 ## API
 
 ### Commands
-This freeswitch module does not add any new commands, per se.  Rather, it integrates into the Freeswitch TTS interface such that it is invoked when an application uses the mod_dptools `speak` command with a tts engine of `google_tts` and a voice equal to the language code associated to one of the [supported Wavenet voices](https://cloud.google.com/text-to-speech/docs/voices)

 ```js
-ep.speak({
-    ttsEngine: 'google_tts',
-    voice: 'en-GB-Wavenet-A',
-    text: 'This aggression will not stand'
-  });
+var text = "Hello World";
+await endpoint.speak({
