All spoken languages show phonetic variation. Some variants are salient and can be the topic of lay persons’ metalinguistic comments or jokes, other variants are more subtle. Variation can be due for example to the speaker's origin, to the individual, to language contact (e.g. foreign accent), to the speaking style, to the phonetic environment or to the speaking rate. The focus of this course lies on phonetic variation in German, for example between or within Swiss German dialects or national varieties of Standard German; however, other languages can be taken into consideration as well. Participants will be doing analyses and measurements with their own recordings, which can be in (Swiss) German, English or French.
