The relevance of auditory feedback for consonant production: the case of fricatives

This data set contains the data of 19 native Russian speakers for whom the spectrum of the target fricative [sj] was auditorily perturbed in two opposite directions. The main goal of the study was to investigate whether speakers were able to develop two different compensatory strategies to successfully produce the target sound. In the accompanying R code, we present a multi-parameter analysis where we examine the relevance of a series of acoustic measures for describing the adaptation process. By applying a supervised classification algorithm (Random Forest; RF), we aimed to identify those acoustic parameters which were systematically affected during the adaptation process. Consequently, to break down the adaptation process into individual compensatory strategies, we traced specific acoustic changes that occurred over the course of the experiment by means of generalized additive mixed models (GAMM).本数据集涵盖19名俄语母语者的实验数据，实验中对目标擦音[sj]的频谱施加了两种相反方向的听觉扰动。本研究的核心目标为探究说话者能否习得两种不同的补偿策略，以成功产出目标语音。在配套的R代码中，我们开展了多参数分析，以检验一系列声学测量指标在描述适应过程中的相关性。通过应用监督分类算法——随机森林（Random Forest，RF）——我们旨在识别出适应过程中受到系统性影响的声学参数。据此，为将适应过程拆解为各个独立的补偿策略，我们借助广义加性混合模型（Generalized Additive Mixed Models，GAMM）追踪了实验全程中发生的特定声学变化。
