PESQ = Perceptual Evaluation of Speech Quality

Voice quality measurement nina l.jpg
Voice Quality Measurement (NINA+) interfaces

  • 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.

Network statistics l.jpg
Network Statistics interfaces

  • Based on the traced CS and PS transactions at Iub, Iu-CS, Iu-PS, Abis, A, Gb, MAP and ISUP interfaces:

    • Call setups, dropped calls, SMS, PDP context activations, routing area updates…

  • Stored to database
