Speech production minimally includes a level encoding context-specific articulatory timing patterns (motor plans) and a level with context-independent (phonemic) representations. Impairment to motor planning is associated with AOS whereas phonological impairment is associated with phonemic paraphasia. Each of these frequently co-occurring deficits produces articulatory errors whose loci are difficult to determine.  Using acoustic analysis, we report on two individuals diagnosed with AOS and PP who make similar articulatory errors (/s/-deletion), and identify one individual whose errors reflect deletions after the motor plan is generated, and another whose errors reflect deletion prior to motor planning.
