Evaluation of the speech behaviour of reference speakers

Reference speakers, forensic phonetics, phonology, sociolinguistics, language variation


In forensic settings, when speech samples have to be compared, or in LADO investigations, it is crucial to be able to differentiate the speech behavior of cooperative speakers from the speech behavior of partly cooperative speakers. In order to perform this task, a comprehensive approach which encompasses knowledge from several linguistic subfields is needed. The theoretical framework of Natural Phonology which incorporates phonetic, phonological, sociolinguistic, and psycholinguistic knowledge proves useful to perform this responsible and considerably difficult task. For illustration purposes, the analysis of three case studies will be presented. Results show that phonetic and phonological variation and process application of partly cooperative speakers differs considerably from the results generally obtained in investigations on language variation (drawn from cooperative speakers). In addition, partly cooperative speakers tend to apply substitutions which are in contradiction to phonetic and phonological principles.

Author Biography

Sylvia Moosmüller, Institute of Acoustics, Austrian Academy of Sciences

Sylvia Moosmüller is Associate Professor of Applied Linguistics, Phonetics, and Phonology at the Acoustics Research Institute of the Austrian Academy of Sciences. Her main topics of research lie in the sociolinguistic, phonetic, and phonological description of Austrian language varieties and of selected, insufficiently described languages (e.g. Albanian). The results of her research find application in e.g. speech synthesis and forensic phonetics and acoustics.
