Table 2_A methodological protocol for multimodal profiling of conversational abilities in

A protocol for a cross-sectional observational study of 180 Mandarin-speaking children aged 4-6, developed by Cai Wang. The study aims to evaluate a culturally adapted framework for profiling conversational abilities in children with and without Developmental Language Disorder, using audio-video recordings and linguistic annotation. The protocol was last updated in May 2026.

Use Cases

• Developing automated annotation pipelines for conversational features based on the described CHAT/ELAN transcription and annotation tiers.
• Training models to classify communicative acts or gesture-speech alignment based on the INCA-A coding scheme mentioned in the methods.
• Analyzing correlations between demographic factors and language outcomes based on the described exploratory analyses of home-environment moderators.
• Benchmarking the feasibility of multimodal data collection in clinical linguistics based on the explicit session completion and reliability metrics.

Strengths

• Protocol is designed for a specific sample of 180 children (90 with DLD, 90 typically developing).
• Includes explicit feasibility benchmarks for session completion, recording length, and utterance yield.
• Employs a detailed multimodal annotation framework covering utterance features, communicative acts, repairs, turn-taking, and gesture-speech alignment.
• Released under a permissive CC-BY-4.0 license for reuse and adaptation.

Limitations

• The dataset is a 19.1 KB DOCX protocol document, not the underlying observational data itself.
• Row count and column-level documentation for any potential accompanying data are unknown.
• The cross-sectional design, noted as a limitation in the description, prevents analysis of longitudinal development.
