Abstract

When we speak, the parts of our brains responsible for moving and hearing are engaged in a precisely timed dance of coordinated electrical activity. This coordination allows us to monitor our speech for errors without our own sound inputs distracting or confusing us. If we introduce a small delay between when we produce speech and when we hear it, most people will slow down and make speech errors, which suggests how important timing is during speech. Non-invasive brain stimulation using transcranial alternating current stimulation (tACS) provides a safe method to directly alter rhythmic brain activity, but it has not been previously used to understand speech production. In this project, we will establish methods to manipulate the coordinated brain rhythms evoked during speaking using tACS and deploy these methods to modify the effects of delayed auditory feedback on speech output. This work will establish new tools for basic research in speech neuroscience and will catalyze future efforts to understand and modify speech-related brain activity in people with communication disorders.
