Long before Siri could answer your questions about the weather, Android featured native text-to-speech recognition. The functionality made the mobile operating system more accessible to those users with hearing or speech impairments, and the feature made it a cinch to perform activities such as texting a friend while driving. In Android 4.1 Jelly Bean, Google introduced offline voice dictation, which allows Android to turn your speech into text even if the device isn’t connected to a network.
Plenty of third-party apps now use the native speech-to-text engine as an alternative means of input. The underlying technology has helped to make features such as Google Now a success, and you can even see its capabilities in the Moto X’s always-on listening feature.
