Voice Outcomes After Transoral Laser Microsurgery for Early Glottic Cancer—Considering Signal Type and Smoothed Cepstral Peak Prominence

摘要: Summary Objectives/Hypotheses This study proposed the use of signal typing and acoustic measures experimentally validated for aperiodic voices to investigate voice outcomes after transoral laser microsurgery (TLM) early glottic carcinoma. It was interest whether type pitch-tracking indicators would reveal unreliable perturbation noise measures. As an alternative, smoothed cepstral peak prominence (CPPS) used first time in this population. Study Design A descriptive patients treated with TLM Methods All participants (n=14) performed a series vocal tasks. Narrowband spectrograms were generated from recordings classified into one four types. The periodic or near-periodic signals only reported. CPPS sustained vowel (CPPS-/a/) connected speech (CPPS-s) calculated all participants. relationship between tumor factors investigated. Results Nine 14 had 3 signal. Three considered reliable analysis. Absolute jitter, %jitter, %shimmer, signal-to-noise ratio low; however, CPPS-/a/ CPPS-s amplitudes below normal range most Involvement anterior commissure, number episodes, post-surgery associated worse outcomes. There strong correlations type, CPPS-/a/, indicators. Conclusions limitations analysis should be when analyzing TLM. Signal before conducting may more outcome
