Once upon a time, I took several semesters of noncredit Spanish classes. I did OK in reading, but in situations where I needed to speak to someone in Spanish I froze up. Maybe I should’ve had a cocktail first.
A study by the University of Liverpool, Maastricht University, and King’s College London found that people who drank a small amount of alcohol were judged to have better pronunciation in a foreign language. Alcohol impairs executive function including the ability to remember things, so it should hamper speaking a second language. But it also lessens social anxiety.
Interestingly, in this study, outside observers rated those who had consumed a low dose of alcohol significantly better speakers than the control group who had non-alcoholic beverages . The actual participants did not rate themselves higher.
So if you try this at home, stick to only one drink and don’t judge yourself. You’re conversing better than you think.
