Enhanced Delta Band Neural Tracking of Degraded Fundamental Frequency Speech in Noisy Environments.

Pitch variation of the fundamental frequency (F0) is critical to speech understanding, especially in noisy environments. Degrading the F0 contour reduces behaviorally measured speech intelligibility, posing greater challenges for tonal languages like Mandarin Chinese where the F0 pattern determines semantic meaning. However, neural tracking of Mandarin speech with degraded F0 information in noisy environments remains unclear.

No Musician Advantage in the Perception of Degraded-Fundamental Frequency Speech in Noisy Environments.

Purpose: Pitch variations of the fundamental frequency () contour contribute to speech perception in noisy environments, but whether musicians confer an advantage in speech in noise (SIN) with altered information remains unclear. This study investigated the effects of different levels of degraded contour (i.e.
