 # mod_google_tts
 
-A Freeswitch module that allows Google Text-to-Speech API to be used as a tts provider.
+A Freeswitch module that allows Eleven Labs' Text-to-Speech API to be used as a tts provider.
 
 ## 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)

 ### Events
 None.
 
 ## Usage
 When using [drachtio-fsrmf](https://www.npmjs.com/package/drachtio-fsmrf), you can access this functionality via the speak method on the 'endpoint' object.
 ```js
-ep.speak({
-    ttsEngine: 'google_tts',
-    voice: 'en-GB-Wavenet-A',
-    text: 'This aggression will not stand'
-  });
+var text = "Hello World";
+await endpoint.speak({
+    "ttsEngine": 'elevenlabs',
+    "voice": "W9OIfHh5DtdYiZUcFiql",
+    "text": `{use_speaker_boost=1,optimize_streaming_latency=4,style=0.5,stability=0.5,similarity_boost=0.75,api_key=XXYYZZ,model_id=eleven_turbo_v2}${text}`,
+});
 ```
