Here are some screenshots from location app utilizing voice searches to find your (points of interest)
You can give the app a POI such as find starbucks and it will show starbucks in your immeadiate area using reverse geocoding, or you can give it an address such as 1600 pensyvania Ave Wash DC and it will use yahoo api to show the exact poi on a google map.
