Trigger Condition

Hi, I'm fairly new to StoryLine and still trying to get a good grasp on the tools. 

I've created a tutorial that has audio on the slide. I don't want the view to be able to advance to the next slide until the audio is finished. Is there a way to control the functionality of the next button on the player itself? 

I know I could add my own next button and simply not make it appear until the audio is finished but I want to use the player buttons. 

I'm guessing it has something to do with Trigger Conditions but I'm not sure what. If there is already a tutorial about how to use this feature, please direct me there! 

Thanks!
