Fast Screening for Children's Developmental Language Disorders Using a Novel Deep Learning Framework

Executive Summary

This report highlights findings from a groundbreaking study published in the Annals of Translational Medicine (2020) on screening developmental language disorders (DLDs) in children. DLDs affect 5–8% of preschoolers and are linked to conditions like dyslexia and autism. The study introduces a deep learning framework that achieves 92.6% accuracy in DLD screening, addressing challenges like reliance on professional evaluations, incomplete assessments, and failure of text-based tests. Key innovations include:

• Comprehensive Inducing Procedures (CIP): Non-textual, audio-visual stimuli for holistic assessment.
• 13 Linguistic Indicators: Evaluating pronunciation, fluency, grammar, semantics, and logic.
• Benchmark Dataset: 2,200 responses from 284 children.
• Deep Learning Framework: A two-stream encoder and excellent-comparison architecture.

The report details the study's objectives, methodology, results, and implications, emphasizing its potential to revolutionize early DLD diagnosis.

Introduction

Developmental language disorders (DLDs) are the most common developmental disorders in children, impacting 5–8% of preschool-aged children. These disorders affect speech abilities such as pronunciation and comprehension and are associated with broader issues like dyslexia and autism.

Challenges in Traditional Screening

1. Text-Based Stimuli: Ineffective for young, often illiterate children.
2. Incomplete Linguistic Evaluation: Limited indicators lead to gaps in diagnosis.
3. Professional Dependency: Subjective, costly, and time-consuming processes.

The study proposes a fast, automated screening solution using a deep learning framework to overcome these barriers.
