Six years later, Google Mobile App for iPhone introduces the same feature, but this time the search results are displayed in the same application. Google built a sophisticated platform for text-to-speech and speech recognition using data from GOOG-411 and we can already some of its applications in Mobile Google Apps, YouTube and in this updated iPhone app.
It's quite weird to say how to download the app: since Apple doesn't offer user-friendly permalinks, you'll have to visit the iPhone App Store and search for "Google Mobile App". This iPhone app is just a sneak-peak into the future of mobile search, which will become more intuitive and easier to use.
"In the next 10 years, we will see radical advances in modes of search: mobile devices offering us easier search, Internet capabilities deployed in more devices, and different ways of entering and expressing your queries by voice, natural language, picture, or song, just to name a few. It's clear that while keyword-based searching is incredibly powerful, it's also incredibly limiting. These new modes will be one of the most sweeping changes in search," anticipates Marissa Mayer. She even envisions a "wearable device that does searches in the background based on the words it picks up from conversations" to illustrate how search will become a part of our life.
