In this chapter, I divide Shanghai sign utterances into intonational phrases based on the principle of "pause", study the duration of "pause", analyze the prosodic markers at the end of intonational phrases, such as manual markers include holding, amplitude and repetition of two hands and so on, and non-manual markers including head nod, eye blinks and so on. This chapter selects natural corpus and uses ELAN to label it in several layers and choose markers that appeared frequently to analyze and summarize them. According to the analysis, the "pause" time between intonational phrases varies according to gender, age, corpus property and environment, but most of them are distributed between 120ms and 300ms. At the end of an intonational phrase, there is one or more of such markers generally present, such as hand holding, large amplitude, repetition, nodding, blinking, and the like.
