BEA
The Bureau d’Enquêtes et d’Analyses pour la Sécurité de l’Aviation Civile (BEA) conducts independent safety investigations into serious civil aviation accidents and incidents in France in order to establish the circumstances, causes and contributing factors. It also contributes to investigations led by its international counterparts in accordance with international regulations.
The Recorders and Avionic Systems (PESA) division is part of the BEA’s Technical Department which is responsible for the examinations carried out as part of the safety investigations. PESA analyses Cockpit Voice Recorders (CVR), radar data, air traffic control communications, audio and video data, and on-board computers and systems. As part of the BLeRIOT project it is coordinating, PESA contributes to 1) modelling the audio and acoustic chains from the cockpit to the CVR, 2) generating non-sensitive, labelled, CVR-like speech data, and 3) evaluating the transcription systems being developed.

DGA EV
DGA Flight Testing conducts testing and provides expertise on all types of aircraft, their equipment, and weapon systems.
As a guarantor of quality and risk management, DGA EV operates within the framework of development, qualification, and acceptance of aircraft for the French government. The center also contributes to efforts related to airworthiness and certification of civil aircraft, as well as export support.
As part of this BLeRIOT project, DGA Flight Testing focuses on an objective measurement of speech intelligibility, and in providing in-flight and on-ground voice and noise recordings to partners

IRIT
The Toulouse Institute for Computer Science Research (IRIT) is a Joint Research Unit (UMR 5505, CNRS, University of Toulouse) with 600 members organized into seven research departments.
The SAMoVA team (Structuring, Analysis, and Modeling of Video and Audio Content) is part of the Signals and Images department at IRIT. Its research activities focus on signal analysis (audio, speech, music, images) for feature extraction and segmentation at different temporal scales, and the modeling of multimedia objects (speakers, languages, human shapes and gestures), generally using deep learning methods. As part of this BLeRIOT project, the SAMoVA team focuses on speaker diarization (segmentation and grouping into speakers) and on an objective measurement of speech intelligibility.
Involved people:
- Mateo Gaudin (02/25 – 07/25)
- Niel Mbede (05/25 – 07/25)

LISIC
The Laboratoire d’Informatique, Signal, Image de la Côte d’Opale (LISIC) is the information science Research Unit (UR 4492) of ULCO, with around 80 members organized into four teams.
The LoRAL (Low-Rank Approximation and Learning) research group is part of the SPeCIFI team at LISIC. Its research activities focus on the development and the applications of low-rank-based models. As part of this BLeRIOT project, the LoRAL group focuses on human-in-the-loop speech separation from CVR recordings.

RESEDA
For more than 60 years, the RESEDA laboratory of the DGA-EP has been contributing to the safety of air operations within the Ministry of the Armed Forces by participating in technical investigations launched by the BEA-é (Bureau Enquêtes Accidents pour la sécurité de l’aéronautique d’État), including those involving the Air Force fleet, the Army, the Navy, the DGA, the Civil Security and the Gendarmerie. RESEDA provides essential technical support for the smooth running of investigations, in particular by extracting and then processing data and audio recordings from the CVR. Each year, RESEDA participates in more than twenty investigations aimed at understanding the circumstances of an accident or incident in order to make recommendations for the improvement of air safety in the State.
