Harrington's team recorded the winterers reciting a list of words before they left for Antarctica.

哈林顿的研究小组记录了这些越冬者出发去南极前朗读单词表的声音。

Then, while there, the winterers recorded themselves saying the same words four more times.

之后，在南极时，越冬者又录了4次他们朗读相同单词的声音。

And even during their short time in Antarctica, the way the winterers produced certain vowels began to converge, averaging out the resonances.

即使在南极短暂的逗留时间，越冬者某些元音的发音方式就开始趋同，将共振频率拉平。

In addition, the winterers invented slightly new ways of pronouncing vowels, such as shifting the production of the second syllable in the word " window" very slightly forward in the vocal tract.

此外，越冬者还发明了略新颖的元音发声法，比如改变单词“window”第二音节的发音，让声道发音位置稍微靠前一些。
