POLQA
POLQA – which stands for “Perceptual Objective Listening Quality Analysis” – is the standard, next-generation voice quality testing technology for fixed, mobile and IP based networks. It offers a new level of benchmarking capability to determine the voice quality of HD Voice, 3G and 4G/LTE mobile network services.
POLQA is also the only HD quality assurance algorithm that has official ITU-T approval. In 2010 POLQA was selected to form the new ITU-T voice quality testing standard, P.863, after rigorous testing and a four-year competition between the leading companies in speech quality testing.
And an enormous amount of effort has gone into ensuring POLQA works quickly and accurately. For example, more than 100,000 samples of mobile and VoIP phone calls were used to train and optimize the POLQA algorithm, meaning that POLQA is superior to existing standards, and has overcome all known issues and limitations of PESQ.
POLQA, which was developed in conjunction with OPTICOM and TNO, offers immediate, strong support for testing of new wideband 4G/LTE networks delivering HD-quality voice services.
