Brazilian Portuguese speech data from three monolingual children aged 1;4 to 3;5, focusing on the acquisition of pre-tonic vowels. The dataset is derived from a study analyzing the order of vowel acquisition in relation to stressed vowels and phonological instability. The data was authored by Bohn Graziela Pigatto and relates to the paulista dialect.
Use Cases
- Modeling the order of vowel acquisition based on the described contrast between high and mid pre-tonic vowels.
- Analyzing phonological instability in pre-tonic positions as described in the study.
- Testing theories like Contrastive Hierarchy Theory or the Principle of Maximum Contrast using child speech data.
- Comparing the acquisition timeline of pre-tonic /e/ and /o/ as highlighted in the results.
Strengths
- Data is focused on a specific linguistic phenomenon (pre-tonic vowel acquisition) within a defined dialect (paulista).
- Study includes longitudinal data from three children across a defined age range (1;4 to 3;5).
- Analysis is grounded in established linguistic theories and prior research cited in the description.
Limitations
- Row count and dataset size are unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Last update date is unknown; freshness unverified.
