Post-low bouncing is a phenomenon whereby after reaching a very low pitch in a low lexical tone, F(0) bounces up and then gradually drops back in the following syllables. This paper reports the results of an acoustic analysis of the phenomenon in two Mandarin Chinese corpora and presents a simple mechanical model that can effectively simulate this bouncing effect. The acoustic analysis shows that most of the F(0) dynamic features profiling the bouncing effect strongly correlate with the amount of F(0) lowering in the preceding low-tone syllable, and that the additional F(0) raising commences at the onset of the first post-low syllable. Using the quantitative Target Approximation model, this bouncing effect was simulated by adding an acceleration adjustment to the initial F(0) state of the first post-low syllable. A highly linear relation between F(0) lowering and estimated acceleration adjustment was found. This relation was then used to effectively simulate the bouncing effect in both the neutral tone and the full tones. The results of the analysis and simulation are consistent with the hypothesis that the bouncing effect is due to a temporary perturbation of the balance between antagonistic forces in the laryngeal control in producing a very low pitch.
