Postseminarium följer direkt efter seminariet i institutionens pentry.

On May 17-18 a workshop on Vocal Profile Analysis (VPA) organised by Lisa Gustavsson, Gláucia Salomäo, and Anders Eriksson, will be held at the Department of Linguistics. The workshop is sponsored by a grant form Magnus Bergvalls stiftelse. It is a closed event but in connection with the workshop we will present our work in a seminar.

Abstract
VPA is a method for describing voice quality that was developed by John Laver and published in a book, The Phonetic Description of Voice Quality, in 1980. It is based on the assumption that all possible voice qualities (voice ‘timbre’ or voice ‘colouring’) can be described as a combination of a number of specified articulatory settings like lip spreading, tense vocal tract, creak etc. Based on these ideas, a protocol was later developed for use in speech therapy. Each setting was to be judged as Neutral (0) or deviating from neutral in 6 increasing steps. Forensic practitioners at J P French Associates have modified the protocol to make it more applicable to speech analysis in the forensic setting. The protocol used by the majority of practitioners in the UK lists 38 different settings grouped into three categories, vocal tract features, overall muscular tension, and phonation features and only involves 3 scalar degrees rather than six. The protocol will be explained in more detail in the seminar.

In addition to the Laver protocol another protocol (GRBAS) is also used in forensic casework.

The grant from Magnus Bergvalls Stiftelse has made it possible to invite four researchers from the University of York, all active in forensic phonetics and the use of VPA. At the seminar, the invited speakers will give short presentations (15 minutes + 5 for questions) of various aspects of VPA in forensics.
