Telephone Game Quality Metric

  [vote for,

Problem: how do you objectively measure a voip channel's voice quality?

Solution: play the telephone game.

1) system A tells system B a random word

2) system B records what it heard and tells it back to system B

3) system A records what it heard and tells it back to system A

4) loop 2) until a pre-determined max iterations

5) let human being listen to each iteration (from worst to best)

6) once a human can accurately make out what was said stop

The iteration number is the TGQM.

TGQM=0 horrible unusable TGQM=1 barely usable TGQM=1000 as crystal clear as it gets

(optional) instead of relying on human in the loop, a computer voice recognition module can do this. HTGQM (human TGQM) / ATGQM (artificial TGQM)

       Search for PESQ and POLQA. There's a whole industry devoted to this with the basic idea of trying to build a mathematical model that can replace a human. The starting point is to do experiments to record people's perception of quality when presented with audio and video samples.
