As a passionate engineer and an expert in audio and speech signal processing, I have a lot of experience in sound source separation, localization and recognition. A pioneer in the application of machine learning methods (NMF) to sound source separation, I am also co-founder of the startup Audionamix (2003). From 2008 to August 2021, I collaborated with the most prestigious audio signal processing labs in France, such as Télécom ParisTech and IRCAM, notably to apply my skills to the fields of robotics, music, spatialized audio and voice identity conversion. Since September 2021, I work at the startup Elsa (English Language Speech Assistant) as a Speech Scientist. Its flagship product, ELSA Speak, is a personal tutor who improves users' English pronunciation and reduces accent using advanced speech recognition and analysis.
