Speech recognition accuracy is not great under ideal conditions. Doing 
what you suggest seems unlikely to achieve any meaningful accuracy. 
Speech recognition training systems require many occurances of a word or 
phrase, clearly spoken, before their accuracy becomes useful. A one shot 
utterance from Festival seems to fail on both counts :-)

Bottom line: the very best speech recognition still sucks. As a British 
speaker I never get more than about 40% accuracy speaking into a US 
trained recogniser. I have never had better than about 70-80% accuracy 
on a British trained recogniser. Strangely, my terrible Cantonese gets 
nearly 100% on SpeechWorks recogniser. :-\
