iOS users disappointed by Siri now have a choice. Google (GOOG) on Tuesday showed off some new enhancements to its mobile search application for iOS and Android, including a new voice feature that recites answers back to you just as Siri typically does. What makes this so intriguing is that the app draws on Google’s powerful search capabilities to deliver a wider array of answers more quickly. In other words, using the search app on your iOS device is like having Siri that happens to be powered by Google’s search engine. A short video demonstration of the app’s new voice enhancements is posted below.
