ASSTA Forensic Speech Science Committee
ASSTA’s Forensic Speech Science Committee (FSSC) evolved out of its earlier Forensic Speaker Identification Standards Committee, which was established in 1996, following discussions at the SST-94 conference. Its members, listed below, have considerable theoretical expertise in many aspects of Forensic Speech Science - in particular Forensic Voice Comparison, both with traditional and automatic methods.Click on their names to see their credentials.
Most FSSC members consult in real-world forensic case-work, both for police and private parties. Inquiries concerning forensic speech science case-work should be addressed in the first instance to: Dr. Shun Ishihara , or the secretary of ASSTA Dr. Catherine Watson .
Tony holds a first-class honours degree in forensic speaker identification from the Australian National University. He is the author of Forensic Speaker Identification - A Likelihood Ratio-Based Approach Using Vowel Formants, in LINCOM’s Studies in Phonetics. His book is an introduction to the proper evaluation of forensic-phonetic evidence and describes a forensic speaker discrimination experiment using vowel acoustics of Australian English. He has also published papers on issues relating to reference data for forensic speaker identification of Australian English speakers, and the use of diphthongs for discriminating male Australian English speakers. A member of the International Association of Forensic Phonetics & Acoustics, Tony has worked as a consultant in forensic speech analysis, and has performed case-work analysis for a number of law enforcement agencies.

Dr. Kinoshita has been a visiting fellow at the National Research Institute of Police Science in Japan, collaborating with Japanese forensic speaker identification experts. A member of the International Association of Forensic Phonetics and Acoustics, she continues to research forensic speaker recognition and has published several papers on it. Her research interests also include linguistic phonetics, and she also holds an M.A in phonetics from the Australian National University in which she conducted research on dialectal variation in Chinese. She is registered on the NSW Police scientific evidence expert list, and continues to do forensic voice comparison case-work.

Dr Bernard Guillemin
Dr. Guillemin is currently Senior Lecturer in the Department of Electrical & Computer Engineering at the University of Auckland, from which he holds a doctorate in Electrical & Electronic Engineering. His Ph.D. thesis focused on the acoustic analysis of infant cry patterns, in order to investigate the possibility of developing a diagnostic tool for early detection of risk of cot death. Over the years this research interest has expanded into the general area of speech science, with a particular interest in forensic speech science.
Dr. Guillemin has acted as an expert witness in Forensic Speech Science matters for New Zealand's High Court for over 20 years, a role which has expanded significantly in recent times. Some of his recent work, motivated by the increasing use by Police of recorded cell phone conversations as evidence in criminal trials, has focused on the impact on forensic speaker identification of the speech codecs used with the cell phone network (see for example his 2008 paper with C. Watson Impact of the GSM mobile phone network on the speech signal in the International Journal of Speech Language and the Law). He is a member of the Australasian Speech Science and Technology Association, the International Association of Forensic Linguists and the Institute of Electrical & Electronics Engineers.

She has casework experience in contested utterances.
As well as forensic speaker identification, Dr. Loakes' research interests include the phonetics of Australian languages, and connected speech processes and intonation in Australian English. Her publications include 'Variation in Long-Term Fundamental Frequency: Measurements from Vocalic Segments in Twins' Speech', 'Patterns of Frication in Australian English: An Analysis of /p t k/ in Connected Speech', and From IPA to Praat and Beyond.
