|
|
|
Min MOS LQK |
| Lowest MOS LQK score observed from start of the |
|
|
| voice stream |
|
|
|
| |
Max MOS LQK | Baseline or highest MOS LQK score observed from |
| |
|
| start of the voice stream |
|
|
| These codecs provide the following maximum MOS |
|
|
| LQK score under normal conditions with no frame |
|
|
| loss: |
|
|
| • G.711 gives 4.5 |
|
|
| • G.729 A /AB gives 3.7 |
|
|
|
| |
MOS LQK Version | Version of the Cisco proprietary algorithm used to |
| |
|
| calculate MOS LQK scores |
|
|
|
| |
Cumulative Conceal | Total number of concealment frames divided by total |
| |
Ratio |
| number of speech frames received from start of the |
|
|
| voice stream |
|
|
|
| |
Interval Conceal Ratio | Ratio of concealment frames to speech frames in |
| |
|
| preceding |
|
|
| using voice activity detection (VAD), a longer |
|
|
| interval might be required to accumulate 3 seconds |
|
|
| of active speech |
|
|
|
| |
Max Conceal Ratio | Highest interval concealment ratio from start of the |
| |
|
| voice stream |
|
|
|
|
|
Conceal Secs |
| Number of seconds that have concealment events |
|
|
| (lost frames) from the start of the voice stream |
|
|
| (includes severely concealed seconds) |
|
|
|
| |
Severely Conceal Secs | Number of seconds that have more than 5 percent |
| |
|
| concealment events (lost frames) from the start of |
|
|
| the voice stream |
|
