Benjamin Elie

I am a former Postdoctoral fellow at LORIA in Nancy, France, from 2014 to august 2017. As a member of the MULTISPEECH team, my research focuses on articulatory synthesis, namely human speech synthesis based on articulatory and acoustic models. I am now at the Laboratoire des Signaux et Systemes (L2S). From 2009 to 2012, 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.
