It has been suggested that the larger area of the average female acoustic vowel space is a consequence of compensating for poorer harmonic sampling of the spectral envelope resulting from a higher f0. This predicts that there should be variation in vowel space size within any group of males or females representing sufficient interindividual range of average f0. Inspired by this, the present paper examines whether there is a correlation between a speaker's f0 and the size of the speaker's F2xF1 vowel space. A highly significant correlation between f0 and vowel space size is found in the female group of a sample of 87 German students. However, no such correlation is found between f0 and the Euclidean distance between same speaker tokens of /e:/ and /a:/.
