The binaries are currently available for the following Linux distributions:

  • Red Hat / CentOS 7 (unimrcp-gsr-1.7.10-1.el7.x86_64.rpm)

This release provides a few improvements and fixes.

The detailed list of changes introduced in this release follows.
New Features
  • Added support for sorting result alternatives based on confidence score (the highest first).
  • Made separator of built-in grammar parameters configurable.
  • Set the SSL security level to 1 by default. This setting applies to the use of the license server on Ubuntu 20.04 and does not affect other supported distributions.
Fixed Problems
  • Fixed a possible memory leak occurred when two file entries (waveforms and/or RDRs) have the same creation time, which is a very rare occasion not involved in the regular operation.
Configuration Parameters
  • Added a new attribute 'sort-alternatives' to the element 'streaming-recognition'.
  • Added a new attribute 'grammar-param-separator' to the element 'streaming-recognition'.
  • Added a new attribute 'security-level' to the element 'license-server'.
Miscellaneous
  • Updated the Usage Guide to reflect the changes introduced in this release.
