Table 3.
HSV measures taken from two DKGs representing middle and posterior tissue motion during chest and falsetto registers. Average (mean) and standard deviation (SD) are obtained from 25 to 50 ms HSV samples for each case. The chest register in vowel ∕i∕ exhibits the largest SDs with respect to the mean values for all measures.
