The definitional speech may pertain to the physical attributes of a phenomenon. The starkest differentiating aspects about a subject constitute a definition of speech.

Descriptive Speech: 

A descriptive speech may be confused with a definitional speech. It provides a detailed and elucidate description of the subject in question. The description is just a broad-gauged account of the basic definition of the subject. You can start by providing essential information about the phenomenon or the object, followed by its characteristics. A descriptive speech also delves into the impact of the effects of a particular phenomenon.

Explanatory Speech:

An explanatory speech provides a complete description of the variegated aspects of a topic. It explains the underlying rationale behind theories and puts forth their theories in detail. Explanatory speech is ideal for academics to explain rudimentary aspects of a subject. Where there is a requirement for explaining the essential elements of a topic, an explanatory speech is an ideal way to go about the task. Explanatory speeches are based upon the understanding that the audience must be able to understand the rudimentary rationale behind the working of a mechanism.

Demonstration Speech:

A demonstration speech can be a great way to help a reader understand how technology functions. A demonstration speech puts forth a simple step-by-step and understandable account of the various topics in question. These speeches are ideal for providing the readers with an explanation of how tech applications work.
