Goog-411, Google’s voice driven 411 directory assistance that uses the same business listings and rankings as Google Maps, has recently been upgraded to only require a single business + city search phrase. This upgrade mirrors the late July blue line upgrade to Maps that moved Maps from a two field entry (one each for business and location) to a single single search box like the main Google search page.
Goog-411 now starts the search with the phrase: Say the business and the city and state…If that query is not understood the service reverts back to the requirement to entry first say just the city and state. Once that query is answered it then notes: What business name or category?. While it is not noted the user can still ask for category + city during the first query combined query.
