摘要: 的 通过语音频谱分析探索评价高鼻音程度的客观指标。方法 选取四川大学华西口腔医院语音矫 治室保存的腭裂患者录音资料60份,采用阳宸VS-99语音工作站进行分析,获得低频区相对能量值(REL值);再由 专业语音治疗师和从未接触过语音治疗的口腔医师分别对这60份录音资料进行主观判听,获得专业主观判听值 和业余主观判听值。将3组数据进行统计学相关性分析。结果 REL值与专业、业余主观判听值间的相关系数分 别为0·272和0·274,为低度相关(P<0·05);专业和业余主观判听值之间为中度相关(r=0·663,P<0·01)。结论  REL值可作为评价腭裂患者高鼻音程度的一项客观参考指标。

Abstract: Objective To find an objective indexto describe the severity of hypernasality in cleft palate patients through speech spectroanalysis.Methods 60 audio records of cleft palate patients were analyzed by spectroanalysis, the relative energy in low frequency area (REL) was calculated in the LPC spectrogram. One experienced speech therapist and two nonprofessionals made perceptual judgments of the same records. Spearman correlation analysiswas conducted to test if the 3 groups of data have signifi- cant correlations.Results RELhad significant correlation with professional judgments (correlation coefficient was 0·272,P< 0·05) and nonprofessional judgments (correlation coefficient was 0·274,P<0·05).Conclusion RELcan be used as one ob- jective reference in the judgment of the severity of hypernasality.
