VQ Bench Call Voice Quality Scoring System
Product Introduction
VQ Bench is a call voice quality scoring testing software designed for the R&D end, integrating third-party scoring algorithms and some standard tests available on the market.
The software, paired with a complete set of hardware independently developed by Megatron, forms the entire testing system. This comprehensive testing system can reproduce noise environments, thereby simulating the call quality of products in real-world usage scenarios within the R&D lab. This assists engineers in evaluating and improving the voice quality of communication products.
Product Details
The software integrates testing, data collection, and data analysis into one. It is composed of four major modules: the main testing module, hardware calibration module, audio configuration module, and Bluetooth control module.
The software conducts all tests and analyses based on international standards such as 3GPP, ITU, and ETSI.
It features a playback equalization module that meets the requirements of ETSI ES 202 396-1 by playing back background noise during testing.
The software has the capability to export test score results and charts to Excel, and it can also directly export all test data for subsequent editing using Office tools, making the presentation of test results more intuitive.
The software allows saving of test recordings as WAV files for subsequent analysis and subjective listening judgment.
It supports offline analysis, facilitating the re-analysis of past test data.

Product Advantages
1. Hardware Openness:
The hardware required for the software, such as sound cards, dummy head-and-torso simulators, and microphones, are all independently developed and manufactured by Megatron, ensuring high stability in testing. The software can be paired with different external hardware to form a testing system that meets the needs of different customers at various high, medium, and low levels.
2.No Copyright Disputes：
The software is independently developed by Megatron, and all third-party algorithms integrated within it have been officially authorized. There is no need to worry about copyright issues when using it for testing purposes.
3.Keeping Up with the Times：
The software is continuously updated, constantly improving existing test items, adding new testing algorithms, and adapting to testing for a wider range of products.
Selectable Test Scoring Algorithms
POLQA (Perceptual Objective Listening Quality Assessment):
POLQA is a new voice quality testing technology based on the ITU-T P.863 standard, suitable for benchmark testing of voice quality on fixed, mobile, and IP-based networks as a global standard. It can be used for voice quality analysis in VoIP, HD voice, 3G, 4G/VoLTE, and 5G networks. POLQA offers a higher level of benchmark accuracy and adds important new features for wideband (HD) and full-band voice signals, supporting the latest voice coding and VoIP/VoLTE transmission technologies. POLQA is highly suitable for evaluating, optimizing, and monitoring the voice quality of next-generation networks, and provides a standardized, verified Mean Opinion Score (MOS).
