Google announced a download that enables voice search for Google Maps on Blackberry devices. It’s reportedly built on the same speech recognition engine as Goog411. The obvious use of Google’s GOOG-411 service is to add speech recognition to Google’s mobile mapping application. Google started to test Google Maps with voice search for three Blackberry Pearl models: 8110, 8120, 8130 and only for the US. Instead of typing when you want to search for a local business, hold the left-side key, say what you want to find and then release the key. Google Maps Mobile will display the search results on the map.
“Similar to other voice-recognition technologies, the accuracy of voice recognition will improve over time as more people use the voice search feature,” says Google Mobile Blog. In fact, the main reason why GOOG-411 has been developed was to obtain data to train Google’s speech recognition algorithms. “Whether or not free-411 is a profitable business unto itself is yet to be seen. I myself am somewhat skeptical. The reason we really did it is because we need to build a great speech-to-text model … that we can use for all kinds of different things, including video search,” explained Marissa Mayer from Google.
