This study examines factors which affect the pronunciation of Swedish learners of German as a foreign language. 18 samples were recorded and subsequently rated by German native speakers. The subject’s individual pronunciation results were linked to their respective answers regarding the following domains: Age of Learning, Length of Residence in a German-speaking country, Gender, Formal Instruction, Language Attitudes and Use and the realm of Ability and Skill. All of these variables have been subject to research on pronunciation in former studies. With the help of new questions and a modified method, this study aims to find new influential variables and support or disprove former findings. The most influential variables were Language Use, Length of Residence, Age of Learning, Special Pronunciation Training and Gender. The field of Ability and Skill showed inconclusive results, Formal Instruction had no significant influence on pronunciation and no new variables could be detected.
