Bad Audio with the GoPro

Watching over the footage I have and it seems that the footage I collected lacked good audio and therefore to fully narrate what is currently happening in the film I will be using subtitles. This may help engage the audience more. However an argument would be that the audience will be too focused on reading the subtitles instead of watching the video. Nevertheless, I don't know any other way to help alleviate the lack of narrative.
