Abstract: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.
Keywords:Eletroglottography  Harmonics-to-noise ratio  Inverse Filtering
