Participants will receive tDCS via a Starstim device at 1mA for 20min of the total three hours of intensive speech therapy time at the beginning of each session. The stimulation will be ramped up for 45 seconds and ramped down for 15 seconds. For the experimental group, the stimulation will be ramped up for 45 seconds and stay there for 20 min. The participants will receive three weeks of tDCS and continue receiving only intensive speech therapy for five weeks for three hours a day.
