Tools for Tidy Vowel Normalization R package tidynorm version 0.4.1 An implementation of tidy speaker vowel normalization. This includes generic functions for defining new normalization methods for points, formant tracks, and Discrete Cosine Transform coefficients, as well as convenience functions implementing established normalization methods.
