Messagebus Wakeword not working?

Is there a native method for using emitter inside a skill (as the name of the code flavor tab ‘Generating Message from MycroftSkill’ implies) or do I need to use a 3rd party package such as this: GitHub - JarbasAl/local_listener: WIP - local pockesphinx listener for mycroft

According to this the Docs are all old on the use of ‘emitter’ and should be changed to ‘bus’. I did this and is no longer throwing an error on ‘emitter’
