TL;DR: Examples of research using the extensions to the SDCS described in the present report include diagnostic findings for a sample of youth with motor speech disorders associated with galactosemia, and a test of the hypothesis of apraxia of speech in a group of children with autism spectrum disorders.

TL;DR: The Pause Marker is an acoustic-aided perceptual sign that quantifies one aspect of speech precision in the linguistic domain of phrasing that can be used to discriminate early or persistent childhood apraxia of speech from speech delay.

TL;DR: In this article, a companion paper describes three extensions to a classification system for paediatric speech sound disorders termed the Speech Disorders Classification System (SDCS), which uses perceptual and acoustic data reduction methods to obtain information on a speaker's speech, prosody, and voice.

TL;DR: Findings are interpreted as providing support for the PM as a near-conclusive diagnostic marker of childhood apraxia of speech (CAS).

TL;DR: Results support the hypotheses of core representational and transcoding speech processing deficits in CAS and theoretical coherence of the PM's pause-speech elements with these deficits.
