    Abstract:
    OBJECTIVE: To evaluate the quality of voice restored by using a tracheoesophageal slit-like fistula objectively through acoustic analysis. METHODS: Seven objective voice parameters (fundamental frequency, intensity, duration, formant F1, F2, F3 and their energy, jitter, and shimmer) of esophageal speech, Blom-Singer prosthesis voice, tracheoesophageal slit-like fistula voice, primary or modified surgical restored, and normal voice were analyzed and compared. RESULTS: T test was used for statistical analysis. The maximum phonation time of slit-like fistula voice was shorter than that of normal voice, longer than that of esophageal voice, no significant difference compared with that of Blom-Singer prosthesis voice. Its sound intensity of it was similar to that of normal voice and Blom-Singer voice, better than that of esophageal voice. Its fundamental frequency was lower than that of normal voice. Its shimmer and jitter was more than that of normal voice, less than that of esophageal voice, and similar to that of Blom-singer one. Compared with esophageal voice, all formants but F1 of it were not statistically different. No statistical difference between the 2 groups of slit-like fistula patients, i.e., the instant slit-like fistula construction after total laryngectomy and the second stage slit-like fistula construction. CONCLUSION: The voice quality of the patients with tracheoesophageal slit-like fistula is similar to that of the normal and could meet the needs of daily life.
