Abstract:
In order to understand the vibration regularity and morphologic alteration of vocal folds objectively and directly without invading and disturbing the normal pronunciation, the voice acoustic multilateral analysis was conducted and electroglottograph was defecated for 59 cases of normal voice and 102 cases (136 times) of pathological voice by Dr. Speech software through computer' s multimedia technique. The results showed that except F0 there was no sexual difference in the parameters such as jitter, shimmer, NNE and SDF0; there was obvious difference in the parameters between normal and pathological voice. There was a falling tendency for the parameters between preoperation and postoperation. The Egg curve's variation can well reflect the morphologic alteration of vocal folds in voice diseases, and the abnormal ratio is 83.7 % and obvious lower in postoperation reexamined cases.
