The use of composite measures is necessary as we cannot expect the simple objective measures (e.g., LPC-based) to correlate highly with signal/noise distor-tions and with overall quality. Voice measurements include MOS (Mean Opinion Score), round trip delay (RTD), jitter, clipping, voice levels, etc. The output-based speech quality assessment method has been widely used and received increasing attention since it does not need undistorted signals as reference. Objective measures for quality assessment are required in order to evaluate such algorithms. Assessing VoIP speech quality in a non-intrusive manner is a challenging task. Examine instructions and requirements, create a structure, and write down a perfect and unique text. Intrusive Method of Speech Quality Assessment system provides real-time voice quality measurement across a diverse set of networks.
