Although it was helpful collecting the data from the film of the language used on board the submarine I need to create a way for me to learn the phrases myself. I am also worried about my tone of voice, I went to see a voice coach who can help me lower my tone and make it more authoritarian, however it is quite expensive so don’t want to go ahead with it if it’s not definitely the right decision. For now I will try and learn the sub phrases. Copying Crane
