Dataset associated with Alamounti et al., 2026, "Visual contributions to the perception of speech in noise".The dataset is saved as an excel datasheet containing raw data from 37 normal hearing participant's whose data was included within this project. Each row represents a run from a single participant, coded by their participant identification number, the SRT50 for that run, the condition tested, and the run number. Note that each "run" was two randomly interleved staircases where one was the target coherent condition and the second was the masker coherent condition. After completion of the vCCRMn thresholds (3 conditions x 3 runs, yielding 18 threshold measurements) participants were assessed for their lip reading ability.
