This study considers language dominance as a composite of proficiency, use, and input, and examines how these constructs in Spanish influence heritage speakers' production of Spanish alveolar taps. Two aspects of Spanish tap production were examined: lingual constriction rates and the degree of lingual constriction. Multiple measures associated with Spanish proficiency, use, and input were reduced to a smaller number of dimensions using principal component analysis, and the effects of the components on heritage speakers' tap production were analyzed using mixed effects modeling. The overall findings suggest that dominance in Spanish may not have an effect on the degree of lingual constriction of heritage speakers' taps, but it does have an effect on how frequently heritage speakers produce taps with lingual constriction. Spanish use and input were found to be the main contributors to heritage speakers' target-like production of taps.
本研究将语言优势视为熟练度、使用和输入的综合，并考察了这些西班牙语结构如何影响西班牙语母语者对西班牙语齿龈塞音的产生。研究考察了西班牙语塞音产生的两个方面：舌部收缩率和舌部收缩程度。使用主成分分析将与西班牙语熟练度、使用和输入相关的多个测量值简化为少数几个维度，并使用混合效应模型分析了这些成分对西班牙语母语者塞音产生的影响。总体研究结果表明，西班牙语优势可能不会影响西班牙语母语者塞音的舌部收缩程度，但会影响西班牙语母语者产生带舌部收缩的塞音的频率。西班牙语的使用和输入被认为是西班牙语母语者产生塞音时达到接近目标的主要因素。
