Google Voice search was available as a standalone application for Android phones, however it’s now integrated into the search bar and is a feature in Google.com . This feature is available in US at the moment, not sure when it’ll be rolled out for other local search engines yet.
You’ll see a small microphone symbol within Googles search bar, pressing it will start recording your voice and the content you speak will be used as ‘Search Query’.
The accuracy is higher when you speak with the microphone held close to you, and also I noticed that it kinda shuts down Chrome (as I’ve tested it only on Chrome as of now), when you speak a lot of content, what I mean is, if the search query is too long the browser kinda hangs.
I’ll verify this in sometime and update if it was just a coincidence that my browser hung up on me, or if it’s a real problem with the new ‘Google’s Voice Search’. It’s possible that it might just be a browser issue or my internet service provider issue that’s acting up on me. I’ll verify this in sometime and report back again.
Till then, I guess you can enjoy the ‘Voice / Speech Search’ Google’s offering
