Labellers of connected speech corpora encounter a number of cases which are difficult to handle with a linear sequence of segmental labels. Based on material from a corpus of German unscripted speech, this paper presents non-sequential aspects of laryngeal activity for /x/ and /h/, and of supralaryngeal articulation in vocoid exponents of postvocalic /r/. Comparative data for /r/ from a corpus of German read speech indicate that differences across speaking styles may be independent of durational variation. It is discussed how models of the phonology-phonetics interface and Prosodic Analysis can account for the findings.
