gTTS integrate with asterisk based FreePBX

[amir-eee]

It will be very helpful for me, if it is possible to integrate with FreePBX Text to Speech Engines module. If possible, please share the steps. I've already installed it in FreePBX (OS: Debian) but how can I get it on Front-panel? Thanks in Advance.
