Using competing speech to estimate articulatory automatization in children: the possible effect of masking level and...

In order to study the possible influence of masking level and subject grade on a procedure for determining a child's articulatory automatization (Manning et al., 1976) 47 first and second grade and 49 third and fourth grade children were administered the McDonald Deep Test of Articulation under one of five conditions of auditory masking (earphones only, or presentation of competing speech at 50, 60, 70, or 80 dB SPL). Results indicated no significant difference in subject performance across the factors of masking level and subject grade. The findings suggest that these factors do not appear to be critical in the clinical application of the suggested procedure for estimating children's automatization of newly acquired phonemes.
