TABLE III.

Differences in parameter values between the F0-based segregation algorithm of Meddis and Hewitt (1992) for concurrent vowel identification and the current implementation, both of which were based on a population of AN-fiber ACFs.

Parameters	Meddis and Hewitt (1992)	Current implementation
ACF time constant (ms)	10	20
Vowel segregation criterion: maximum percentage of channel ACFs with dominant pitch	80	75
Single- versus double-vowel criterion in no-segregation case: Ratio of template matches (m1/m2)	0.5	0.07
