F0 generation is an effective instrument for identifying intonational foreign accent (IFA), as it can be applied to determine the relevance of observed deviations in the intonation patterns produced by non-native speakers of a language, This study aims to show that the method of intonation description that is used and that also serves as the basis for F0 generation determines the form of the observed IFA which is examined both in the German speech of native speakers of American English and the American English productions by Germans. Two approaches to intonation description and generation are introduced: a category-based approach which identifies IFA in terms of tonal categories and a data-based approach which represents the F0 contour in terms of an approximation function determined by six parameters and thus focuses on the phonetic aspects below the category level.
