What is vocal effectiveness in lyrical singing in comparison to speech? Our study tries to answer this question, using vocal efficiency and spectral vocal effectiveness.
Vocal efficiency was mesured for a trained and untrained subject.
According to these invasive measures, it appears that the trained singer uses her larynx less efficiently. Efficiency of the larynx in terms of energy then appears to be secondary to the desired voice quality. The acoustic measures of spectral vocal effectiveness of vowels and sentences, spoken and sung by 23 singers, reveal two complementary markers: The "singing power ratio" and the difference in amplitude between the singing formant and the spectral minimum that follows it. Magnetic resonance imaging and simulations of [a], [i] and [o] spoken and sung show laryngeal lowering and the role of the piriform sinuses as the physiological foundations of spectral vocal effectiveness, perceptively related to carrying power.
These scientifical aspects allow applications in voice therapy, such as physiological and perceptual foundations allowing patients to recuperate voice carrying power with or without background noise.
与言语相比，抒情歌唱中的发声效果如何？我们的研究试图通过发声效率和频谱发声效果来回答这个问题。
对一名经过训练和一名未经训练的受试者进行发声效率测量。
根据这些侵入性测量结果，似乎经过训练的歌手使用喉部的效率较低。就能量而言，喉部的效率似乎次于所需的嗓音质量。对23名歌手所唱和所说的元音及句子的频谱发声效果进行的声学测量揭示了两个互补的指标：“歌唱功率比”以及歌唱共振峰与其后的频谱最小值之间的振幅差异。对[ɑ]、[i]和[ɔ]的言语和歌唱进行的磁共振成像及模拟显示，喉部下降以及梨状窦的作用是频谱发声效果的生理基础，在感知上与传播力相关。
这些科学方面的内容可应用于嗓音治疗，比如其生理和感知基础可使患者在有或无背景噪音的情况下恢复嗓音传播力。
