Optimizing VoIP Test Sequences for Speech Quality Assessment

The patent segments the continuous parameter space of network conditions into discrete regions of interest based on degradation severity. Instead of exhaustively testing all possible conditions, the system divides the parameter space (packet loss rate, jitter, etc.) into meaningful segments and focuses testing resources on the most critical regions where quality degradation occurs, thereby reducing overall testing time while maintaining assessment accuracy.

The system dynamically adjusts test parameters based on observed quality degradation patterns. By changing parameters such as packet loss rate and jitter values to focus on regions where quality targets are not met, the system optimizes the testing process to achieve comprehensive quality assessment with fewer test sequences, thus reducing time loss while preserving measurement precision.

The patent applies local quality by concentrating testing effort on specific regions of interest within the parameter space where edge-devices exhibit problematic behavior. Instead of uniformly distributing test sequences across all possible conditions, the system identifies local regions where quality degradation is most likely to occur and allocates more test sequences to these areas, achieving reliable assessment with improved overall testing efficiency.

The system performs partial testing by focusing on the most critical regions of interest rather than exhaustively testing all possible network conditions. By applying excessive action locally (concentrating test sequences in problematic regions) rather than uniformly across the entire parameter space, the system achieves sufficient reliability for quality assessment while significantly improving productivity.
