Custom Recordings If you would like to use your own voice recordings or voice messages recorded via the Record block, use the <url> markup to specify a file for us to use.

To enable us to cache your file locally for subsequent calls, please include the "Last-Modified" HTTP header. Subsequent calls will not have the delay if we are able to cache your file. If you have updated your file, make sure your file hosting web server respond to our HTTP header "If-Modified-Since" in our request with a "304 Not Modified". |

Documentation
You can use the Play block if you want to play a voice message. Our Text-to-Speech service will automatically generate the voice recording for the message you indicated in your API request.
The Play block will first play the message then send a notification to your notify_url. You cannot use this block after you have used any of the End blocks (Transfer, Hangup).
