A little left field, but I'm trying to train a speech recognition program and the guidelines suggest that I attempt to speak clearly but naturally. I notice, however, that when one speaks naturally each word tends to drift into the next, resulting in a rather ambiguous boundary between the words.

One the one hand, speaking in a more stilted manner would seem to aid the computer in recognising the phonemes, but on the other it would tend to make it less likely to understand more natural speech.

Anyone knowledgeable in the field out there who can suggest which of the two approaches is more effective?

Thanks
