Definitions

  • sample connection systems in which a known reference speech signal (source speech signal) is fed in at the source, via e.g. B. a telephone connection is transmitted and recorded at the sink. After the speech signal has been recorded, the properties of the possibly disturbed signal are compared with those of the undisturbed source speech signal in order to assess the speech quality.
