In various tests we have our words pronouced before you have to answer the question (you enter a question) and after it (you answered correctly and you’ve got passed to the next one). If you have such questions going one after another the 1st sound (last one of the first question) starts playing but immediately interrupted by 2nd (first of of the next question). Generally, I can put it this way: give sounds a time to finish playing before transfer me to the next question.
