The pitch phase of a syllable (PPS) can be divided into a pitch transition phase (PTrP) and a pitch target phase (PTaP). To analyze the relationships between the duration of the PTrP and the pitch range of the PTrP, the pitch range of the PTaP, and the total duration of the PPS, 306 disyllable combinations were selected from a corpus to generalize a linear regression model, which can be applied to predict the duration of the PTrP. In this model, the duration of the PTrP has a positive relationship with the pitch range of the PTrP and the total duration of the PPS, while a negative relationship with the pitch range of the PTaP. Moreover, with the increase of the total duration of the PPS, the duration of the PTrP will increase faster. By using this linear regression model to predict the duration of the PTrP, the relative coefficient between predicted value and the metrical value is 0.853.
