The present experiment investigated the effect of word length on the length of f0 intervals for North Kyungsang children. In order to find out the lengths of the f0 intervals, the f0 values at the midpoints of vowels in words were measured. F0estimates were computed as intervals consistent with the logarithmic scale corresponding to the number of syllables in thewords. The results indicated that the mean f0 intervals in words of different lengths showed a significant difference for theHH in HH vs. HHL and the LH in LH vs. LLH for North Kyungsang children. Adult speakers from the North Kyungsangregion significantly differed only within the HH in HH vs. HHL. Adult speakers made a noticeable contribution in thischaracteristic from the children. The result of the adult study was presented to confirm whether the children used a NorthKyungsang dialect. With respect to individual speaker differences, the North Kyungsang children showed more or lessconsistent patterns in quantile-quantile plots for the HH vs. HHL, but for the HL vs. LHL and LH vs. LLH, there were morevariations than for the HH vs. HHL. The individual speakers’ variation was the largest for the HL vs. LHL and the smallestfor HH vs. HHL. Considering these results, the effect of word length on f0 intervals tended to show pitchaccent-type-specific characteristics in the process of prosodic acquisition.
