研究韩国语会话语音和清晰语音的声学差异，并利用长期平均语音频谱（LTASS）评价性别对语音清晰度的影响。每个受试者的声音都是用连接到GoldWave程序的声级计记录的。使用MATLAB程序，在归一化到70 dB总水平后，计算从100到10，000 Hz的三分之一倍频程频带语音频谱的平均长期均方根（RMS）。20名普通韩国人与20名韩国播音员进行了比较，每组男女人数相等。与普通男性相比，普通女性的LTASS在低频时较低，但在630、800、1,600、5,000和10,000 Hz时较高。与男播音员相比，女播音员的LTASS在低频时更低。男播音员在100、125、200和250 Hz时的LTASS显著低于普通男性。在100、125、160、200、250、500和10,000 Hz时，女播音员的LTASS低于普通女性。播音员的LTASS在100、200 Hz时水平较低，在500、630、800和1,000 Hz时水平较高。本研究显示，在低频率区域，LTASS的下降可能会使女性和播音员的评分分别比男性和普通人更明显。低频的这种下降可能会导致掩蔽的向上传播更少，语音更清晰。这项研究减少了一个错误造成的清晰的语音策略和可懂度增益的广泛变化，因为这项研究招募专业扬声器。我们希望我们的研究结果表明普通韩国人的语音声学特性的差异。
To investigate acoustic differences between conversational and clear speech of Korean and to evaluate the influence of the gender on the speech clarity using the long-term average speech spectrum (LTASS). Each subject's voice was recorded using a sound level meter connected to GoldWave program. Average long-term root mean square (RMS) of one-third octave bands speech spectrum was calculated from 100 to 10,000 Hz after normalizing to 70 dB overall level using the MATLAB program. Twenty ordinary Korean were compared with 20 Korean announcers with equal numbers of men and women in each group. Compared with the LTASS of ordinary men, that of ordinary women was lower at low frequencies, but higher at 630, 800, 1,600, 5,000, and 10,000 Hz. Compared with the LTASS of male announcers, that of female announcers was lower at low frequencies. Compared with the LTASS of ordinary men, that of male announcers was significantly lower at 100, 125, 200, and 250 Hz. Compared with the LTASS of ordinary women, that of female announcers was lower at 100, 125, 160, 200, 250, 500, and 10,000 Hz. The LTASS of announcer showed lower levels at 100, 200 Hz and higher at 500, 630, 800, and 1,000 Hz that that of ordinary Koreans. This study showed that the drop-off of the LTASS in the low frequency region might make the ratings of women and announcers more clearly than those of men and ordinary persons respectively. This drop-off in the low frequency might result in less upward spread of masking and clearer speech. This study reduced an error resulting from a wide variability of clear speech strategies and intelligibility gains, because this study recruited professional speakers. We hope that our results demonstrate the difference in acoustic characteristics of the speech of ordinary Korean persons.
