Martin Graciarena - SRI International

Technical Manager, Speech Technology and Research Laboratory (STAR)

Martin Graciarena, Ph.D., is a senior research engineer in SRI International’s Speech Technology and Research (STAR) Laboratory. His research interests include noise robust features; voice activity detection; speaker, language, and speech recognition; non-audible microphone signal processing; and bird song processing.

At SRI, he is currently the co-principal investigator and speech activity detection task leader in the Defense Advanced Research Projects Agency (DARPA) Robust Automatic Transcription of Speech (RATS) program, and a team member of the Acoustic Background Characterization program led by Sandia National Laboratories. He has worked on projects such as DARPA’s Effective, Affordable Reusable Speech-to-text (EARS) program and Global Autonomous Language Exploitation (GALE) program, and the Intelligence Advanced Research Projects Activity’s (IARPA’s) Biometrics Exploitation Science and Technology (BEST) Program.

Prior to joining SRI, Graciarena was a researcher at the Biomedical Engineering Institute in the School of Engineering, University of Buenos Aires, Argentina.

He has more than 30 publications in peer-reviewed conferences and holds two patents. His Ph.D. in noise robust speech processing is from the University of Buenos Aires, Argentina.
