【摘要】 语音传输指数（Speech Transmission Index,STI）和言语可懂度指数（Speech Intelligibility Index,SII）是语言声厅堂中常用的言语可懂度客观评价方法，其评价准确性受参量模型所采用的频带权重函数的影响较大。频带权重函数的确定受很多因素的影响。基于此，综述频带权重函数的研究方法、影响因素以及当前应用的局限性。当前频带权重函数的研究受研究方法标准化欠缺、多因素耦合效应表征不足、听觉感知机制建模局限等的影响较大，需构建综合心理声学、语言学及统计学理论的多维度分析框架，发展频带权重函数计算模型，以提升复杂声学场景下言语可懂度的评价效度。更多还原

【Abstract】 Speech Transmission Index(STI) and Speech Intelligibility Index(SII) are commonly used objective evaluation methods for speech intelligibility in auditorium acoustics, both heavily influenced by the frequency-band weighting functions adopted in parametric models. The determination of these weighting functions is affected by many factors. This paper systematically reviews the research methods, influencing factors, and current limitations in the application of frequency-band weighting functions. Current research is significantly constrained by the lack of standardized methodologies, insufficient characterization of coupled multi-factor effects, and limitations in modeling auditory perception mechanisms. There is a need to develop a multidimensional analytical framework integrating psychoacoustics, linguistics, and statistical theories to advance computational models of frequency-band weighting functions, thereby enhancing the evaluation validity of intelligibility in complex acoustic environments.更多还原
