Final answer:
A literary speech is considered a style of literary nonfiction due to its use of narrative techniques and literary devices to creatively present real-life events and themes.
Step-by-step explanation:
A literary speech is considered a style of literary nonfiction because it uses narrative techniques and literary devices to convey real-life events and ideas in an artistic or creative manner. Literary nonfiction encompasses genres like memoirs, biographies, autobiographies, and literary journalism, where the writing is nonfictional yet employs a narrative structure akin to fiction. It often includes elements such as plot development, character portrayal, setting, theme, and various literary devices like metaphors and descriptive imagery to enhance the storytelling. Literary nonfiction differs from more informational nonfiction by the inclusion of these artistic elements, and the narrative usually maintains an orientation toward telling true stories. The style can be multifaceted and multidimensional to reflect the complexities of real life. While the author and narrator may be the same in literary nonfiction, thus presenting a 'truth', the use of a rich, expressive language and a persuasive or evocative tone is central to engaging the reader and exploring themes more thoroughly.
