Google has added the 'Search by Voice' feature to the latest mobile version of Google Maps for Windows Mobile and Symbian S60 devices. Previously the option was only available for Android and BlackBerry handsets.
Search by Voice lets users search Google Maps by opening the application, pressing their phone's 'call' button and saying what they're looking for. The service supports places, addresses, types of business and specific business names. A 'British English' option is available, along with other languages and accents.
