Speech segments and sustained vowel emissions from 47 individuals (11 cisgender women-CW, 11 transgender women-TW, 11 cisgender men-CM, seven transgender men-TM, and seven non-binary individuals-NB) were recorded, and 14 acoustic measures of noise, perturbation, spectral, and cepstral parameters were extracted.
