In acoustic analysis, there were no significant changes in F0, jitter, shimmer, NHR, VTI, SPI. But vAM was statistically increased. Vowels and nasal consonants formant frequency analysis results in patients showed no statistically correlation in 1months after tonsillectomy. Although the statistically increased in the nasal consonants.CONCLUSIONS:
Although the temporary increase or decrease in the acoustic factor or formant in the vowels and nasal consonants after tonsillectomy, but most factors are make no difference.
