The need for an objective assessment of voice quality can be seen in the increasing use of acoustic analysis methods for clinical diagnosis and research. The hoarseness diagram allows clinicians to objectively describe even highly disturbed or aphonic votes. Its application possibilities are illustrated in three case studies in which changes in voice quality were monitored during voice rehabilitation. The distributions of voice groups that were defined on the basis of specific pathophysiological phonation conditions were then compared for their acoustic differences. The groups comprised various phonation conditions after the resection of laryngeal tumors and different types of laryngeal paralyses. Interpretation of the results suggests a direct correspondence of the hoarseness diagram coordinates and the irregularity of vibration on the one side and the degree of glottal closure on the other. This illustrates the potential usefulness of the hoarseness diagram in a clinical context.
随着声学分析方法在临床诊断和研究中的应用日益增加，对嗓音质量进行客观评估的需求也愈发明显。嘶哑图使临床医生能够客观地描述即使是高度紊乱或失音的嗓音。通过三个案例研究展示了其应用可能性，在这些案例中，在嗓音康复过程中监测了嗓音质量的变化。然后比较了基于特定病理生理发声条件定义的嗓音组的分布情况，以分析其声学差异。这些组包括喉肿瘤切除后的各种发声条件以及不同类型的喉麻痹。结果解释表明，嘶哑图坐标一方面与振动不规则性直接对应，另一方面与声门闭合程度直接对应。这说明了嘶哑图在临床环境中的潜在用途。
