When trying to use the Speech Server ASR/TTS, I receive one of the following error messages: “Failed to locate connector of type ‘DFKI.Automotive.Audio.ASR.SpeechServerAsrHandler’: Type not found or TypeLoadException.” / “Failed to locate connector of type ‘DFKI.Automotive.Audio.ASR.ServerTtsHandler’: Type not found or TypeLoadException.” / “Retrieving the COM class factory for component with CLSID {…} failed due to the following error: 80040154 Class not registered”

Probably Speech Server is not working correctly.

  • Make sure the runtime and the language pack(s) are installed and that you have selected the 32-bit version of Speech Server and (if applicable) of the voice / recognition engine (even if you are running a 64-bit OS).
  • Alternatively, change the Audio Manager configuration from SpeechServerAsrHandler to DesktopAsrHandler or from ServerTtsHandler to DesktopTtsHandler. Whether this works depends on your OS version, OS language, installed language packs, and grammar language.
  • See the section on SAPI ASR and TTS plug-ins in the Audio Manager documentation for more details.
