The academic style: This style characterizes lectures, scientific discussion, conferences, classes to entertain. It is used to deliver this message to the audience, to establish a contact with the listeners. The speaker must sound self-assured, authoritative, instructive. Terminal tones are compound, there is a great number of high categoric falls, the contrast between accented and nonaccented segments is not great. Loudness may be increased, sometimes strongly, pauses may be prolongued, rhythm is organized properly, especially while giving the rules, reading them, drawing conclusions (scansion). The acoustic impression of rhythmicality is present.
