The linguistic constraints and phrase-length constraints are the most important factors for Chinese prosodic phrasing in the natural speech. This paper presents a linguistic constraint model and a phrase-length constraint model to describe these two processes independently. Therefore, each part can be described in detail. In the linguistic constraints model, Chunk (base phrase) is considered as an important basic unit. And an HMM is used to model the phrase-length constraints, which concerns the distribution of the prosodic phrase lengths and the relationship between the prosodic phrase and the prosodic words. Then a k-candidate method is introduced to combine these two models. This approach makes full use of the linguistic constraints and the phrase-length constraints. The experiments show that this approach achieved a perfect performance with the phrasing f-score 82.9%.
