Google is working on voice search functions with their GoogleMaps on Blackberries. Now, this is really old news as I have covered Microsoft’s TellMe service which does exact same thing for more Blackberries except using Microsoft’s LIVE search and LIVE maps.
Now, in the long run, I would predict Google win this voice-search race since Google does have better search engine and better maps.
