Historically in the United States, in the 1940s, people viewed as " cultured" speakers were more likely to use the " W-H" pronunciation.

从历史上看， 在美国，在 20 世纪 40 年代，被视为“有文化” 的说话者更有可能使用“W-H” 发音。

The " W-H" pronunciations still exist in some regions like Scotland and part of Ireland, and among white speakers in the southern, especially southeastern, United States, with pockets elsewhere.

“W-H” 发音在苏格兰和爱尔兰部分地区等一些地区仍然存在，在美国南部（特别是东南部）的白人使用者中仍然存在，其他地区也存在少数人使用这种发音。

Linguists call this dropping of formerly pronounced H's the " wine-whine merger, " — " wine" W-I-N-E and " whine" W-H-I-N-E — because when people stop pronouncing the H, these two words sound the same.

语言学家把这种去掉原来发音为 H 的词称为“wine-whine 合并”——“wine” 发音为 W-I-N-E， “whine” 发音为 W-H-I-N-E——因为当人们不再发 H 的音时，这两个词的发音就相同了。

It's funny though because some older people are quite vocal that the " W-H" pronunciations like " hwhat" are CORRECT, and there was a smaller subset of highly educated middle-aged people in the study who used the " hwhat" pronunciation.

不过，这很有趣，因为一些老年人非常直言不讳， 认为“W-H” 的发音比如“hwhat”是正确的，而研究中有一小部分受过高等教育的中年人使用“hwhat” 的发音。
