25. www.nethawk.fi 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.
