I do fieldwork and laboratory analyzes on various languages of Europe, Latin America, Africa and South East Asia that represent a great diversity of linguistic families. I study standard spoken voice as well as non standard speech registers such as shouted, sung, whispered voices, whistled speech, the spoken mode of drums and even the sung mode of other traditional musical instruments. Each of these speech registers complement standard spoken speech in contexts where normal speech wouldn't be appropriate. They provide alternative insights to the possibilities and limits of modification/degradation of the acoustic speech signal.


New methods have been developped in several domains:


  • In production, including in noise and different natural environments to analyze their impact on speech
  • In perception, to verify hypotheses infered from phonetic analysis, by perceptual interrogation of speakers (intelligibility tests; word, phoneme or tone recognition in different languages)
  • A new Atlas of whistled and instrumental speech is being currently mounted thanks to the data collected around the world and to fieldwork in 13 different linguistic communities (25 months on the field in several periods).
  • We developped new methodologies to collect data in conditions of endangered languages: (a) Data collecting was made respecting the local and national ethics requirements and in collaboration with national profesionnal Archives (ALIM, Museu Goeldi) and international ones (ELAR, SOAS, London); (b) We document the contexts of use (story telling, telecommunication, hunting...). (c) We returned the data to the linguistic communities in the form of DVDs, CDs, articles, raw data, or organized Archives, and we often provided training in video and audio documentation.

English abstract:

Whistled languages, which are linked to particular biotopes, represent a little studied valuable oral patrimony. They are analysed here in their diversity thanks to a 14 months fieldwork and collaborations done in ten linguistic communities during more than one year. Whistled speech relies on phonetic elements of the original spoken voice in order to communicate in the distance or in the ambient noise. It enables high intelligibility of sentences in difficult conditions of listening. A typological description is developed here thanks to the collected data. The linguistic types depend on the phonology of the concerned languages. A comparative study of the spoken voice, the shouted voice and the whistled speech shows that whistling enables to prolong the acoustic strategy of overcoming noise as the distance of communication increases. It therefore enables the human speech to naturally develop properties, which elaborate a true system of telecommunication. The transformation at play in whistled speech is a practice that requires complementary learning but it is based on natural perceptive capacities. For example the results of a perception test show that French persons knowing nothing of whistled spanish vowels can intuitively identify them. In order to analyse these different aspects, the proposed methodology uses the tools of phonetics, phonology, bioacoustics, sociolinguistics, psychoacoustics and psycholinguistics.
