Investigating speaker individuality in the Swiss Standard German of four Alemannic dialect regions: Consonant quantity, vowel quality, and temporal variables

While German-speaking Switzerland manifests a considerable amount of dialectal diversity, until the present day the phonetic interrelation of Alemannic (ALM) dialects and spoken Swiss Standard German (SSG) has not been studied with an acoustic phonetic approach on the speaker level. In this study, out of a pool of 32 speakers (controlled for sex, age, and education level) from 4 dialectologically distinct ALM areas, 16 speakers with 2 dialects were analysed regarding SSG consonant duration (in words whose ALM equivalents may or may not have a geminate), 8 speakers from the city of Bern (BE) were analysed for vowel quality, and 32 speakers were analysed for temporal variables, i.e., articulation rate (AR) and vocalic-speech percentage (%V). Results reveal that there is much intradialectal inter- and intraspeaker variation in all three aspects scrutinised, but especially regarding vowel quality of BE SSG mid vowels and temporal variables. As for consonant quantity, while intradialectal interspeaker variation was observed, speakers showed a tendency towards normalised SSG consonant durations that resemble the normalised consonant durations in their ALM dialect. In general, these results suggest that a speaker’s dialect background is only one factor amongst many that influence the way in which Swiss Standard German is spoken.
