New ITU-T Recommendation for Non-Intrusive Voice Quality Assessment - Psytechnics, Opticom and SwissQual Win the ITU-T Competition

Ipswich, UK, Erlangen, Germany and Zuchwil, Switzerland (ots)

Psytechnics, Opticom and SwissQual today announced that their jointly
developed non-intrusive algorithm for voice quality assessment has
been selected by the ITU-T as the future recommendation.
In 2001 the ITU-T determined the need for a non-intrusive voice
quality measurement and announced an open competition in spring 2002
for the most accurate algorithm over a wide range of network
conditions. Five companies declared their intent to compete. During
the summer of 2003 Psytechnics, Opticom and SwissQual agreed to
combine their experience, expertise and individual models to create
the best possible algorithm. Each company contributed its own
algorithm, Psytechnics with NiQA, SwissQual with NiNA and Opticom
with P3SQM (jointly developed with KPN). After a considerable testing
and verification process, the collaborative effort from the three
companies was unanimously selected by the ITU-T as the future
recommendation.
The joint algorithm will open up new possibilities for network
operators and vendors to determine the operational voice quality
based on monitoring live calls. The benefit of this technology is
that no test signal is needed and only one point of the
telecommunication link is required to assess the voice quality.
"We are very pleased with the performance of the algorithm as it
proved not only to meet but also exceed the minimum requirements
defined by ITU-T," said Pero Juric, VP of Systems Engineering at
SwissQual. "It will enable almost unlimited voice quality monitoring
possibilities when integrated into equipment such as switches,
Voice-Gateways, VQE's or even mobile phones."
"We've created a very exciting measurement capability for the
industry," said Dr. Michael Hollier, CTO of Psytechnics. "I
anticipate that it will become common within network management
systems in one to three years."
"We are delighted that we have solved the engineering limitations
of having to set up test calls and achieve accurate voice quality
scoring with this innovative measure," said Michael Keyhl, CEO of
Opticom.
Evaluation licenses will be available in January 2004, with
commercial licenses to follow shortly thereafter.
