A Forensic Speaker Identification Study. An Auditory-Acosutic Analysis of Phonetic Features and an Exploration of the "Telephone Effect"
|
|
|
|
Abstract:
This study investigates the formant, fundamental frequency, and speech tempo parameters in a forensic speaker identification setting and whether these are adequate features to use in an auditory-acoustic analysis. Furthermore, the 'telephone effect' as described by Künzel (2001) is examined and analysed in terms of whether it applies to the aforementioned phonetic features. The results showed that all three parameters proved to be efficient and appropriate for forensic speaker identification practices, but that the articulation rate of the disputed sample was heavily affected by a task-effect. In terms of the intercept recordings, F1 values, especially those of close vowels, were found to be affected, consistent with Künzel's findings (2001). Mean fundamental frequency values were not altered by the intercept sample, but the standard deviation was, resulting in values twice as high compared to direct recordings. ; Aquest estudi investiga els paràmetres de formant, freqüència fonamental, i velocitat de l'articulació en un entorn de la identificació forense del parlant i si aquests paràmetres són adequats per utilitzar en una anàlisi auditiva-acústica. D'altra banda, 'l'efecte telefònic' descrit per Künzel (2001) és examinat i analitzat pel que fa a si és aplicable a les característiques fonètiques esmentades anteriorment. Els resultats van mostrar que els tres paràmetres són eficients i adequats per a les pràctiques d'identificació forense del parlant, però que la velocitat de l'articulació estava molt afectada per un efecte de tasca. Pel que fa a les gravacions interceptades, els valors de l'F1, especialment els de les vocals tancades, es van trobar afectats, la qual cosa és consistent amb els resultats de l'experiment de Künzel (2001). Els valors mitjans de la freqüència fonamental no van ser alterats per l'enregistrament telefònic, però la desviació estàndar, sí, mostrant valors el doble d'alts comparats amb les gravacions directes.
