This paper summarized the acoustic characteristics of whispered speech and introduces existing whispered speech corpuses.

该文介绍了耳语音的特点和现有的耳语音语音库。

Other things that impressed me deeply are the underground Jiaohe and Gaocang, the dried ancient corpuses and the underground irrigation canal networks.

我印象深刻，是地下蛟河和Gaocang，干古语料和地下灌溉渠网的其他事项。
