SAN JOSE, Calif. -- Psytechnics, the leader in voice quality measurement, will conduct the first ever independent tests to measure the level of voice quality provided by four major wireless carriers. The goal of the exercise is to understand how voice quality differs among the providers and to identify which may offer the clearest service.

Psytechnics will test the networks simultaneously under real-world conditions. Calls will be analyzed by Psytechnics' PESQ software (Perceptual Evaluation of Speech Quality). PESQ is the ITU standard for voice quality measurement.

The results of the tests will highlight to operators how their network voice quality varies in different conditions and locations. The analysis will also provide end users with an additional benchmark when considering which mobile network to use.

As the actual handset plays a role in affecting voice quality, Psytechnics will select leading mobile phone brands and rigorously test them on the four networks selected, using ASTS (Artificial Speech-like Test Stimulus) and PESQ. The results of these handset tests will also be recorded.

"Until recently, mobile carriers and customers were happy just to get a signal," said John Winchester, CEO of Psytechnics. "Now, customers, especially business customers, expect the best available voice quality. With the wireless arena becoming more competitive and consumers more knowledgeable and demanding, offering excellent quality will be a key differentiator among service providers."

Results of the evaluation will be compiled in September. Details of how operators perform will be made available to the service providers upon request.
