Abstract
Acoustic characteristics of patients after tongue and mouth floor resection were investigated using computerized maximum likelihood spectrum estimation and compared with normal subjects. The following resuIts were obtained: 1) F1 was located at a higher frequency in glossectomee than that in normal subjects. 2) In the 2 to 3 kHz range, features of spectrum peaks in glossectomee showed various abnormal patterns, which were not observed in normal subjects. 3) In the 2 to 3 kHz range, variations in the spectral peak with time were observed in glossectomee, which were not observed in normal subjects. From these results it is suggested that the selection of the analysis method is very important for observing the acoustic features of glossectomee.
