目的 :探讨全程取样与分段取样对嗓音分析结果的影响。方法 :比较全程 3s取样与平稳段 1s、样本的前 1s及后 1s取样时 ,嗓音分析结果并行统计学检验。结果 :分段取样可使各参数明显更接近正常值。结论 :分段取样行嗓音分析会掩盖患者病情的程度 ,不宜采用。
Objective: To investigate the effect of full sampling and sub-sampling on voice analysis results. Methods: Comparing the sampling of 3s and the stationary phase for 1s, sampling the first 1s and the last 1s of the sample, the voice analysis results were statistically tested. Results: Sectional sampling allows each parameter to be significantly closer to normal. Conclusion: Segmented sampling voice analysis will cover the extent of the patient’s condition, should not be used.
