Malden is pleased to announce that POLQA®, the newest standard for evaluating speech quality (ITU_T P.863), is now available on their MultiDSLA speech performance analysis tool.
Sill providing PESQ scoring, the MultiDSLA can now include support for the ITU-T Rec. P.863 POLQA® algorithm which has been developed to deal with some of the weaknesses inherent in PESQ.
You should be considering testing with POLQA® if you:
- Are using either wideband or super-wideband codecs.
- Use codecs that employ time-warping.
- Work with CDMA terminals and/or networks.
- Have a network that uses AMR codecs.
- Test through acoustic interfaces.
- Are concerned about voice quality enhancement and noise reduction devices/processes.
The principle is similar to PESQ – comparing the clean reference file with the degraded file from the network - but the test methodology is different. POLQA® has two models, one for Narrowband and one for Super-wideband. The Super-wideband model can be used for any network. The Narrowband model provides compatibility with PESQ NB and narrowband subjective test data.
MultiDSLA makes it easy to use POLQA®. Malden's long experience in the application of speech quality metrics ensures that you will be getting useful results as soon as the option is enabled on your MultiDSLA system.
