ACOUSTIC PARAMETERS AND SPEECH ANALYSIS AFTER SUPRACRICOID HEMILARYNGOPHARYNGECTOMY

Selected characteristics of speech and voice were compared in 10 patie nts who had undergone supracricoid hemilaryngopharyngectomy (SCHLP) an d 20 normal adult laryngeal (NAL) speakers, Durational features of tap e-recorded speech samples were measured using a stopwatch. Frequency f eatures were analyzed with the Computerized Speech Lab and the multidi mensional voice program. SCHLP speech proved comparable to NAL speech in average fundamental frequency, speech rate, and group phrasing. SCH LP speech and voice mere statistically less efficient than NAI, speech in fundamental frequency range, jitter, shimmer, noise-to-harmonic ra tio, and maximum phonation time. Age, associated cricopharyngeal myoto my, postoperative radiation therapy, and time elapsed from SCHLP compl etion were not statistically related to the speech and voice parameter s of SCHLP speakers.
