WP2060 - Subjective Testing

Open drowe67 opened this issue 2 years ago • 0 comments

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 #24
  • [ ] Evaluate results
  • [ ] Decide if new candidate should proceed to integration with WP4000 modem
