Replication Data for: L'acquisition des voyelles nasales en français : une étude acoustique et perceptive sur la prononciation des apprenants néerlandophones belges

<b> Dataset abstract </b>
<p>This dataset contains two types of data on the production accuracy of French nasal vowels realized by L1 Belgian Dutch learners, i.e. listener-based and acoustic measures. By focusing on these two measures, we shed light on two different dimensions of production accuracy, i.e. vowel intelligibility and phonetic nativelikeness. First, this dataset contains acoustic data of 20 L1 Belgian Dutch speakers and 12 L1 Northern Metropolitan French speakers (Carignan, 2014). Vowels were produced in high-frequency monosyllabic French words during a reading task. F1 and F2 values were calculated for the midpoint of each vowel and normalized using Lobanov z-score calculation both across and within speaker groups. Secondly, this dataset contains perceptual data of 71 L1 French speakers respectively representing the Ile-de-France region (France) and Liège (Belgium). Participants performed an online identification task that assessed both listeners’ actual understanding of non-native accented nasal vowels and their category goodness judgments on a 5-point scale (1 = "bad", 5 = "good").</p>
