Hervé Glotin began his scientific career developing human speech recognition systems. He has adapted these methodologies and extended them to investigating biodiversity by ascertaining information from acoustical and visual data using scaled machine learning techniques. What this means is that his team develops methods to process acoustical and visual data in real time, even when recording systems are sampling at 1 MHz! Currently, Hervé is head of the Scaled Acoustic Biodiversity (SABIOD) Big Data which is funded by the Centre National de la Recherche Scientifique (CNRS) and he leads the Information Dynamics and Integration group in France. He has co-authored more than 100 peer-reviewed articles and has organized several international workshops on machine learning with bioacoustical data.

Hervé’s research group explores new mathematical transforms to view and process data in novel ways in order to obtain more information from recordings. Some examples include developing techniques to:

  • distinguish up to 500 different avian species from natural environment recordings that contain anthropogenic noise
  • count and track individual sperm whales
  • track bats
  • individually identify Amazon River dolphins

Eduardo has dedicated much time and effort in promoting bioacoustical research in Mexico and other countries. One barrier to such research has been access to quality recording and processing equipment. Eduardo has developed low-cost, high-quality recording equipment and acoustic cameras. He has open sourced the instructions for equipment construction. If you are unable to access these publications you may contact Eduardo at the above email address to obtain a PDF copy. If you have further questions, or would like to invite Eduardo to your facility to teach a workshop on equipment construction, please contact him at the above email address.
