A speech production experiment with electroglottography investigated how voicing is affected by consonants of differing degrees of constriction. Measures of glottal contact [closed quotient (CQ)] and strength of voicing [strength of excitation (SoE)] were used in conditional inference tree analyses. Broadly, the results show that as the degree of constriction increases, both CQ and SoE values decrease, indicating breathier and weaker voicing. Similar changes in voicing quality are observed throughout the course of the production of a given segment. Implications of these results for a greater understanding of source-tract interactions and for the phonological notion of sonority are discussed.

辅音压缩对语音质量的影响。

带有电声描记法的语音产生实验研究了不同收缩程度的辅音如何影响发声。在条件推理树分析中使用了声门接触[封闭商（CQ）]和发声强度[激发强度（SoE）]的量度。广泛地，结果表明，随着收缩程度的增加，CQ和SoE值均降低，表明呼气更加通畅和减弱。在整个给定片段的生产过程中，会观察到语音质量的类似变化。讨论了这些结果对更好地理解源-场相互作用和声音的语音学意义的含义。
