基于小波的时间频率表示的各种信号的可靠代表感知相关的模式在各种空间和时间尺度上的噪声鲁棒的方式。在这里，我们提出了一个基于小波的可视化和分析工具的韵律模式，特别是语调。该方法的适用性进行评估，通过比较其预测的单词顺序对手动标签在语料库中的900句。此外，该方法的可视化的潜力证明了几个例子相比，更传统的可视化方法的句子。最后，一些进一步的应用建议和方法的局限性进行了讨论。
Wavelet based time frequency representations of various signals are shown to reliably represent perceptually relevant patterns at various spatial and temporal scales in a noise robust way. Here we present a wavelet based visualization and analysis tool for prosodic patterns, in particular intonation. The suitability of the method is assessed by comparing its predictions for word prominences against manual labels in a corpus of 900 sentences. In addition, the method’s potential for visualization is demonstrated by a few example sentences which are compared to more traditional visualization methods. Finally, some further applications are suggested and the limitations of the method are discussed.
