Google voice search has been what I personally would call, a luke-warm hit on the mobile platform. Taking away from the wildly successful Google411, Google’s Voice Search uses the same tech, despite needing more time for better development in my opinion.
Now there is news of Voice Search coming to other languages such as Russian, Polish and Czech. And this of course means, there will be even more users. With any luck, Google having more people using the product will mean that we will see improved voice recognition and other needed features. As things stand now.
Speaking for myself, I used Google411 way more than Google Voice Search. That said, over time this could change. Assuming the project improves over time and provides me with a compelling reason to give it a second look, I may end up becoming a Google Voice Search fan.
