Abstract:
Objective:To investigate if there is difference about the parameters of acoustic analysis with the different vowe |a|、|i|、| | and decide which vowels is best fitted to the acoustic analysis. Method:40 normal and 130 pathologic voice patients accepted acoustic analysis. Each acoustic parameters such as jitter,shimmer、NNE、 SDF0、SNR were compared with different vowels. Result:Jitter、shimmer、NNE with |i| were much lower than that with |a| and | | in normal cases and light hoarseness group. While the acoustic parameters with |i| were much higher than that with |a| and | | in moderate and heavy hoarseness group. Conclusion: |a| and | | were the preferred vowels for normal and light hoarseness group,while the |i| could supply some useful suggestion for the moderate and heavy hoarse patients.
