You are trying to use a recognizer language with the desktop ASR for which you don’t have the corresponding language pack installed/functioning on your system. If you use Windows 8.x or Windows 7 Ultimate, you can install additional language packs via control panel (Language settings in 8.x or Windows Update in Windows 7). In Windows 10, you have to use the System Settings app to install the speech input module for the desired language (click Time and Language, then Region and Language, then select a language (you may need to add it first), click Options, then click the Download button next to Speech Recognition.
If you don’t have this option, consider changing the DesktopAsrHandler to SpeechServerAsrHandler by replacing the corresponding strings in your configuration file. For the Speech Server ASR, you can download any required language packs from the web (see “Installing the Speech Server ASR”) independent from the OS language.← When trying to use the ASR, I receive the error message “Failed to add connector of type ‘DFKI.Automotive.Audio.ASR.DesktopAsrHandler’: No recognizer of the required ID found. Parameter name: culture (ApplicationException)”.
