Description This study is designed to investigate the effects of Sound Production Treatment (SPT; a treatment for acquired apraxia of speech) on sound production accuracy in persons with chronic apraxia of speech (AOS). Organization of practice (blocked practice or randomized practice) will be manipulated in an effort to determine the most efficacious application of SPT. A combination of group and single-subject experimental designs will be completed with 24 speakers with AOS (2 groups of 12 participants).
