Articulatory variability is reduced for people with flatter palates [Bakst and Lin (2015). Proceedings of the 18th International Congress of Phonetic Sciences; Brunner, Fuchs, and Perrier (2009). J. Acoust. Soc. Am. 125(6), 3936-3949]. Brunner, Fuchs, and Perrier [(2009). J. Acoust. Soc. Am. 125(6), 3936-3949] hypothesized that this is because the mapping between articulation and acoustics depends on palate depth. Articulatory synthesis was used with three different palate shapes to generate productions of /r/. The parameter spaces of the articulatory synthesizers were searched for vocal tract configurations that result in low F3 (the hallmark acoustic cue for /r/). Palate shape influences not only the sensitivity of the articulatory-acoustic mapping, but also the effect of each individual articulatory parameter on F3.
构音变化的可变性对于腭部较平的人来说较小[Bakst 和 Lin（2015）。第 18 届国际语音科学大会论文集；Brunner、Fuchs 和 Perrier（2009）。J. Acoust. Soc. Am. 125(6), 3936-3949]。Brunner、Fuchs 和 Perrier [(2009). J. Acoust. Soc. Am. 125(6), 3936-3949]假设这是因为发音和声学之间的映射取决于腭部深度。使用三种不同的腭形状进行发音合成，以生成/r/的发音。在发音合成器的参数空间中搜索导致 F3 较低的声道配置（/r/的标志性声学线索）。腭形状不仅影响发音-声学映射的灵敏度，还影响每个单独的发音参数对 F3 的影响。
