嗓音客观评估的研究进展

嗓音是一个复杂的多维现象,它是通过肺气流驱动声带振动继而被听者感知到的声音。嗓音疾病最早依靠富有经验的喉科医生的主观判断,由于受临床经验、个人习惯等一些主观因素的影响,难免出现误诊、漏诊。后来出现了嗓音的客观检测方法,随着现代计算机技术、电子技术的飞速发展,催生了一系列新的嗓音检测手段,计算机仿生功能检

Reasearch progress of the objective voice assessment

The voice is a complex multidimensional phenomenon. It is a drive through the lung airflow to vibrate the vocal cords, and then be perceived by the listeners. A multidimensional set of minimal basic measurements suitable for the voice diseases are proposed by the Committee on Phoniatrics of the European Laryngological Society in 2000. It includes five different aspects: the subjective physician perception (grade, roughness, breathiness), and subjective rating by the patient, videostroboscopy (closure, regularity, mucosal wave and symmetry), acoustics analysis and aerodynamics measurements. The first three are the subjective assessment of voice, these are not to be discussed in tis article. Only objective assessments of the voice and the latest research progress are summarized below.
