【摘要】 用LPC(Liner-Prediction-Coefficient)分析得到语音信号线性系统模型,并将此模型用于耳鸣匹配声源,再用双线性转换函数对耳鸣匹配声源进行频谱转换。通过将频谱转换前后耳鸣匹配声源的平均幅度比值和固定门限值进行比较,来扩大双线性转换函数中频率弯折系数的选择范围,从而为耳鸣掩蔽治疗合成出更加丰富的耳鸣匹配声源。更多还原

【Abstract】 LPC(Liner-Prediction-Coefficient) analysis method is used to build linear system model for speech signals,and then this model is applied to tinnitus matching sound sources.Speech spectral is shifted by frequency spectrum conversion function based on the bilinear transformation.For enlarging the frequency spectrum warping coefficient range to synthesize more extensive tinnitus matching sound sources for tinnitus treat,the average amplitude ratio between the original tinnitus matching sound and the one after frequency spectrum conversion is compared with the fixed threshold quantity.更多还原
