Anywhere there is a search bar in the app, users can click on the oneSearch button to activate voice controls. Users speak their voice query, it is sent to Yahoo’s server, and then an answer is provided with links. Users can also use their voice to add topics of interest. The voice control technology is powered by Vlingo.
Yahoo is playing catch-up with rival Google, which released a voice-powered search app for the iPhone last year. Google’s app also has an advantage over Yahoo’s because it enables the user to activate the voice search by bringing the phone to the ear. This was made possible because Google utilized application programming interfaces that are generally not allowed by Apple.
