目的：观察连续用力吹气练习(SFBE)对正常人发音的即时影响。方法43名健康成年人在SFBE前后分别进行3次最长时间的发/a/音，对录音文件进行声音参数分析，包括平均最长发声时间(MMPT)、发声平均频率(MF)和平均声级(MSPL)。结果 SFBE后，被试MMPT (P<0.01)和MSPL (P<0.001)明显提高，MF无显著性差异(P>0.05)。结论 SFBE可以提高健康成年人MMPT和MSPL，对MF无明显影响。

Objective To observe the immediate effects of the sustained forced-blowing exercise (SFBE) on the phonation function in young healthy people. Methods 43 young healthy people were asked to pronounce a longest/a/in a comfortable situation within one breath for 3 times before and after SFBE. The sound files were analyzed with computer sound analysis system, with the parameters of mean maxi-mum phonation time (MMPT), mean frequency (MF) and mean sound pressure level (MSPL). Results The MMPT and MSPL increased (P<0.01) after SFBE. There was no significant difference in the MF (P>0.05) before and after SFBE. Conclusion The SFBE can improve the MPT and MSPL of the healthy people obviously, without affections on the MF.
