An interresting question might be "How well to humans recognize words in the same situation?" I doubt they can score better then 80%. Sounds low but "same situation" means the human does nt have access to the grametric or semantic context and must recognize the words one at a time in radom order over a telphone. But if you design the application "correctly" and you look not just at the firt pick but the whole probibility list you can do well. Well being maybe 80% or so. So one in five time you have to ask the use to press a key or something. I agree 100%. You will have to get some people together to train the system. ===== Chris Albertson Home: 310-376-1029 [EMAIL PROTECTED] Cell: 310-990-7550 Office: 310-336-5189 [EMAIL PROTECTED] KG6OMK __________________________________ Do you Yahoo!?
