Question: How do I convert text to high-quality voice and deliver it to cell phones? Can you provide me with 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: Download the Shout Out app from the app store. Put a URL that can return text in the text box. The parameters for this URL will be the same as for the Passthru applet. Because one of the parameters is the phone number, your URL can return different text for different callers, and the content will be read out using our Text to Speech engine.
