Noise Robust Vocoding at 2400 bps
Robert David Preuss, Darren R. Fabbri, Daniel R. Cruthirds · 2006
We describe a 2400 bps noise robust vocoder (NRV) developed under the sponsorship of the United States Defense Advanced Research Projects Agency (DARPA) Advanced Speech Encoding (ASE) program. The NRV dramatically improves diagnostic rhyme test (DRT) intelligibility performance, as compared to the NATO-standard 2400 bps MELPe vocoder, in each of 3 harsh military noise environments exceeding 110 dBC SPL
