Learning to speak a foreign language as an adult can be hard as it involves learning new speech sounds and motor commands. In a speech learning environment, feedback from our own speech allows us to monitor and correct ourselves. This project addresses the role of feedback-based speech monitoring in speech learning. Although feedback provides a mechanism to adapt our behaviour, no research to date has directly investigated the relationship between speech learning and feedback. We will investigate this link using behavioural and electrophysiological measures that capture individual variability in speech learning and changes to the brains speech production systems.
