Constitution, Indexing and Enrichment of an environmental Sound Corpus – CIESS

Submission summary

Corpuses of environmental sounds are heavily used for scientific studies on human perception as well as a raw material for the creation of immersive soundscape for sound artists (immersive universe, video games …). The use of such corpus faces two major drawbacks. On one hand the annotation being a very tricky task with very few standards, it is difficult for scientists to disseminate corpuses, exchange data with peers or even search for existing corpuses and for specific sounds. On the other hand, existing corpuses does not always meet user needs.

Project CIESS, "Creation, Indexing and Enrichment of a corpus of environmental Sounds" aims to provide practical solutions and guidelines for creating, using and adapting such corpus. This ambitious project will create a strong interaction between the fields of perception, analysis and sound synthesis. These three components, rarely associated, are indeed necessary to grasps the whole complexity behind the creation and the use of specific sound corpuses. CIESS has a systemic approach considering the problem in its entirety and brings together three partners specialized respectively in each of these areas:

· OCTOGNE (PETRA) laboratory
· IRIT laboratory,
· AUDIOGAMMING, a young innovative company supported by incubator Midi-Pyrénées and two-times laureate of French Ministry of research and industry innovation contest.



CIESS will produce two major deliverables:

On one hand a corpus of environmental sounds thoroughly annotated and available to scientific communities as well as industrials and made available through the “Grand Equipement” program (TGE) ADONIS.

On the other hand CIESS will deliver the very first mock-up of a corpus enrichment framework. This framework will make use of automatic sound analysis tools as well as sound synthesis tools created specifically for that purpose. The OCTOGONE-PETRA laboratory will coordinate this development through an iterative process, in order to meet the requirements of perceptual studies.



IRIT will develop robust tools adapted to the high constraints of sound captured in real-life uncontrolled conditions. These tools allow the annotation of sound events, as well as the identification and computation of acoustic descriptors relevant to perceptual criteria studied.



AUDIOGAMMING, specialized in sound design and sound synthesis, will create the framework and the synthesis tools for the corpus enrichment. This framework is intended to act and to directly modify/enrich the sound events using automatic and perceptual annotations. These enrichments will be based on perceptual criteria established by OCTOGONE-PETRA laboratory.

Steps have been planned throughout the project to test the robustness and efficiency of developed tools.
