GL Communications Inc. has unveiled its innovative Voice Quality Testing (VQT) solutions, designed to deliver objective assessments of speech quality across a variety of communication networks. These include advanced technologies such as 5G, VoLTE, VoIP, as well as traditional systems like PSTN and TDM. The emphasis on end-to-end solutions ensures that users experience consistent and high-quality voice services.

Importance of Voice Quality
Maintaining excellent speech quality is vital for voice services. Various network impairments—including delay, jitter, packet loss, and noise—can detrimentally affect user experience. GL’s VQT solutions are engineered to systematically measure these metrics, automate testing procedures, and pinpoint specific voice quality issues across diverse environments, including laboratories and field operations.
Comprehensive Testing Solutions
GL Communications offers VQT solutions that are fully compliant with international standards such as POLQA® (ITU-T P.863) and PESQ (ITU-T P.862). These standards serve as benchmarks for objective speech quality assessment. By integrating various tools like vMobile™, VQuad™, and AutoVQT™, GL provides a versatile framework that supports both portable and laboratory-based testing, as well as automated end-to-end voice quality validation.
Objective Assessment Methods
The VQT software from GL is capable of comparing a reference voice file with a degraded version received through the network. This allows for a precise evaluation of speech quality. The software supports the latest POLQA® versions, enhancing assessments for VoLTE and 5G services, while also accommodating legacy PESQ evaluations. It conducts comprehensive analyses across different audio bandwidths and modern codecs, including EVS, OPUS, and LC3.
Enhancing Testing Efficiency
Vikram Kulkarni, Sales Director of GL Communications, emphasizes that these integrated Voice Quality Testing solutions empower engineers to objectively evaluate speech quality across various communication platforms. The combination of portable field testing, automated processes, and centralized reporting helps identify voice impairments, optimize network performance, and validate voice services effectively.
Portable Testing Capabilities
The vMobile™ tool facilitates automated voice quality testing for mobile devices and radios in both field and laboratory settings. It supports multiple communication technologies, including 3G, VoLTE, and 5G. Key features include automated call control and analysis of audio dropouts, call failures, and delays. Integrated GPS capabilities allow for location-specific testing, enhancing the reliability of results in varying environments.
Automated End-to-End Testing
VQuad™ extends the testing capabilities to automated environments across wireless, VoIP, TDM, and analog networks. It utilizes programmable scripts to automate call control, voice transmission, and data collection. When used in conjunction with vMobile™, VQuad™ facilitates comprehensive field-to-lab testing even across geographically separated sites.
Centralized Data Analysis
WebViewer™ provides convenient browser-based access to testing results, featuring both graphical and tabular displays. Users can generate customized reports and export data, while GPS-based plotting enhances the analysis. AutoVQT™ complements these tools by automating high-volume analysis, processing thousands of voice files rapidly, thus streamlining overall testing efficiency.
Integrated Testing Platform
GL’s Voice Quality Testing solutions collectively form an integrated platform for a variety of testing scenarios, including 5G, VoLTE, and VoIP applications. This platform is suited for mobile network benchmarking, automated laboratory testing, and performance analysis, thereby addressing the complex needs of modern telecommunications.
In conclusion, GL Communications stands at the forefront of voice quality testing solutions, dedicated to ensuring the reliability and quality of communication networks. Their innovative technologies not only simplify the testing process but also enhance the overall user experience in voice services.
