We were delighted to see our Spectrumview audio analysis app being used by Dr Helen Czerski , a renowned oceanographer and physicist from University College London, to explore a whole new acoustic world under the waves as part of the BBC 4 documentary – ‘Ocean Autopsy: The Secret Story of Our Seas’. Dr Czerski drops a hydrophone into the depths of the ocean and listens to, and visualises the sounds deep under the water using Spectrumview. In this excellent programme they explore how the sounds deep under the water (including man-made sounds) can affect marine life such as porpoises.
So the ocean surface is effectively a barrier for almost all sound, so we have no idea what’s going on down there, and it’s a different acoustic world. But you can listen in with the help of a little bit of technology.

Last week (14-17 July 2019) some of the OWR team had the pleasure of attending the annual IAFPA (International Association for Forensic Phonetics and Acoustics) conference which was hosted this year in Istanbul, Turkey.
It was a great opportunity for us to learn about the work of other members of the forensic phonetics and acoustics community from all around the world. One of the hot topics IAFPA this year was cross-language speaker comparison (Croatian-Serbian, Czech-Persian and French-English to name a few) We were delighted to see how much of this and other research from Switzerland and the Netherlands made use of the capabilities of our forensic automatic speaker recognition software VOCALISE.
We enjoyed every part of the conference but the highlight for us was undoubtedly our intern Linda’s poster winning the 2019 Best Student Poster award. As you can imagine, the team celebrated appropriately with Turkish beer.
We also showcased our advances in the use of Deep Neural Network (DNN)s using x-vectors in automatic speaker comparison and speaker profiling, presented by Dr. Finnian Kelly, our Principal Research Scientist.

More than just identity: speaker recognition and speaker profiling using the GBR-ENG database, Linda Gerlach, Finnian Kelly and Anil Alexander 14-17 July 2019, International Association of Forensic Phonetics and Acoustics (IAFPA) Conference, Istanbul, Turkey (Winner of 2019 Best Student Paper award)[download here]
Special thanks to Burcu Önder Gürpinar for 4 fantastic days of forensics and we look forward to showing you what we have in store for IAFPA 2020.
Linda Gerlach, who is interning with us from the Philipps-Universität Marburg in Germany, is working on a collaborative project between Oxford Wave Research (OWR) and the University of Cambridge. This work forms part of her MA thesis and seeks to better understand the relation of voice similarity ratings by humans and by an automatic approach. Results from this work could potentially help develop forensically sound methods and solutions for voice lineups (where a witness has to pick out the voice of a perpetrator from a lineup of foils).
This test takes about 15 mins and you will be presented with pairs of voice recordings by male speakers and asked to judge the similarity of each pair.
Oxford Wave Research are proud to be Platinum Sponsors of the 2019 AES International Conference on Audio Forensics.
Taking place in Porto, Portugal on June 18-20th 2019, this conference is dedicated to exploring advances in the field of Audio Forensics by providing a platform for research related to the forensic application of speech/signal processing, acoustical analyses, audio authentication, and the examination of methodologies and best practices.
We will be presenting our paper titled ‘Deep neural network based forensic automatic speaker recognition in VOCALISEusing x-vectors’ and will be giving a Platinum talk on ‘The who, the when and the what – challenges in the development of real-world solutions for forensic audio processing’.
This is the seventh AES conference devoted to the technical developments and practical approaches developing in the field of Audio Forensics and Oxford Wave Research will be demonstrating some of the latest (and coolest!) developments in speaker recognition and speech & audio processing.
The conference program will include paper presentations and discussions as well as Keynotes, Tutorials and Workshops on topics related to Forensic Audio.
Oxford Wave Research are delighted to be named partners of with the recently opened Centre for Forensic Phonetics and Acoustics (CFPA) at the University of Zurich. Opened on the 6th March 2019 the CFPA brings together research from a range of fields to address all areas of voice recognition in relation to forensic investigation.
Led by Prof. Volker Dellwo this centre will combine world-class research into forensic speaker recognition, voice disguise and voice line-ups with forensic services such as speaker profiling, speaker comparison, transcription, audio authentication and audio enhancement for both prosecution & defence.
As all great collaborations should, this one started with a few nice glasses in 2017 in Zurich.
Oxford Wave Research will be showing a whole host of exciting voice biometrics and audio processing products at the Home Office Security and Policing event from 5th-7th March at Farnborough International Exhibition and Conference Centre – Stand P2

In August 2015, the Home Office challenged UK businesses and academia to come up with ways to improve the speed, efficiency, and effectiveness of recovering and analysing data from digital devices seized from suspects under investigation. This was conducted through the SBRI (Small Business Research Initiative) competition run by Innovate UK on behalf of the UK Home Office.
Oxford Wave Research participated in this highly competitive call and was one of the eleven businesses and universities selected for Phase 1 funding. OWR successfully completed Phase 1 and was one of the five companies from the Phase 1 participants that was further selected for Phase 2 of the competition.
The funding for this challenge helped us to enhance our existing MADCAT algorithms for extracting and comparing fingerprints in audio or video, to using GPU-acceleration to perform millions of comparisons in seconds and hundreds of millions in tens of minutes. We further developed this into a client and GPU-server based architecture capable of sharing and comparing audio fingerprint data for high speed cross-case comparisons.
Our R&D team attended the SBRI Digital Forensics Showcase Event in London on Friday, 3rd November 2017, to showcase MADCAT WHISKERS, our high-speed media fingerprint comparison solution that was developed as part of this challenge.
The showcase event provided an excellent opportunity to demonstrate how we used the Home Office funding and input to develop and improve a product which is now being used in certain UK law enforcement agencies with tremendous results.
