NEW YORK, April 4, 2013 /PRNewswire/ -- At the AT&T* Innovation Showcase , the company today announced the availability of two new APIs: an Advertising API and an In-App Messaging from Mobile Number API. These new APIs are available in the AT&T API Platform and enable developers to integrate ad-revenue streams and add innovative messaging functionality.

In addition, AT&T also announced enhancements to its Speech API, powered by the AT&T WATSON(SM) speech recognition engine, providing developers with speech-to-text and text-to-speech capabilities.

AT&T Advertising API

The Advertising API is a cross-platform, cross-carrier API that allows developers to monetize their apps with in-app, paid advertising, offering an 80/20 revenue share that is driven by the number of advertisements a user clicks.

With the Advertising API, developers can:

AT&T In-App Messaging from Mobile Number API

In-App Messaging from Mobile Number is a RESTful API that enables developers to integrate message functionality in a new way. Using this API, developers can create experiences that let users send text and picture messages from their AT&T mobile number without exiting the app, helping lead to more engaged users. Having the messages sent from an AT&T mobile number allows friends and family to easily recognize the sender, improving the in-app messaging experience.

AT&T Speech API

AT&T has enhanced its Speech API to optimize speech recognition performance through additional speech contexts that are tuned for gaming and social media apps. It also offers a generic context, which can be customized for certain words used specifically within the app. This capability makes the context perfect for command-and-response apps, or those in which app users only say a limited set of words or phrases.

In addition to offering speech-to-text capabilities, the API now offers text-to-speech, supporting both English and Spanish languages. Developers can simply send text as part of the API call, and that text will be read back by a voice of the developer's choice.

"AT&T is dedicated to helping developers achieve success and remains committed to providing this community with the cutting-edge APIs needed to help them bring innovative solutions to market quickly and easily," said Carolyn Billings, Associate VP, AT&T Developer Program. "By enhancing and adding great new APIs to our Platform, AT&T is creating a win-win for everyone involved -- developers are able to enhance their customers' app experience while enjoying new revenue streams."

To assist with implementation, AT&T offers software development kits (SDKs) for these and all APIs on the AT&T API Platform. For more information on the AT&T Developer Program and the AT&T API Platform, visit developer.att.com.
