The Nuance automatic speech recognition (ASR) engine has been upgraded from 9.0 to 10.5, which offers improved accuracy, additional customization, and Nuance support. Over the past year, you've had the option to upgrade your IVR applications to the new ASR engine - which entails updating confidence values of ASR Studio actions and potentially recompiling custom grammar files. If you haven't already updated the confidence values of your ASR actions for improved accuracy, NICE inContact will automatically update the values with the suggested defaults and point directly to the Nuance 10.5 ASR engine. If your system uses custom grammar files, you must recompile the files with the 10.5 engine to make the files compatible.
