For WP4000 Low SNR mode, we need a speech codec with improved quality compared to Codec 2 700C (note the FreeDV 700D/E modes using Codec 2 700E vocoder mode for the codec). In this WP, the speech quality of the new candidate 700 bits/s mode will be tested.

  • Decide on scope of test (e.g. number of samples)
  • Collect samples from on line speech databases
  • Collect samples from Hams in multiple languages (e.g. English, German, Japanese)
  • Perform Subjective tests using WP2050 - Subjective Testing System #24
  • Evaluate results
  • Decide if new candidate should proceed to integration with WP4000 modem
