舌缺损严重影响语音功能，本实验中开发了语音分析ＬＰＣＦＦＴ计算机软件，对患者术后的发音情况给予客观评价，技术指标为：元音ＬＰＣ共振峰测定，辅音ＦＦＴ谱线观察，手术前后元音及辅音离散度分析等。结果发现舌部手术以后，在［ａ］、［ｉ］、［ｕ］３个元音中以［ｉ］音的变化较明显，元音［ｉ］的语音指标能较好地反映舌部的功能状态。我们还进行耳听语音测定，并与频谱检查结果之间进行相关分析，结果元音［ｉ］的离散度与耳测评分之间相关性好。
The tongue defect seriously affected the speech function. In this experiment, the speech analysis LPCFFT computer software was developed to objectively evaluate the patient's postoperative pronunciation. The technical indicators are: vowel LPC formant determination, consonant FFT spectrum observation, vowel before and after surgery And consonant dispersion analysis. The results showed that the changes of [i] in the three vowels [a], [i] and [u] were more obvious after the operation of the tongue. The vowel of the vowel [i] Function status. We also performed ear-to-ear phonetics and performed correlation analysis with the results of spectral examinations. As a result, there was a good correlation between the dispersion of the vowel [i] and the ear test score.
