Abstract
There are many research tools which are also used for teaching the acoustic phonetics of speech rhythm and speech melody. But they were not purpose-designed for teaching-learning situations, and some have a steep learning curve. CRAFT (Creation and Recovery of Amplitude and Frequency Tracks) is custom-designed as a novel flexible online tool for visualisation and critical comparison of functions and transforms, with implementations of the Reaper, RAPT, PyRapt, YAAPT, YIN and PySWIPE F0 estimators, three Praat configurations, and two purpose-built estimators, PyAMDF, S0FT. Visualisations of amplitude and frequency envelope spectra, spectral edge detection of rhythm zones, and a parametrised spectrogram are included. A selection of audio clips from tone and intonation languages is provided for demonstration purposes. The main advantages of online tools are consistency (users have the same version and the same data selection), interoperability over different platforms, and ease of maintenance. The code is available on GitHub.

有许多研究工具,也用于教学语音节奏和语音旋律的声学语音学。但它们不是为教学情境而设计的,有些则有陡峭的学习曲线。craft(振幅和频率轨迹的创建和恢复)是一种全新的灵活的在线工具,用于可视化和功能和转换的关键比较,实现了reaper、rapt、pyrapt、yaapt、yin和pyslipe f0估计量、三个praat配置和两个专门构建的估计量pyamdf、s0ft。包括振幅和频率包络谱的可视化、节律区的光谱边缘检测和参数化谱图。为演示目的,提供了从音调和语调语言中选择的音频剪辑。在线工具的主要优点是一致性(用户具有相同的版本和数据选择)、不同平台上的互操作性以及易于维护。代码在GitHub上可用。
