摘 要：目的探讨嗓音的客观多参数检测与主观听觉评估的相关性,建立嗓音客观多参数评估模式,实现嗓音评估的客观化、数据化.方法声音样本采自135例声音嘶哑患者和29例嗓音正常者.客观检测采用法国开发的"EVA"嗓音工作站,测试对象发长元音/α:/时,检测下列参数:基频(F0)、音强(intensity)、基频微扰(jitter)、信噪比(signal-to-noise ratio,SNR)、Lyapunov系数、口腔气流量(oral airflow,OAF)、音域(range)及最大发声时间(maximumphonatory time,MPT);发/pα/音时,检测声门下压(estimated subglottic pressure,ESGP).主观听觉评估采用日本言语语音学会声音嘶哑评估GRBAS系统中的总嘶哑度(grade,G)4级评估标准.所有受试者以自然的音调及音强读一段统一的标准文字,听评委由4名嗓音学家组成.结果应用判别分析方法,建立了7参数客观评估模式(音域、Lya-punov系数、声门下压、最大发声时间、口腔气流量、信噪比和基频).客观评估结果与主观评估结果的一致性达到84%.结论嗓音的客观检测是多参数的,客观评估能够反映出主观听觉印象.
