I received my PhD in 2006 entitled: "Confidence measures in speech processing and applications". From 2007 to 2009, I was a postdoc in Ireland (UCD) working within the CNGL project who addressed the adaptation of digital content to culture, locale and linguistic environment at high volume, speed and quality. Since 2009 I am an assistant professor, firstly in University Paris Descartes within the LIPADE laboratory, and now, as a researcher of the SAMoVA team at Institut de Recherche en Informatique de Toulouse.


My main research field is about characterizing voices from people with production disorders. For example, I work on automatic technologies to determine the intelligibility of voices and to define pronunciations disorders. I am also intesrested by confidence measures in speech processing in general.
