This site contains computational and learning tools for phonologists.
Derive!
Derive! is a tool that facilitates understanding of rule derivation. The user can specify inputs and write a sequence of rules. Then the tool provides derivations, while showing each rule application separately.
Featurize!
Featurize! finds natural classes of segments given a set of features. The set of features is fully customizable.
Naturalize!
Naturalize! is a simplifed version of Featurize!, and will find natural classes of segments given a default set of phonological properties rather than features.
Analyze!
Analyze! is a tool to analyze phonological patterns. The tool calculates the over- or underrepresentation of all sounds at all distances in a list of words. The user can also specify features.
Gibber!
Gibber! is a constraint-based Maximum Entropy phonotactic learner which infers a probability distribution on phonological strings. Based on the work of Hayes and Wilson.
