      ABSTRACT = {This study examines laughter co-occurring speech, so-called speech-laughs in a corpus of German spontaneous dialogues. Against a common expectation the majority of labelled laughs are speech-laughs. The phonetic characteristics for this type of laughter is an additional aspiration (different for voiced and unvoiced sounds) which is sometimes accompanied by a vibrato voice quality and a duration of two syllables. In a perception test the hypothesis of an acoustic continuum from smile to laugh has been rejected. The results and the problems are discussed in the context of paralinguistic phonetics.},
