对正常嗓音个体的声门下气压、声门气流波形特征、声压级(SPL)和声谱斜率进行了研究。不同水平的声门下气压和不同的声门构型的组合可能会导致相同的SPL。相对较高的气压水平与陡峭的频谱斜率相关，反映出更正弦的声门波形和相对外展的膜性声门，这将导致F1的衰减。数据表明，颧骨间声门开口可以改变，而不会系统性地影响SPL或语音质量。结果表明，与生产相关的努力节约以及生理、声学和知觉限制的原则可能适用于语音生产。
Measures of inferred subglottal air pressure, glottal airflow waveform characteristics, sound pressure level (SPL) and the acoustic spectral slope were studied for individual speakers with normal voices. Combinations of different levels of sub-glottal air pressure and varying glottal configurations could result in the same SPL. Relatively high air pressure levels were associated with a steep spectral slope, reflecting a more sinusoidal glottal waveform and a relatively abducted membranous glottis, which would result in damping of F1. Data suggested that the interarytenoid glottal opening could vary without systematically affecting SPL or voice quality. The results indicate that the principles of production-related economy of effort and physiological, acoustic and perceptual constraints may apply to voice production.
