Sevana PVQA test results

Below are the PVQA analysis results for the last 20 calls on the demolab numbers where the users selected the PVQA demo. The caller voice is recorded for 15 seconds and sent to Sevana PVQA software for voice impairments analysis.

The test values indicate the probability of corresponding impairments:

SNR-00
- Signal to Noise Ratio
DeadAir-01 and DeadAir-00
- These are two types of dead air detected. Dead air is very likely to be caused by packet loss.
AMPC
- Amplitude Clipping
VADC
- VAD Clipping
Click
- Clicking/Crackling
Average
- The average of the above probabilities

The current settings consider ideal silence as dead air, so ideally there should be some background noise for most adequate results. The 15th second of a recording has usually some indication of degraded quality, because the recording is stopped abruptly in the middle of the speech.
