Evaluate voice experience for VoNR, VoLTE, VoWi-Fi, and OTT services with Umetrix Voice.

Highlights

Umetrix Voice evaluates end-to-end voice experience across any mobile device and any voice service, including VoNR, VoLTE, VoWi-Fi, OTT, and legacy 3G — using Perceptual Objective Listening Quality Analysis (POLQA) speech quality measurement.

Key capabilities

  • Six simultaneous device channels via Bluetooth® control — reduces test completion time by 30–50% compared to previous Umetrix Voice models
  • Combined call performance and speech quality testing in a single pass — reduces typical test plan time by an additional 10–20%
  • POLQA V3 algorithm support for narrowband and HD speech quality analysis at up to 48 kHz bandwidth
  • All wideband codecs supported, including Enhanced Voice Services (EVS)
  • Consistent measurement methodology across any mobile device platform for direct service and device comparisons

Test approaches

  • Mobile-to-mobile: supports HD codecs for VoNR, VoLTE, VoWi-Fi, and OTT voice testing
  • Mobile-to-IP Multimedia Subsystem (IMS): isolates uplink and downlink with the optional Umetrix HD Voice Server deployed in the carrier core network
  • Mobile-to-public switched telephone network (PSTN): Spirent-hosted cloud endpoint isolates uplink and downlink using narrowband codecs
  • Automation and reporting
  • Automated test setup, result validation, data aggregation, and reporting
  • Comparative reports across device models, service providers, or service types (VoNR, VoWi-Fi, VoLTE, 3G, OTT)
