The aim of the article is an acoustic description of German vowel elongation during live sports commentary. It is not about long vowels that are in time relation to the other segments in the lexeme, but about those that, regardless of the quantity, have an additional duration (over 0.2 seconds) in a particular communication situation. The research material consists of two sports commentaries. The first concerns Germany's victory in the quarter-finals of the 2017 IIHF World Hockey Championship; the second - the gold medal won by Gesa Krause during the women's 3000 metres steeplechase at the 2018 European Athletics Championships.
