Q: Enhanced Dictation is not working

Just did a software updated on my Mac Book pro a few weeks ago, and the dictation stopped working.

I press my shortcut keys, and the microphone pops up and the symbol fluctuates showing it picks up my voice, but it doesn't produce any text. It only works properly when Enhanced diction Disabled. I have tried deleting the core diction file, so that when I re-enable enhanced diction, it downloads a new library file, but this did not work!

Please help! I love the enhanced dictation function. (speech is working fine)
