The gestures should be used to keep your speech on track; it concisely states what your speech is trying to demonstrate.
More about gestures:
Gestures mean using a body movement, probably a hand or a head, to express something beyond words. Gestures are an important part of a speech, they help in a broad understanding of what the speaker wants to convey. If the speaker does not use body movement and simply speaks everything in one go, the listener gradually starts losing interest and the session will become boring. Therefore, it is advised to use gestures and add humorous content in a speech to make listeners associated. It also helps to win an edge over the competitors.
