A command to create a TableOfReal filled with the first three formant frequency values and (optionally) the levels from the 12 Dutch monophthongal vowels as spoken in /h_t/ context by 25 female speakers.
The first three columns will contain the frequencies in Hz, the next three columns the levels in decibels below the overall SPL of the measured vowel segment. Each row will be labelled with its corresponding vowel symbol.
More details about these data and how they were measured can be found in the paper of Van Nierop et al. (1973).
