ProsodyPro generated the intrinsic duration of each syllables and turned all the syllable durations into a normalized time.
duanmu (2007) maintained the view that all Mandarin stressed syllables (i.e., syllables carrying lexical tones) occupy two rime slots, that is, although a simple rime, V in a stressed CV is counted as occupying two rime slots, and in this view, the length of V in a stressed CV syllable is considered the same as the length of VG and VN in CVG and CVN syllables.
