This paper examines the extent to which vowel height data taken from real words differs from data taken from nonsense words, and it finds no significant differences. As a result, it provides quantitative acoustic data for the seven stressed and three unstressed vowels of Standard Catalan (as uttered by female speakers). The data are drawn from three distinct phonetic contexts, i.e., /bVp/, /bVt/, and /bVk/, and the /bVp/ context consists entirely of nonsense words (the other contexts were all real words). A comparison and statistical analysis of the data for each vowel phoneme show that there are neither considerable nor statistically significant differences in the vowel height (F1 values) among the data from the three different phonetic contexts. In terms of vowel height, nonsense words provide as accurate a picrure of the Catalan data as real words do.
