Acoustic and communicative data of voices perceived as neutral, feminine, or masculine

The dataset includes recordings from 47 Brazilian speakers of diverse gender identities (cisgender women, cisgender men, transgender women, transgender men, and non-binary individuals). Perceived gender was judged by 101 cisgender listeners using a 101-point visual analogue scale ranging from “very masculine” (−50) to “very feminine” (+50).

Voices were categorized as feminine, neutral, or masculine using z-scores (±1 SD around the neutral midpoint). The dataset includes 16 acoustic measures extracted from sustained vowels, automatic speech, and expressive reading, using Praat scripts for jitter, shimmer, f₀ measures, HNR, H1–H2, spectral emphasis, CPPS, ABI, AVQI, speech rate, articulation rate, and prosodic variability. Additionally, 28 communicative parameters were evaluated by two experienced speech-language pathologists using the Brazilian protocol RoFOE (Roteiro Fonoaudiológico de Observação da Expressividade), covering aspects such as naturalness, confidence, pleasantness, resonance patterns, articulation precision, fluency, pause patterns, emphasis strategies, and verbal organization.
