On its own, a spoken tutorial, such as a video that you watch, is not going to give you enough practice speaking and hearing English as a live conversation with an English speaker will. If you're looking to brush up on vocabulary and speech patterns in spoken English, it will meet those needs.
In my experience, some of the best spoken tutorials for English are from "Speak English With Vanessa" https://www.youtube.com/watch?v=2a0SNJrp5MY&feature=youtu.be and from "Go Natural English" https://www.youtube.com/user/GoNaturalEnglish/videos.
