摘要(Abstract)：

在TD-PSOLA语音合成系统中,基音标注的准确性是一个非常重要的因素。针对传统的短时自相关函数和小波算法准确性不高和没有自适应性的缺点,提出一种基于Hilbert-Huang变换的基音标注方法。该算法通过Hilbert-Huang变换分析语音,具有自适应性,根据自身情况选择基函数,分解过程满足条件自动停止。采用文中自适应算法对整段非平稳语音信号进行基音标注,其中浊音段、过渡段采用Hilbert-Huang变换进行标注,清音段、非语音段用相近基音周期插值。实验证明,相比自相关方法、小波方法,文中算法反映了一帧内准周期的细微变化,适应性较好。对于频率不同的男声和女声,准确度可达到90%以上。
