PhonBank

PhonBank aggregates longitudinal child phonological corpora within the TalkBank system to support analysis of phonological development and disorders.

Key Features:

• Data Repository: Contains longitudinal phonological data from typically-developing children and children with phonological disorders across multiple languages, including English, French, German, and Portuguese.
• Analytical Software Integration: Integrates the Phon software program to build and analyze textual and phonological data corpora and to support systematic analysis of consonants in phonetic contexts such as singleton onsets, codas, and onset clusters.

Scientific Applications:

• Complexity-based analysis: Enables empirical evaluation of the complexity approach to speech disorders, including the role of phonological markedness in acquisition.
• Implicational relationship investigation: Supports analysis of implicational relationships among phonological units within and across languages to constrain generalizations about markedness.
• Developmental and clinical research: Facilitates study of typical and atypical phonological development using longitudinal corpus data.

Methodology:

Systematic analysis of longitudinal phonological data using the Phon program to build and analyze textual and phonological corpora and to identify patterns among phonetic units, including analyses of consonants in singleton onsets, codas, and onset clusters.
