5 normal speakers and 5 speakers with congenital upper motor-neuron damage repeatedly spoke a three-work sentence stressing the first, second, or third words. Fundamental frequency was measured for each word and over each sentence. Analysis showed that the spastics' mean fundamental frequency was significantly higher than the normals', regardless of utterance. Also, spastics were more restricted in their prosodic maneuvering above this average fundamental frequency. Despite this finding, the spastics were capable of producing consistent stress patterns with normal variability.
5名正常说话者和5名患有先天性上运动神经元损伤的说话者反复说出一个由三个单词组成的句子，分别强调第一个、第二个或第三个单词。测量了每个单词以及每个句子的基频。分析表明，无论发音如何，痉挛患者的平均基频显著高于正常人。此外，痉挛患者在高于这个平均基频的韵律操纵方面受到更多限制。尽管有这一发现，但痉挛患者能够产生具有正常变异性的一致重音模式。
