The subject of this investigation is the specific manifestation of the voicing contrast of German plosives during whispering, which is characterized by the absence of voicing. Using acoustic data from seven German speakers, temporal correlates of the voicing contrast—aspiration duration, closure duration, and duration of the preceding vowel—are comparatively examined for whispered and normally spoken plosives. It can be demonstrated that the manifestation of these correlates is neither affected by the loss of voicing during whispering nor programmatically enhanced in terms of a whisper-specific compensation strategy. This result aligns with the phonological concepts of the voicing contrast specified for German as a tenseness opposition.
