虽然语音韵律特征在语言信息的传递中起着重要的作用，但对其在语音感知过程中的作用进行定量分析的实验却相当少见。作为澄清和制定的过程中，三个知觉实验进行了一步。在第一个实验中，合成语音的孤立的话后，口音类型的操作。研究结果表明，韵律特征对词汇感知有重要影响，尤其是对第一类口音的词汇感知。实验二采用门控范式对自然词进行实验。使用门控话语作为刺激，正确识别所需的最小时间进行了调查，每个口音类型的话。结果表明，利用韵律特征，第1类重音词的感知完成时间早于其他重音类型的词。在最后一个实验中，句子刺激合成后操纵短语和重音成分的基频轮廓。结果表明，一个短语组件，即使是一个小的命令幅度，可以组在一个短语单元的话，因此，可以作为一个线索，用于检测句法结构。
Although prosodic features of speech are known to play an important role in the transmission of linguistic information, experiments are rather rare on the quantitative analysis for their roles in the speech perception process. As a step toward the clarification and formulation of the process, three perceptual experiments were conducted. In the first experiment, synthetic speech of isolated words were generated after accent type manipulation. Results showed that the prosodic features are important for word perception especially for the case of type 1 accent. The gating paradigm was applied to natural word utterances in the second experiment. Using the gated utterances as stimuli, the minimum period required for the correct identification was investigated for words with each accent type. Results showed that, utilizing the prosodic features, the perception of words with type 1 accent completes earlier than that of words with other accent types. In the last experiment, sentence stimuli were synthesized after manipulating phrase and accent components of the fundamental frequency contour. Results showed that a phrase component, even with a small command magnitude, can group words in a phrase unit, and, thus, can work as a cue for detecting syntactic structures.
