Nuance SDK Helps Developers Add Speech to iOS, Android Apps

Nuance, makers of speech recognition engines such as the Dragon suite for mobile and desktop platforms, has announced that it is offering the Dragon Mobile SDK through a self-service website as part of the Nuance Mobile Developer Program. The SDK will work for developers looking to create iOS or Android apps and will be available to developers through a tiered pricing mechanism.

As part of the SDK, developers can now leverage Nuance’s speech recognition engine and text-to-speech feature in apps. Nuance’s speech technology has been employed in the past on a number of mobile apps on iOS and Android, including popular ones such as Siri, Price Check by Amazon, Ask for iPhone, aisle411, Merriam-Webster,, and SpeechTrans.


The SDK will make it easy for developers to incorporate text to speech into more apps. As platforms now focus on the user experience and apps are moving from a cluttered UI to a more organic natural user interface that’s more intuitive, speech may be the next big thing after capacitive touchscreens. Along with visual interfaces that combine cameras and 3D, speech will help to evolve the user experience on both the desktop and the mobile space. It’d be interesting to see how developers incorporate speech as part of a seamless user experience on existing platforms today.
