1) pitch detection
基音提取
1.
Wavelet transform is very effective for picking up the pitch detection from a single source,but there is no effective way to obtain the pitch information from the pitch detection in overlapping speech with multi-sources.
小波变换对单一信号源的基音提取非常有效,但在多音源混叠语音的基音提取中则无法有效地获得基音信息。
2.
The continuous Chinese tone of three syllabic word is very complicated and its pitch detection is more difficult than that of isolated word because of the effects of vocal response,syllable conjunction,coarticulation and tone sandhi.
连续的汉语三字词声调 ,由于受声道响应、音联、协同发音和变调规律等的影响 ,情况很复杂 ,故其基音提取远远较孤立字困难。
3.
An approach of the pitch detection for obtaining speech tone of Chinese trisyllabic words on the basis of the wavelet transforms is proposed .
给出了一种基于小波变换的汉语三字词基音提取方法。
3) pitch estimation
基音提取
1.
Compared with conventional MBELP algorithm, this algorithm improves pitch estimation and unvoice/voice decision.
与传统的MBELP算法相比，该算法在基音提取和清／浊音判决上采取了一些改进措施，使得合成语音质量有一定的提高。
4) pitch tracking
基音周期提取
1.
A novel pitch tracking method based on FFT-ACF and estimation of pitch candidates;
基于FFT-ACF和候选值估计的基音周期提取方法
2.
To reduce the halving and the doubling errors in pitch tracking,an algorithm based on a combined magnitude difference function is proposed in this paper.
为了减少基音周期提取中的倍频和半频错误,进行更准确的基音周期估计,提出一种基于混合幅度差函数的基音周期提取方法。
