Understanding speech in noise (SIN) is a highly complex task affected by reciprocal sensory-cognitive interactions in the brain. The auditory brainstem response to complex stimuli (cABR) provides an objective index of the neural transcription of features (e.g. temporal, spectral) that are important for speech understanding. Influenced by cognitive factors such as attention and memory, measures of subcortical processing can further our knowledge of the biological mechanisms associated with deficits in SIN perception in clinical populations, such as children with learning impairments, older adults, and individuals with hearing impairment. Further, subcortical processing is modifiable through long-term experience and short-term training, making cABR a highly reliable probe for delineating the effects of training on neural speech processing.
