Acquired apraxia of speech (AOS) is a relatively common motor speech impairment caused by left-hemisphere pathology. Despite its presumed prevalence, the differential diagnosis of AOS remains one of the most challenging in speech-language pathology. Diagnosis of individual clients can be surprisingly unreliable from one diagnostician to another. A major reason for the low reliability is that clinicians must interpret and integrate many diverse speech features without the benefit of quantitative criteria. The purpose of this course is to define contemporary criteria for AOS in practical and observable terms. A variety of measurement options are illustrated and applied to clinical decision-making.

1. Diagnosing Apraxia of Speech (AOS)

This chapter begins with conceptual and behavioral definitions of AOS. Because diagnostic criteria have evolved over the years, it is important that clinicians use the same frame of reference.

2. Evaluating Articulatory Criteria

The most functional consequence of AOS is impaired ability to articulate what one intends. Some difficulties with sound production give information about severity, others about diagnosis. In this chapter, both types are reviewed, and measurement techniques are illustrated.

3. Evaluating Prosodic Criteria

The purpose of Chapter 3 is to define aspects of speech rate and prosody that are relevant to AOS and to identify strategies for quantifying them. This dimension is particularly influential for differential diagnosis.

4. Interpretation

The purpose of Chapter 4 is to explain how to interpret the measurements discussed in Chapters 2 and 3. Because clinical samples include heterogeneous presentations, diverse profiles are considered.
