DCOSS supports PAMS (Perceptual Analysis Measurement System, ITU-T P.800), PSQM (Perceptual Speech Quality Measure, ITU-T P.861), and PSQM+. Using the DCOSS Voice Quality Testing (VQT), arecorded voice file (PCM or WAV) may be tested against a reference voice file (PCM or WAV) using PAMS, PSQM, and PSQM+. The VQT may be executing on a single timeslot at a time, but, using flexible parameters within the DCOSS Bulk Call Generator, the VQT may be executing from within Bulk Calling. VQT may also be executed manually by entering a reference voice file and a degraded voice file. The resultant of the VQT produces Listening Effort/Listening Quality as part of the PAMS algorithm and an MOS as part of the PSQM/PSQM+ algorithms.
