Researchers will have listeners hear recorded speech from both groups, produced in different situations (interactive and non-interactive tasks). The listeners will then choose what they heard from a list of words. The main goal is to see if interactive situations change how clearly speech is understood for both groups. This study is for people aged 18 to 65 who are native English speakers, have good hearing, and no known speech, language, or neurological disorders. The study is currently unclear about its recruitment status.","Not specified.",105,"You will participate in one 20-minute session where you listen to recorded speech and indicate what you heard by clicking on words.","Not stated in the trial record.",[],"v2"]
