Table 4 Recognition rate of test items of 1 to N with N = 5 to N = 200 most frequent syllables

Number of most frequent syllables	Recognition rate in % without frequency correction	Recognition rate in % with frequency correction
5	100,0	100,0
10	97,2	97,4
20	91,1	93,2
50	90,2	92,7
100	88,9	92,3
200	85,8	91,8

The recognition rate without frequency correction (second column) shows the mean recognition rates for all N syllables, each syllable weighted equally. The frequency correction (third column) shows recognition rates for all N syllables, now weighted with respect to the frequency of occurrence of each syllable within the corpus (i.e. highly frequent syllables occur more often and also indicate higher recognition rates).
