Baseline neuroimaging data will be acquired from all participants via MRI, EEG. Each participant will be seen for multiple testing sessions over a five day period. LD participants will undergo the neuromodulation (HD-tDCS Stimulation) for twenty minutes while engaged in watching videos/movies or performing a word production task.
Inclusion Criteria: * Participants must be clinically evaluated for the diagnosis of LD or have the proof of LD diagnosis. (Not applicable for control participants) * No other known or history of speech, voice disorder other than LD. * Provision of signed and dated informed consent form. * Stated willingness to comply with all study procedures and availability for the duration of the study * Must not be pregnant.
