Benjamin Elie

I am a Postdoctoral fellow at LORIA, and at IADI in Nancy, France, since october 2013. As a member of the MULTISPEECH team, my research focuses on articulatory synthesis, namely human speech synthesis based on articulatory and acoustic models. Formerly, I worked as a PhD student at LAUM, in Le Mans, France, where I defended in November 2012. My thesis, supervised by François Gautier and Bertrand David, is about mechanical and acoustic characterization of stringed musical instruments applied to lutherie assistance. A complete CV (French) is available, here.
