APPARATUS, METHOD AND RECORDING DEVICE FOR PREDICTION VoIP BASED SPEECH TRANSMISSION QUALITY USING EXTENDED E-MODEL

摘要

PURPOSE: An apparatus, method, and recording medium for predicting VoIP(Voice over Internet Protocol) based voice quality are provided to calculate quality indexes using factors deducted from a design step. CONSTITUTION: A voice quality prediction apparatus includes an input unit(200) and a calculation unit(100). The input unit a transmission characteristic input unit(210), a reception characteristic input unit(220), a network characteristic input unit(230), a user characteristic input unit(240), and an environmentally characteristic input unit(250). The calculation unit includes an inter-end delay calculation module(110) for calculating inter-end delay time and a packet loss calculation module(120) for calculating packet loss rates.
