# Plugin Development

Naomi's core strength is the plugin system. This means that for almost anything you would like to change about Naomi, you only need to write a plugin. Plugins allow you to quickly and easily test a variety of audio engines, speech to text engines, text to speech engines, text to intent engines, voice activity detection engines, etc. without having to change anything in the Naomi core.

Plugins work by defining a standard interface that plugins of the class must conform to. That way they become interchangeable within Naomi.

To make plugin development easier we have created a web based editor that returns a properly formatted framework for a developer to build off of. You can find more information on the NPEeditor here.

Current plugin categories and classes include:

Plugin type	Category	Parent Class
Audio Engine	audioengine	plugin.AudioEnginePlugin
Speech Handler	speechhandler	plugin.SpeechHandlerPlugin
Text to Intent	tti	plugin.TTIPlugin
Text to Speech	tts	plugin.TTSPlugin
Speech to Text	stt	plugin.STTPlugin
Speech to Text Trainer	stt_trainer	plugin.STTTrainerPlugin
Voice Activity Detection	vad	plugin.VADPlugin
Visualizations	visualizations	plugin.VisualizationsPlugin
