Presentation Transcript

  1. Ancient Sounds: mixing acoustic phonetics, statistics and comparative philology to bring speech back from the past Investigator: John Coleman Project Partner: John Aston Phonetics Laboratory Statistics Laboratory University of Oxford University of Cambridge @sounds_ancient Coleman supported by an AHRC Science in Culture Innovation Award

  2. What would comparative and historical phonology be like if we worked with sounds instead of symbols? • Can interesting statistical or signal processing methods give insights into language? • Could we bring back to life the sounds of dead languages?

  3. Phylogenetic phonetics After Schleicher (1860) Deutsche Sprache, and Aston, Buck, Coleman, Cotter, Jones, Macaulay, MacLeod, Moriarty, and Nevins (2011) Phylogenetic inference for function-valued traits: speech sound evolution. doi: 10.1016/j.tree.2011.10.001

  11. Objectives for 2015 (this award) “Triangulation backwards”: to reconstruct (audible) acoustic examples of the likely ancestors of words in: Romance (from Latin), Germanic, and Greek Develop techniques to overcome obstacles besetting these methods Presentations, publications and a workshop on the new methods To lay foundations for an “attack” on other branches: Celtic, Slavonic, Indo-Aryan
