PESQ Perceptual Evaluation of Speech Quality
25
Voice Quality Measurement (NINA)
  • No-reference approach for evaluation listening
    quality of speech files.
  • NetHawk solution is based on SwissQuals 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.

26

Column Description
Amplitude Clipping (DL/UL) Estimated amount of amplitude clipping in percentage.
DC Offset (DL/UL) Constant value of the input signal in percentage.
MOS-LQO (DL/UL) Overview about the sound quality in a single number result. 1 bad 5 excellent speech quality.
Noise Level (DL/UL) dB Noise Level displays an estimation of the background noise floor in decibel.
Pitch Frequency (DL/UL) Hz Pitch frequency of the input signal in hertz.
Problem Code (DL/UL) Possible cause for the speech degradation.
Signal Class (DL/UL) Analyzed signal classified into Clean speech / Noisy speech / No speech
Speech Activity (DL/UL) The higher this number is the higher is a speech density in an input signal.

Speech Level (DL/UL) dB R.M.S. level of all frames containing active speech in decibels.
Static SNR (DL/UL) Static SNR displays the signal-to-noise ratio of the signal.
