    1997 Speaker Recognition Evaluation
    Echo Cancelation Software

  • The echo cancelling software (ec_v2.5.tar.gz) that is applied to telephone data, may be obtained from Mississippi State University.
  • The LDC has provided a perl script (mu_ec.perl) that will take a sphere-headered, 2-channel mu-law waveform file as input, apply the MSU/ISIP echo cancellation software, and produce a sphere-headered, 2-channel mu-law waveform file as output. In the process, it adds the following to the sphere header of the output file: echo_cancellation ec-v2.5

  • In running the echo canceller on sparcs (ss20, SPARCserver-1000), it takes between 3 and 4 times realtime to operate.
