Dashboard Enhancements

The LumenVox Dashboard includes new enhancements to its existing monitoring capabilities. These updates put more control in the hands of our users when monitoring their system and process performance history. Users can now set custom times span and scaling options, allowing them to get a general sense of their overall system performance when viewing 10 hours or more, or much more detailed information when viewing time spans set below 10 hours.

This scaling is necessary since the Dashboard can also keep track of and display data for more than one day, which was a limitation in the 12.0 release. Like the rest of the Dashboard, these graphs are web-based and can be viewed on any operating system with a web browser, meaning users can keep track of their systems from a desktop or mobile device.

Grammar Complexity Scores

For years developers have been struggling with how to factor grammar complexity into system sizing and performance. Starting with LumenVox 12.1, the Speech Tuner can calculate a “complexity score” to gauge relative complexity of grammar files and help developers and system administrators make informed choices about grammars and hardware sizing.

Additional Updates

To further help system administrators, the LumenVox software has a new configuration option that allows administrators to specify the maximum number of channels of ASR or TTS they intend to use. The software then intelligently sets a number of other parameters to optimize its performance to meet that need. This takes away the guesswork and trial and error that previously went into finding the optimal configuration settings.

In secure mode, which is used for high-security environments such as those which must meet PCI or HIPAA standards, LumenVox now suppresses additional information from log files. This information includes details about grammar names and content, which should improve privacy for users with sensitive data.

LumenVox version 12.1 is currently in general availability and can be downloaded as always from In order to be eligible to download and use the software, customers must have a current software maintenance contract.
