ObjectiveTo evaluate the feasibility of using the acoustic change complex (ACC) as an objective cortical marker of continuous speech sound discrimination using connected Ling-six stimuli.DesignCortical auditory evoked potentials were recorded from 10 young adults with normal hearing using a continuous, pause-free sequence of the six Ling phonemes (/u-a-i-ʃ-s-m/). ACC responses were recorded in a passive listening paradigm with minimal electrodes. Reproducibility was assessed in a subset of parti
