Simultaneous measures of electropalatography and intraoral pressure in selected voiceless lingual consonants and consonant sequences of German

摘要

This work assessed relationships among intraoral pressure (IOP), electropalatographic (EPG)measures, and consonant sequence duration, in the following obstruents, clusters, and affricates ofGerman: /t/, /∫/, /∫t/, and /t∫/. The data showed significant correlations between IOP and percentage of articulatory contact (PC) for all speakers, whereas duration and place of articulation (measuredby the EPG center of gravity) contributed less to IOP changes. Speakers differed in the strength ofthis relationship, possibly reflecting differences in vocal tract morphology or degree of laryngealabduction. Single-point EPG and IOP measures in fricatives showed consistent correspondencesacross consonantal contexts, but the relationships for the stops were more complex and reflectedpositional effects. Temporal compression was observed for both members of the cluster, but only thefricative portion of the affricate. Conversely, coarticulation was observed for both the stop andfricative portion of the affricate, but only for the stop portion of the cluster, possibly reflectingbiomechanical constraints. No clear differences were observed in coarticulatory resistance for stopsand fricatives. These data contribute to a limited literature on articulatory-aerodynamic relationshipsin voiceless consonants and consonant sequences, and will provide a baseline for considering longercombinations of obstruents.
