This tool, called No Language Left Behind, is part of Meta’s R&D project to create a universal speech translator, which would help the growth of Facebook, Instagram, virtual reality destinations, and other of its social media properties. The open source approach — with the code available on GitHub — is taken to attract more technicians to the development work. In an abstract, Meta explains that this universal translator is “driven by the goal of eradicating language barriers on a global scale” with the help of machine learning technologies.
