SharePoint 2010 Search

You most probably know by now that SharePoint Server 2010 will use a lot of the FAST search technology. I don't know much about FAST so I was surpised to hear of a couple of the new features that may appear.

1. Visual Search
   I guess you select or upload an image and it will go and find similar pictures.
2. Conversation Search.
   Audio file is uploaded, speech to text translation takes place allowing search to find words in the file.

How is Conversation Search going to work? If I search for a keyword that is in the audio multiple times will it indicate each time the word is used and allow me to go to that part of the audio?
