GAITHERSBURG, Md., Oct. 18, 2022 (GLOBE NEWSWIRE) -- GL Communications Inc., a global leader in telecom test and measurement solutions, addressed the press regarding their new Voice Analysis Tool (VAT™) which analyzes the audio content within any Narrowband (NB), Wideband (WB), or Super Wideband (SWB) PCM audio file and generates a variety of audio metrics including Frequency Bandwidth, Speech Activity, Active Speech Level, Noise Level, DC Offset, and RMS Power.

GL’s VAT™ operations are fully automated by detecting the audio files within a user-specified directory and analyzing same as the files appear. Using configuration settings associated with the Degraded voice file name, the VAT™ can specify which tests to run, specifies the configuration for each test, and associate the Reference file for tests that require both Degraded and Reference files.
“The GL VAT™ application can generate a variety of audio metrics including Round Trip and One Way Delay measurement, Audio Dropout analysis, Double-Talk measurements, and Voice Quality Analysis (when also coupled with the GL VQT POLQA solution). In addition, the GL VAT™ supports Speech to Text analysis with pass/fail when coupled with the GL Speech to Text Analysis solution,” said Robert Bichefsky, Director of Engineering at GL Communications Inc.
He further added, “All the VAT™ associated results are sent to the GL WebViewer™ central database and can be accessed using the WebViewer™ web browser. If the network connection is lost between VAT™ and the database, the data is saved internally. Once the network connection is re-established the data is automatically sent from the VAT™ to the GL WebViewer™ database, so no data is lost.”
