Prevelar raising is the raising of TRAP and DRESS vowels before voiced velars. While BAG-and BEG-raising have been described in Canada, the Upper Midwest, and the Pacific Northwest, an in-depth investigation of their distribution across North America is lacking, especially for BEG. Using an online survey distributed to over 5,000 participants via Reddit (which skews towards younger White males) and ordinary kriging for spatial interpolation, this study finds that prevelar raising is more widespread than previously reported. BAG-raising is found in much of the North and the Upper Midwest. BEG-raising is far more variable and is common across much of the Midlands and the West, with concentrated pockets in the Northern Great Plains and various other regions. This data suggests that the two can occur independently, with areas like the upper Midwest exhibiting BAG-raising alone, and the Midlands and the West reporting BEG-raising alone. These findings suggest that additional research on prevelar raising and other infrequent phonological variables is required to uncover their regional distribution and social meaning.

Prevelar 饲养的区域模式

前置升音是指在浊软颚音之前提高 TRAP 和 DRESS 元音。虽然在加拿大、中西部上游和太平洋西北地区已经描述了 BAG 和 BEG 的提高，但缺乏对其在北美分布的深入调查，尤其是 BEG。这项研究使用通过 Reddit 分发给 5,000 多名参与者的在线调查（偏向于年轻的白人男性）和普通克里金法进行空间插值，发现前胚层升高比以前报道的更普遍。在北部和中西部上游的大部分地区都发现了提袋活动。BEG 的提高变化更大，在中部和西部的大部分地区都很常见，在北部大平原和其他各个地区集中分布。该数据表明两者可以独立发生，中西部上游地区仅展示 BAG 筹集，而中部和西部仅报告 BEG 筹集。这些发现表明，需要对前音升起和其他不常见的语音变量进行额外的研究，以揭示它们的区域分布和社会意义。
