Progress towards a new government standard 2400 bps voice coder

In order to support the need for higher quality low rate voice communications for government, industry, and military customers, the United States Government is conducting a search for a new voice compression algorithm at 2400 bits per second (bps). The United States Department of Defense Digital Voice Processing Consortium (DDVPC), consisting of members from civilian and military branches of the US Government, is directing the testing and evaluation of several candidate 2400 bps algorithms. The goal of the DDVPC is to select a new algorithm which meets or exceeds the published requirements by mid 1996. The selected algorithm, to become the new standard, should be implementable in a small, low powered device by 1997. This paper describes the status of the testing and evaluation process from its beginning in early 1993 through the end of 1994
