Fundamental frequency differences between voices improve speech intelligibility
Evidence
Brokx and Nooteboom (1982) demonstrated that speech intelligibility for sentences improves with an increasing f0 difference between speech and a speech interferer. These benefits generalize to benefits from perceiving speech from different talkers, and are particularly beneficial at low signal-to-noise ratios (SNRs). — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1313
