Connecting Preschoolers' Spontaneous Speech Patterns to Future Language Skills: A 3-Year Concurrent and Longitudinal Cohort Study of Canonical Proportion as a Developmental Index.
Article in Journal of speech, language, and hearing research : JSLHR, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeUnderstanding how children's spontaneous language behavior relates to standardized metrics of speech and language remains a crucial challenge in studies of language acquisition and clinical assessment. Traditional lab- and clinic-based paradigms are time- and resource-intensive and may not fully capture a child's underlying language competencies. This study aimed to investigate whether automated analysis of naturalistic, child-centered audio recordings can index the developmental trajectory of speech-language abilities from 2 to 5 years of age.
methodA longitudinal design was employed with
resultsCanonical proportion measures significantly predicted multiple dimensions of later speech-language development. The strongest longitudinal associations were observed for consonant articulation skill and vocabulary size. Weaker, although still significant, relationships were found for metaphonological skills, including phonological awareness and phonological working memory.
conclusionsFindings suggest that children's spontaneous, everyday speech production patterns provide moderate indices of subsequent language development across multiple domains. Automated measures such as canonical proportion hold promise for expanding and diversifying approaches to studying language acquisition and for complementing traditional lab-based assessments.
