On speech control panel launch: "The requested task cannot be carried out because the necessary engine could not be created. Please select a different engine and/or a different audio device." Any ideas? Registry fixes especially welcome, as I don't know what else is left to try. I tried: 1. Uninstalling and reinstalling office. 2. Removing windows\speech, and files associated with it, and then reinstalling. 3. Uninstalling/reinstalling Microsoft Text-to-speech sdk 5.1 4. Reinstalling the speech control panel and ms agent components.
