Motor Speech Disorders in Idiopathic Speech Delay and in Complex Neurodevelopmental Disorders using the Speech Disorders Classification System: Introduction

Purpose The goal of this article (PM I) is to describe the rationale for and development of the Pause Marker (PM), a single-sign diagnostic marker proposed to discriminate early or persistent childhood apraxia of speech from speech delay. Method The authors describe and prioritize 7 criteria with which to evaluate the research and clinical utility of a diagnostic marker for childhood apraxia of speech, including evaluation of the present proposal. An overview is given of the Speech Disorders Classification System, including extensions completed in the same approximately 3-year period in which the PM was developed. Results The finalized Speech Disorders Classification System includes a nosology and cross-classification procedures for childhood and persistent speech disorders and motor speech disorders (Shriberg, Strand, & Mabie, 2017). A PM is developed that provides procedural and scoring information, and citations to papers and technical reports that include audio exemplars of the PM and reference data used to standardize PM scores are provided. Conclusions The PM described here is an acoustic-aided perceptual sign that quantifies one aspect of speech precision in the linguistic domain of phrasing. This diagnostic marker can be used to discriminate early or persistent childhood apraxia of speech from speech delay.

Primary Problem

Twenty-five "experts" on neurogenic motor speech disorders participated in a tutorial exercise. Each was given information on M, a patient who had communication difficulties as the result of stroke, and asked to complete a questionnaire about his problem. The information included a detailed case description, an audiotape of M's speech obtained at 4, 9, 13, and 17 days post-stroke, and test results from the Western Aphasia Battery, the Token Test, and a battery for apraxia of speech. The experts were in excellent agreement on M's primary problem, although it was called by seven different names. The experts were in poor agreement on his secondary problem(s), e.g., the presence and type of aphasia and dysarthria. The results suggest that labeling is difficult, even for "experts." Furthermore, the practicing clinician needs to be sensitive to the likelihood of more than one coexisting problem.
