摘　　要：A phonetic experiment was conducted to investigate whether the acoustic features of discourse focus were subjected to the influence of discourse hierarchy. Six speakers were instructed to read aloud 32 groups of experimental material. The duration, pitch range, f0 maxima, and f0 minima of foci in different discourse hierarchies were extracted for statistical analysis. The results revealed that foci embedded higher in the discourse hierarchy had relatively longer duration and more expanded pitch range; moreover, with the variation of tone combination, foci in different discourse hierarchies differed remarkably in their manifestation of f0 maxima and f0 minima features. Specifically speaking, for non-low tone combinations, foci in higher discourse hierarchy were pronounced with higher f0 maxima, while for low-tone combinations, foci in higher discourse hierarchy were articulated with lower f0 minima.A phonetic experiment was conducted to investigate whether the acoustic features of discourse focus were subjected to the influence of discourse hierarchy.
