IAFPA runs an annual conference to facilitate the exchange of phonetic and acoustic research, methodology and best practice for the analysis of recordings and interpretation of findings, and any other issues pertinent to the organisation’s aims.

Student Travel Grants

We are delighted to offer 2 travel grants of £250 for students who are self-funding attendance at our conferences. These grants are kindly sponsored by Equinox, the publisher of the International Journal of Speech, Language and the Law, who will offer two grants named after this journal.  Student members should look out for the call for grant applications prior to each conference.

IAFPA 2023 – Zürich, Switzerland

The 31st International Association for Forensic Phonetics and Acoustics (IAFPA) Conference will be held from 9-12 July 2023 in Zürich. It is being hosted by a team of IAFPA members from the University of Zürich (UZH) / Centre for Forensic Phonetics and Acoustics (CFPA) and Zürich Forensic Science Institute (FOR). Find more information on the conference website.


Due to technical issues resulting from a security breach at the University of Zurich, the conference website is not currently accessible outside of Switzerland. We are hoping this problem will be resolved shortly, but for now, the call for abstracts can be found below.

Call for abstracts:

We invite proposals for papers on topics including, but not limited to:

  • Speaker/voice comparison
  • Speech and audio enhancement
  • Transcription
  • Speaker profiling
  • Questioned utterance analysis
  • Authentication of recordings
  • LADO (Language Analysis for the Determination of Origin)
  • Automatic speaker recognition/comparison
  • Voice line-ups
  • Retrieval of population data
  • Exceptional case reports
  • Method validation and proficiency testing

Online presentations may be considered for participants located far away from Zürich (outside of the Europe) for whom in person participation would be particularly challenging. We welcome abstract submissions from such people, but please be advise that the exact distribution format of these presentations is yet undecided and will depend on the quality of the submissions. If you do not intend on attending the conference, but wish to be considered for an online presentation, please note this on your abstract.

Call for Special Session on Casework:

The organizers of IAFPA 2023 are delighted to announce that a Special Session focusing on Casework Practise is being planned.
Therefore, we invite researchers and practitioners involved in forensic phonetic and acoustic cases to submit abstracts for presentations covering previous cases or general casework issues. Topics of particular interest include, but are not limited to:

  • Speaker/voice comparison methods (e.g., auditory-perceptual, acoustic-phonetic, automatic, or a mixture of different methods)
  • Areas of forensic speech and audio analysis (e.g., audio enhancement, speaker profiling, transcription of disputed utterances)
  • Exceptional case reports
  • Novel or emerging analysis techniques (e.g. relating to acoustic or automatic methods)
  • Casework issues (e.g., validation, reporting conclusions, limits of forensic phonetics)

The topics can be taken from actual cases or framed as open questions/problems, which can form a framework for subsequent discussion. The abstract format, submission deadline, and submission portal follow the main IAFPA 2023 submission guidelines. Submissions for this Special Session should be for oral presentations only. Submissions for posters are accepted but will only be considered for the general poster sessions.

Format and deadlines (for all abstract submissions):

Length: maximum 500 words, excluding title and references; figures may be included, but the document should not exceed two pages. Please use this template (DOCX, 108 KB) and submit your abstract via EasyChair

Important dates:

  • Deadline for oral papers and posters: March 27, 2023.
  • Deadline for special session: March 27, 2023.
  • Deadline for work-in-progress: May 22, 2023.
