Your formulation is not clear enough to me. I can guess what it is, please see my answer. If this is not what you are asking about, please try to clarify.

Most voice recognition systems do one of the two things.

1. Recognize a large vocabulary from a small audience (ie. trained to one person).
2. Recognize a small vocabulary ("yes", "no", "one", "two", "three", etc.) from a large audience (male / female voices with regional accents).

They generally don't recognize a large vocabulary from a large audience.

Probably it means that you need to use DictationGramar:

Don't hold your breath: last time I tried it, the quality of recognition was ridiculous, the more the size of the grammar, the more recognition problems — too many similarly pronounced phrases. Not sure about the latest version of the engine; I would not be too enthusiastic. Just try it.
