Six trained observers rated children's /r/ articulation adequacy in repeated sentence contexts live and from audio-recordings. Inter-judge reliability was unaffected by mode of stimulus presentation. However, correct/incorrect values assigned to responses were systematically lower in the recorded analysis. This effect was greater for unstressed vocalic /r/ than for consonantal /r/. Results are discussed with reference to effects of analysis derived from audio-recordings upon studies of allophonic differentiation of /r/ misarticulation in children.
