Table 4.

Descriptive Statistics (mean(SD)) for Consonant Productions in video and audio recordings overall, and by VMS group. Tokens refer to individual CPs, types refer to distinct consonants. Columns 4 and 5 show mean(SD) for proportion of congruent tokens in the videos for the two context variables (group n in column header; one infant was not included in the Attended Object match data due to having 0 attended objects in their video recording.)

	Group	Audio	Video	Caregiver prompt match (n=44)	Attended object match (n=43)
CP tokens	All	96.6(117)	43.55(34.13)	.48(.23)	.38(.27)
CP tokens	with-VMS	194.29(126.21)	60.13(34.59)	.55(.17)	.49(.27)
CP tokens	no-VMS	27.15(34.14)	23.65(20.59)	.41(.28)	.25(.22)
CP types	All	3.18(1.42)	4.34(1.27)
CP types	with-VMS	4(.88)	4.67(1.31)
CP types	no-VMS	2.2(1.32)	3.95(1.15)
