Benjamin Elie

I am a Postdoctoral fellow at IMSIA (ENSTA ParisTech), in Palaiseau, France. As a member of the MAESSTRO ANR project, my work focuses on computer-based assistance for piano design. From 2009 to 2012, I worked as a PhD student at LAUM, in Le Mans, France. My thesis (in French), supervised by François Gautier and Bertrand David, and is about mechanical and acoustic characterization of stringed musical instruments applied to lutherie assistance. From 2013 to 2017, as a member of the MULTISPEECH team at LORIA (Nancy, France), my researches have focused on articulatory synthesis, namely human speech synthesis based on articulatory and acoustic models. Then from 2017 to 2018, I have been working on speech signal processing for phonetic studies at the Laboratoire des Signaux et Systemes (L2S, CentraleSupelec) . A complete CV (in French) is available, here.
