This package allows R users to leverage\nPraat's powerful phonetic analysis capabilities directly from\nR. The package exposes 39 Praat modules with 500+ methods for\nsound manipulation, robust formant tracking (FormantPath,\nFormantModeler), speech synthesis (KlattGrid), pitch analysis,\nintensity measurements, spectral analysis (ComplexSpectrogram),\ncepstral coefficients (MFCC, LFCC), statistical analysis (PCA,\nDiscriminant), auditory modeling (Cochleagram, Excitation),\nTextGrid annotation, voice quality assessment, geometric\noperations (Polygon), and a persistent Praat script interpreter\nwith bidirectional R-Praat object transfer.", "License": "GPL-3 + file LICENSE", "URL":
