Bench-top system measures mobile sound quality

AVS has already been deployed by a tier 1 North American operator for acoustic speech evaluation of large volumes of returned mobile devices. Spirent says that AVS will ensure the mobile operators supplies to its retail outlets and end users deliver an excellent user experience. It aids forward logistics groups assure user experience by evaluating the acoustic speech quality.

With a breakthrough bench-top form factor, the system makes acoustic speech evaluation of large volumes of devices both practical and cost-effective. It enables forward logistics groups to statistically sample device lots for acoustic speech quality and have confidence that shipped devices will deliver an excellent user experience.

The same strategy works for mobile operator reverse logistics groups. They receive mobile phoine returns and poor audio quality is cited as one of the most common reasons. AVS enables acoustic speech quality evaluation to identify defective devices. Better identification of in-warranty devices with defects can lead to substantial reductions in device costs for operators. In addition, better identification of defective devices ensures only fully functional devices are sent for refurbishment, leading to improved user experience.

“We see an exciting opportunity to help operators improve their forward and reverse logistics processes with AVS,” said Des Owens, General Manager of Spirent’s Service Experience business unit. “In tests of actual returned devices, AVS showed that more than 60% of these devices had acoustic speech quality defects that were undetectable by less sophisticated subjective and functional tests. By improving operators’ ability to identify defective in-warranty devices, AVS can save operators millions.” AVS supports acoustic speech quality evaluation for any wireless technology including GSM, CDMA, UMTS and VoLTE.
