Voice Quality Measurement (NINA+)
- No-reference approach for evaluation listening quality of speech files.
- NetHawk solution is based on SwissQual’s NiNA+ algorithm:
– In comparison to ITU-T P.563 – where SwissQual is also owner
partially – NiNA+ has much less complexity.
- Restricted to narrow-band speech:
– AMR-WB signal can be analysed but only the narrow-band spectral
parts are taken into account allowing to predict transmission errors of
the AMR-WB against error-free AMR-WB transmissions.
- Minimum period of the sample speech must be of five seconds. Speech
period can be more than 20 seconds but the only first twenty second is
analysed:
– NiNA+ makes use of a sophisticated pre-processing step that checks
for silence and sufficient speech activity in the signals.
