO speech is significantly different from normal speech and is highly variable. This methodology has enormous potential for further investigations in laryngectomees and other patients with head and neck cancer.
