what is your project about and what does it do?
A soliloquy<span> is an utterance or discourse by a person who is talking to himself or herself or is disregardful of or oblivious to any hearers present (often </span>used<span> as a device in </span>drama<span> to disclose a character's innermost thoughts). If there are others on stage, it is a protracted aside.</span>
