Articulation error migration: a comparison of single word and connected speech samples

In this study frequency and type of articulation error, including error migration, were compared between single word production and connected speech samples when vocabulary was held constant. Spontaneous single word and connected speech samples were obtained from 20 articulation disordered children ages 5-4 to 12-8 years. There were significantly more errors in connected speech samples than single word utterances. The difference between samples, i.e., error migration, is discussed, as is the predictive value for speech-language clinicians.
