Processes of phonological change in developmental speech disorders

Area of Science:

• Speech-Language Pathology
• Developmental Pediatrics
• Linguistics

Background:

• Developmental speech disorders affect phonological processes.
• Accurate assessment of phonological change is crucial for effective intervention.
• Existing analytical methods may not fully capture the nuances of phonological development in disordered speech.

Purpose of the Study:

• To present two novel analytical frameworks for identifying and measuring phonological change.
• To provide clinicians with tools to guide treatment planning for children with developmental speech disorders.
• To evaluate the utility of these frameworks using longitudinal data.

Main Methods:

• Description of two distinct analytical frameworks.
• Application and evaluation of frameworks on longitudinal speech data from children with developmental speech disorders.
• Qualitative and quantitative analysis of phonological processes.

Main Results:

• The frameworks successfully identified and measured key phonological changes.
• Longitudinal data analysis demonstrated the frameworks' ability to track developmental trajectories.
• The frameworks offer a structured approach to understanding phonological development in this population.

Conclusions:

• The proposed analytical frameworks are effective for assessing phonological change in children with developmental speech disorders.
• These frameworks can inform and enhance clinical decision-making in speech therapy.
• Further research should explore the broader applicability of these frameworks across different speech sound disorders.
