Volunteers Wanted for Forensic Science Research

The Alberta Phonetics Laboratory @ The University of Alberta is conducting research on forensic voice comparison, and we are looking for volunteers to help us with this research.

The purpose of the research is to demonstrate how to perform forensic voice comparison under conditions reflecting those of an actual case. We are basing this research on the conditions of an element of the Saskatchewan robocall scandal in which the outgoing voicemail message of a speaker of known identity had to be compared with the outgoing voicemail message of a speaker of questioned identity.

http://www.ottawacitizen.com/news/Tories+admit+they+sent+Saskatchewan+robocall/7922470/story.html

Our approach is based on relevant data, quantitative measurements, and statistical models, and we test the validity and reliability of our system under conditions reflecting those of the case under investigation.

Volunteers will be asked to make five telephone calls over the course of a week and each time leave the message: “You’ve reached Haste Research. Please leave your name, phone number and reason for call, and I’ll return your call as soon as possible.”

Volunteers completing the task will be given a gift certificate of $25 value.

If you are an adult male speaker of Canadian English, and are interested in participating, please send the following e-mail message to <apl@ualberta.ca> with subject line “potential volunteer”.

I am interested participating in the forensic voicemail research study. Please contact me by e-mail and telephone to give me more information so I can decide whether I want to participate. My telephone number is _______

• 2–7 June 2013
I organised a Special Session on Forensic Acoustics at the Internation Congress of Acoustics / ASA Meeting / CAA Meeting in Montréal


Since December 2012
I am a Subject Editor for the journal Speech Communication, including responsibility for submissions in the field of Forensic Speech Science, which is now explicitly listed in the subject coverage of the journal. Speech Communication was the publication venue of a seminal paper in the field: Champod & Meuwly (2000) The inference of identity in forensic speaker recognition. I want to encourage the submission of high-quality papers on Forensic Speech Science with the aim of making Speech Communication the top venue in this field. Please consider submitting your manuscripts to Speech Communication following the instructions in the Guide for Authors.
