Research on next-generation speech enhancement for auditory barrier-free between elderly and younger persons

介绍了一种针对老年人和年轻人之间听觉无障碍的语音增强技术。在第一项研究中，研究了与听觉印象相关的声学特征。然后提出了基于特征的图像增强技术，并对该技术进行了评价。实验结果表明，该技术能有效地改善听觉效果。此外，还提出了针对非典型语音（如喊叫、嘶哑）的语音分析方法和针对含噪语音的噪声抑制方法。对这些方法进行了评价，并证明了它们的有效性。

A speech enhancement technology for auditory barrier-free between elderly and younger persons was introduced. In the first study, an acoustic feature associated with the auditory impression was investigated. Then, the enhancement technology based on the feature was proposed and evaluated. The results suggested that the proposed technology was effective to improve the auditory impression. Furthermore, speech analysis methods for atypical speech such as shout and hoarse speech and noise suppression methods for noisy speech were also proposed. Evaluations for these methods were carried out, and their effectiveness was demonstrated.
