Excerpt from Google Mobile Blog:
You can now search Google Maps for Android using your voice, making it easier than ever to look up places while on the go. Whether you’re searching for an address, a business, or nearby windsurfing spots, just speak your query and Google Maps will find it. Our voice recognition engine currently understands English in American, Australian, and British accents. After you search, you’ll see a map of places. To help you decide where to go, we’ve improved our business listings to include content such as store hours, prices, ratings, and reviews.
We also added transit and walking directions to Google Maps for Android. You can now get directions using public transportation in over 250 cities, including New York City and San Francisco. If you’re looking for the best route on foot, use walking directions to take advantage of pedestrian-only pathways and to avoid one-way restrictions.
