Texture change on voice command?

I am looking for a script that will anable me to change the texture on a single face of a number of unconnected prims with a voice command...

Ideally it would have a wildcard so that I could say something like: " /99 Red* " and the Red01 texture would appear on the first one, the Red02 texture on the second etc.

Any such script around?

I would be interested in any other suggestions of course...

Thanks
