Delayed Versus Atypical Speech Sound Development: A Markedness-Based Analysis of Speech Sound Disorder in Cantonese

The findings from the current study suggest that the weightage-based Maximum Entropy grammar approach can delineate between the SSD subgroups (i.e., SSD-delay vs. SSD-atypical) defined by the ranking-based traditional OT approach. These findings offer a starting point into the development of objective tools for clinicians for detecting the SSD subgroups to make decisions on treatment type, as we speculate different treatment approaches for SSD-delay versus SSD-atypical subtypes.
