Berkeley Using Optical Scanners To Recover Decayed Recordings Of Languages That Have Died

Among the thousands of wax cylinders in the University of California (UC) Berkeley’s Phoebe A. Hearst Museum of Anthropology are songs and spoken-word recordings in 78 indigenous languages of California. Some of these languages, recorded between 1900 and 1938, no longer have living speakers. The history on the cylinders is difficult to hear. The objects have deteriorated over the decades, mold eating away at their forms, cracks breaking through the sound.
