(a) Voicing percentage of fricatives in tokens in which the following sonorant
/l/ or /H/ was classified as non-syllabic, pooled across words, repetitions and
speakers. (b) Voicing duration in tokens classified as non-syllabic, pooled
across words, repetitions and speakers. Predicted voiceless fricatives
have either no voicing at all (as part of the 0 to 10 ms interval) or have
a tail of voicing into the fricative that is only rarely longer than 20 ms.
Although tokens with voicing duration values from 0 to 20 ms also occur
among predicted voiced fricatives, many tokens of predicted voiced
fricatives have voicing durations that are much longer.

from 0 to 25%, although it should be noted that voicing percentage among
predicted voiced fricatives is rarely lower than 5%. Furthermore, predicted
voiced fricatives also have many tokens with voicing percentages
