Speech Prosody 2006
This paper investigates the variability of break allocations within Chinese sentences by perceptual experimentation. The results confirm the existence of prosodic chunks. We have found that (1) prosodic chunks are the basic units in the rhythmic organization of Chinese utterances (breaks can generally be allocated by chunk boundaries and breaks placed within a chunk will significantly decrease the naturalness of synthesized speeches); (2) given prosodic chunks, multiple break solutions are acceptable. Furthermore, breaks can be allocated by chunk boundaries using simple rules that impose a length-balance constraint without considering the syntax or semantic structure of a sentence.
