  1. 1. FAST AND EASY – NO REFERENCE NEEDED NIQA makes quality evalu- ation based on actual call audio, no reference required. RELIABLE QUALITY SCORING NIQA MOS scores are of similar or higher accuracy than in ITU-T P.563 stan- dard. ASSESS VOICE QUALITY IN REAL TIME BY NIQA NIQA allows network own- ers to receive notifications about voice quality degra- dation, detect problematic trunks, destinations and initiate proactive mainte- nance. PROACTIVE APPROACH NIQA will inform your maintenance team to take immediate actions on qual- ity improvements before receiving complains from your valued customers. NIQA – Non-intrusive Voice Quality Analyzer Non-intrusive voice quality measurements are pas- sive methods for measuring voice quality on traffic generated by existing callers. The measurements can easily be applied both for packet-switched and circuit-switched networks. Non-intrusive testing is a simple and cost effective, which is not using bandwidth or traffic resources being fully software based. Non-intrusive methods that return speech quality score (MOS) are the key means for measuring actual callers’ traffic. Sevana NIQA (Non-Intrusive Voice Quality Analyzer) technology is based on a database of trained etalon associations. Each association cor- responds to a group of files that have close expert estimations of sound quality and common set of reasons for sound quality degradation. Sevana NIQA has been tested utilizing the same ITU-T speech database that is used for conformance testing of P.563 algorithm. Atotal of 376 English language recordings passed through the system during testing phase. All recordings were sorted into 4 groups depending on their MOS scores (represented in the documentation attached to the sound database). For all groups of recordings we figured out an average expert score and average NIQAscore. In order to illustrate comparison with P.563 we also calculated average errors for P.563 and NIQA scores for the same tests. Tests clearly show that NIQAallows receiving much higher accuracy between generated quality scores and expert estimations. Growing business cannot afford loosing customers due to bad quality. NIQA helps to automatically predict end-user sat- isfaction. One should be aware that SLA is kept valid. NIQA allows: ● Real-time monitoring ● Easy network testing, enabling quick optimization ● Fast reliable fault detection ● Proactive customer support ● No royalties or other annual fees ● Professional tool accessible to everyone ● Outstanding value – ask for an offer!
