When Bed Goes Bad: How the Brain Can Fix Mistakes in Speech While They Happen

WHEN WE TALK, WHO IS LISTENING? We did an experiment to figure out what happens when we hear ourselves make a slip of the tongue – we will call it a speech error. The participants in our experiment talked through a microphone and wore headphones, which we used to play back what they said while they were talking (there was almost no delay, so they heard each word through the headphones at the same time as they said it). Our goal was to scan the brains of these participants in two conditions: when they spoke correctly, and when the words did not sound right.
