The state\u2010of\u2010the\u2010art algorithm computes a certain measure of disturbances surface, and applies a <jats:italic>cognitive model<\/jats:italic> to map the computed value to the scale used mean opinion score (MOS). We note that many parameters, including the used metric of <jats:italic>L<\/jats:italic><jats:sup><jats:italic>p<\/jats:italic><\/jats:sup> space, do not appear to be robust enough in terms of the performance of the algorithm. First, we search for optimum <jats:italic>L<\/jats:italic><jats:sup><jats:italic>p<\/jats:italic><\/jats:sup>\u2010norms over the frequency\u2010\u2010time domain disturbance surface. The optimum <jats:italic>L<\/jats:italic><jats:sup><jats:italic>p<\/jats:italic><\/jats:sup>\u2010norms yield the most desirable correspondence between symmetric\/asymmetric disturbance terms and subjective scores. New features are added to the cognitive processing algorithm. Improvements are substantial, but still only incrementally improve the performance. Limitations and bottlenecks of the current standardised approaches, as well as emerging new ideas, are reviewed. Finally, we call for more innovative, rather than renovative, research efforts in objective speech quality measurement for fundamental enhancement of the algorithm.
