Problem with speech


After using speech recognition for just once, I had a problem with it right after I restarted my 1.5 g4 powerbook.There are no more commands in the speech commands window, despite there being files in speakable items folder. Speech recognition just doesn't work any longer, not even a "what time is it?" What is going on here? I tried making a new user, where it started to work again, but then after a restart, it disappears again. Any users with the same problem care to share? I have tried to re-install tiger, but no difference. Thanks in advance.
