摘要
根据嗓音-呼吸系统生理和生物物理原理,运用研制的嗓音测试系统,获取颈前V型槽处的传导语音信号,基于复倒谱技术提取声门下嗓音源特性。研究男女胸声区不同发声条件下声带振动和声门下嗓音源特性。结果表明,声门下嗓音源能够反映声带振动特征,是研究声带振动特性和喉部疾病诊断的一种有效方法。
Based on the physiology and biophysics of voice-respiration system, the voice production and aerodynamic coupling system can be divided into supra-glottal vocal tract, supra-glottal voice source, vocal cord, sub-glottal voice source, sub-glottal vocal tract, lung, respiratory sound source and lung-thorax sections. Using the voice functions measuring system developed, the transmitted sound signals were acquired. Based on complex cepstrum, the vocal tract vibrations and sub-glottal voice sources of both male and female in chest region were examined. Results showed vocal cord vibration modes and characteristics. It would be one of good methods for measurement of vocal cord vibration characteristics and diagnosis of thorax diseases.
