Macromedia Flash / Voice activation

At school we have an another project going on to make a certain application, how it should work of what it is, is totally open. Since a few days I’ve been searching on Google and another search engines to find something about Flash en voice activation or at least a way to do interaction in Flash with your microfone and it’s sound input.

My question is, is here someone who knows more about this subject and/or resources where I could study from how to archive such things?. :smiley:
