Voicesauce: A Program for Voice Analysis

VOICESAUCE is a new application, implemented in MATLAB, which provides automated voice measurements over time from audio recordings. The measures currently computed are F0, H1(*), H2(*), H4(*), H1(*)‐H2(*), H2(*)‐H4(*), H1(*)‐A1, H1(*)‐A2, H1(*)‐A3, energy, Cepstral Peak Prominence, F1–F4, and B1–B4, where (*) indicates that harmonic amplitudes are reported with and without corrections for formant frequencies and bandwidths [Iseli et al. (2006)]. Formant values are calculated using the Snack Sound Toolkit, while F0 is calculated using the STRAIGHT algorithm; harmonic spectra magnitudes are computed pitch‐synchronously. VOICESAUCE takes as input a folder of wav files, and for each input wav file produces a MATLAB file with values every millsecond for all measures. It can operate over the whole input file or over segments delimited by a PRAAT textgrid file. VOICESAUCE then takes these MATLAB outputs, optionally along with electroglottographic measurements obtained separately from PCQUIRERX, and provides con...
