Summary
This study developed a speech intelligibility test for children aged 3-7. Sentence structure, not word choice, revealed language development differences in young children.
Area of Science:
- Linguistics
- Developmental Psychology
- Speech-Language Pathology
Background:
- Assessing speech intelligibility in children requires age-appropriate materials.
- Existing tests may not adequately capture developmental variations in language production.
Purpose of the Study:
- To develop and validate sentence structures for a new speech intelligibility test for children aged 3-7 years.
- To identify linguistic markers of language development in children's sentence generation.
Main Methods:
- Children aged 3-7 years generated word and sentence messages.
- Analysis of word and sentence materials based on chronological age, vocabulary, and receptive language skills.
- Development of two sentence constructions to account for developmental differences.
Main Results:
- Word materials showed no significant differences across developmental measures.
- Sentence materials revealed age-related variations in complexity and grammatical structure.
- Younger children used simplified sentence structures (e.g., proforms, omitted auxiliary verbs) compared to older children.
Conclusions:
- Sentence structure is a more sensitive indicator of language development in young children than word choice for intelligibility testing.
- The proposed sentence constructions can help equate for differences in normal language development.
- This research contributes to the creation of more accurate speech intelligibility assessments for pediatric populations.
