The first is phonological storage, subvocal rehearsal, and the phonological loop. The role of subvocal rehearsal is also seen in short-term memory. Subvocal speech recognition deals with electromyograms that are different for each speaker. More specifically, subvocal rehearsal and verbal maintenance are associated with the posterior left precentral gyrus. Words that are of high similarity minimize articulation, causing interference, and may reduce subvocal rehearsal. Broca's area has also been found to have activation in other studies exploring subvocal rehearsal.
