本研究的目的是评估几种声学措施在预测呼吸等级的有效性。录音是由8名正常男性和7名正常女性产生正常发声，适度呼吸，非常呼吸持续元音。20名听众使用直接幅度估计程序评定呼吸的程度。声学测量包括：（a）信号周期性，（B）第一谐波振幅，和（c）频谱倾斜。周期性措施提供了最准确的预测感知呼吸，约占80%的变化呼吸评级。第一谐波的相对振幅与呼吸等级中度相关，两个频谱倾斜的措施与感知呼吸弱相关。
The purpose of this study was to evaluate the effectiveness of several acoustic measures in predicting breathiness ratings. Recordings were made of eight normal men and seven normal women producing normally phonated, moderately breathy, and very breathy sustained vowels. Twenty listeners rated the degree of breathiness using a direct magnitude estimation procedure. Acoustic measures were made of: (a) signal periodicity, (b) first harmonic amplitude, and (c) spectral tilt. Periodicity measures provided the most accurate predictions of perceived breathiness, accounting for approximately 80% of the variance in breathiness ratings. The relative amplitude of the first harmonic correlated moderately with breathiness ratings, and two measures of spectral tilt correlated weakly with perceived breathiness.
