摘要

语音清晰度指数(SII)和语音传输指数(STI)是公认的评估语音清晰度的客观指标。在以往的工作中,人们研究了 STI 与中文语音清晰度(CSI)得分之间的关系。本文在不同的背景噪声水平(40dBA 和 55dBA)和不同的混响时间下,采用听觉化方法研究了 60-69 岁和 70 岁以上老年人房间中 SII 和 CSI 分数之间的关系。结果表明,SII 与老年人的 CSI 分数具有良好的相关性。要获得与青壮年相同的 CSI 分数,老年人需要更大的 SII 值,而且该值随着老年人年龄的增加而增加。由于在计算 SII 时考虑了老年人的听力损失,因此在 CSI 分数相同的条件下,老年人和年轻人所需的 SII 差异小于所需的 STI 差异。这表明,SII 对不同年龄的人来说是一个更加一致的评价标准。

Chinese speech intelligibility and speech intelligibility index for the elderly

The speech intelligibility index (SII) and speech transmission index (STI) are widely accepted objective metrics for assessing speech intelligibility. In previous work, the relationship between STI and Chinese speech intelligibility (CSI) scores was studied. In this paper, the relationship between SII and CSI scores in rooms for the elderly aged 60–69 and over 70 is investigated by using auralization method under different background noise levels (40dBA and 55dBA) and different reverberation times. The results show that SII has good correlation with CSI score of the elderly. To get the same CSI score as the young adults, the elderly need a larger SII value, and the value increases with the increase of the age for the elderly. Since hearing loss of the elderly is considered in the calculation of SII, the difference in the required SII between the elderly and young is less than that of the required STI under the same CSI score condition. This indicates that SII is a more consistent evaluation criterion for different ages.
