 # How To Change Your Assistant's Voice
 
-**WIP**
+## Using TTS server plugin
+
+### General
+TTS server plugin is using services hosted by OVOS community:
+https://openvoiceos.github.io/community-docs/325-members/#members-hosting-services
+
+That reduces local resource consumption. Its recommended to use TTS server plugin for resource constraint hardware (eg. RPi 3)
+
+> [!NOTE]
+> You can host TTS server by yourself - check this [blog post for details](https://blog.graywind.org/posts/piper-tts-server-script/)  
+> The post is specifically for running Piper TTS, but could also be adapted to run [other TTS plugins](https://github.com/orgs/OpenVoiceOS/repositories?language=&q=tts-plugin&sort=&type=all).
+
+### Changes 
+Open the file for editing.  `nano ~/.config/mycroft/mycroft.conf`.
+
+If your file is empty, or does not have a `"tts"` section, you need to create it.  Add this to your config
+
+```json
+{
+    "tts": {
+        "ovos-tts-plugin-server": {
+            "voice": "amy-low"
+        }
+    }
+}
+```
+
+For available voices please refer to [piper-voices section](#voices-available-for-piper-plugin)
+
+## Using local piper plugin
+
+### General
+Local piper plugin does all Text-To-Speech translation on your local device.
+
+### Changes
+Open the file for editing.  `nano ~/.config/mycroft/mycroft.conf`.
+
+If your file is empty, or does not have a `"tts"` section, you need to create it.  Add this to your config
+
+```json
+{
+    "tts": {
+        "module": "ovos-tts-plugin-piper",
+        "ovos-tts-plugin-piper": {
+            "voice": "alba-medium"
+        }
+    }
+}
+```
+
+For available voices please refer to [piper-voices section](#voices-available-for-piper-plugin)
+
+> [!WARNING]  
+> After a configuration change it's important to reload the audio service.
+> (an example used with systemd services `systemctl --user restart ovos`)
+>
+> If your system is not using systemd - please refer to [relevant documentation](051-starting_modules.md)
