| 中文摘要: |
| 本文介绍了一种无侵入、直接、客观、定量地反映发声过程中声带振动特性及嗓音嘶哑程度的自动测试与处理系统．该系统具有多路生理信号检测，电声门图参数提取，诣波噪声比分析，扰动分析，频谱分析，语话图分析等多种信息处理功能．实验与临床使用结果表明，本系统在正常与病变发声检查、艺术嗓音测试等方面具有重要应用价值． |
| 英文摘要: |
| Presented is a voice auto-testing and processing system, which can reflect the property of vocal cords vibration and the degree of voice hoarseness, uninvasively, dire ctly objectively and quatitatively. The system possesses various signal processing functions such asdetection of multi-channel physiological signal, extraction of chara cteristic parameters of an EGG signal, analyses of harmonics-tonoice ratio, perturba tion, spectrum and spectrogram, and others. Results of experiments and clinical uses show that the present system has important practical value in the testing of normal and pathologica1 speeches and of artistic voice. |
