Question: How do I convert text to high-quality voice and deliver it to cell phones? Can you provide me an API for such a  task? These text messages would be different for different customers.

Solution: You may use our "Shout Out" app to create bulk IVR call campaigns in minutes. Simply choose a list and the message to play out and schedule the time to Shout Out!

Here's how: Install the Shout Out app from the app Bazaar. In the text box, put in a URL that can return back text. This URL will receive the same parameters as the Passthru applet. As phone number is one of the parameters, your URL can return back different text for different callers & the content will be read out using our Text to Speech engine.
