选择的特点进行了比较，在语音和声音的28例患者治疗的环状软骨上喉部分切除术（SCPL）和14个正常的成人喉（NAL）扬声器。录音带记录的语音样本测量的持续时间的功能与秒表。频率特征进行了分析与计算机语音实验室和多维语音程序。SCPL语音被证明在平均基频上与NAL语音相当。SCPL语音和声音的统计效率低于NAL语音的基本频率范围，抖动，闪烁，噪声谐波比，最大发声时间，语音速率和短语分组。杓状软骨切除术的完成并没有统计学上改变SCPL扬声器的持续时间和频率特征。在SCPL的发言者1）平均基频统计较高（p =.02）与接受环舌骨固定术的患者相比，接受环舌骨会厌固定术的患者中，2）最大发声时间与患者年龄有统计学相关性（p = 0.002），3）抖动和闪烁值与自SCPL完成以来经过的时间具有统计学相关性（p = 0.01和（p = 0.005））。这些发现的解释和影响进行了讨论。
Selected characteristics were compared in the speech and voice of 28 patients treated with a supracricoid partial laryngectomy (SCPL) and of 14 normal adult laryngeal (NAL) speakers. Tape-recorded speech samples were measured for durational features with a stopwatch. Frequency features were analyzed with the Computerised Speech Lab and a multidimensional voice program. The SCPL speech proved comparable to NAL speech in average fundamental frequency. The SCPL speech and voice were statistically less efficient than NAL speech in fundamental frequency range, jitter, shimmer, noise to harmonics ratio, maximum phonation time, speech rate, and phrase grouping. The completion of an arytenoid cartilage resection did not statistically modify the duration and frequency features of SCPL speakers. Among SCPL speakers 1) the average fundamental frequency was statistically higher (p =.02) in patients who underwent a cricohyoidoepiglottopexy when compared to patients who underwent a cricohyoidopexy, 2) the maximum phonation time was statistically related to the patient's age (p =.002), and 3) the jitter and shimmer values were statistically related (p =.01 and (p =.005) to the time elapsed since SCPL completion. Explanations and implications of these findings are discussed.
