A Study of the Language Characteristics of Types of Business English Speeches from the Perspective of Functional Linguistics

Business English speeches are an essential form of business communication, and the question of how to improve their effectiveness is essential to successful business communication. Based on a self-built corpus of Business English speeches, this paper studies the relationship of sentence structure, business vocabulary, and speech type with business speeches by using a quantitative statistical method. It reveals that the sentence structure used by the speaker changes according to the content and type of speech, while the proportion of business vocabulary relative to the type of business speech stays at a low level of 5%, with little variance. Sentence structure and the frequency of business vocabulary should be adapted according to the type of speech so that positive effectiveness can be ensured.
