Priming from previously heard clear speech can boost intelligibility of degraded speech

Evidence

Deficits in auditory perceptual abilities have a direct consequence for perception of sounds in natural environments. Audibility is the greatest factor in communication difficulties for listeners with hearing loss. However, supra-threshold deficits all contribute to poor auditory perception. … Specific deficits can be difficult to compensate for using modern hearing aid technology, and in many cases, hearing aid algorithms distort the cues available to a listener with SNHL. Despite the distortion provided by these algorithms, hearing aids provide benefits to speech understanding. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1777 (#complicates, via linked claim)
