Berry)Computes and compares multiple measures of separation and overlap between phonological categories (for example vowels or consonants) in arbitrary multi-dimensional acoustic spaces such as formant values, mel-frequency cepstral coefficients (MFCCs), duration, or learned embeddings. The main entry point, phontrast(), reports several contrast metrics in one call -- Jensen-Shannon divergence and distance (Lin, 1991) <doi:10.1109/18.61115>, the Pillai-Bartlett trace, Bhattacharyya distance and affinity, Mahalanobis distance, and proportional overlap -- globally or by group on a common separation-oriented scale, with bootstrap confidence intervals. rank_contrasts() implements a measurement protocol for ranking speakers' contrasts by Jensen-Shannon distance and checking the ranking against Pillai, with sample-size licensing and a bandwidth-sensitivity check. Also provides utilities for preparing estimates for downstream modelling such as generalized additive models and mixed-effects models. Formerly released as 'phonJSD'.https://github.com/r-universe/berrygrant/actions/runs/37755531811Thu, 08 Oct 2026 02:45:16 GMTphontrast2.5.1successhttps://berrygrant.r-universe.devhttps://github.com/berrygrant/phontrastmultidimensional-workflows.Rmdmultidimensional-workflows.htmlMultidimensional workflows2026-06-26 14:14:172026-07-21 19:26:46quick-start.Rmdquick-start.htmlQuick start: from vowel table to metrics and plots2026-06-26 14:14:172026-07-21 19:26:46jasa-protocol.Rmdjasa-protocol.htmlRanking speakers by Jensen-Shannon distance and checking Pillai agreement2026-10-06 13:44:042026-10-07 22:43:46
