This is a Julia package that calculates various lexical characteristics for experiments in phonetics and psycholinguistics. Currently, the package will calculate phonological neighborhood density, uniqueness point, and phonotactic probability. It also provides access to the vantage point tree used in the calculation of the phonological neighborhood density, for use in other tasks that require a vantage point tree. This vantage point tree implementation has only been tested to work for text data, and specifically for calculating the phonological neighborhood density, however.
More information on each of these characteristics, as well as usage examples may be found in their respective pages in this documentation.
