Tone of Voice
It is how the direction of the voice goes from the mouth when pronouncing. There are two main kinds. They are Diffuse and Direct. Naturally, most humans use only one of these two when speaking (only Diffuse or only Direct).
Diffuse: the voice starts spreading out in various directions after it goes from the mouth. It has an easy-listening sound. It can be used in all situations, including informative, persuasive and inspired.
How to use: while pronouncing, try making the voice out along with breath from your mouth.
Direct: the voice goes directly to the audience. It has the power to catch the audience’s attention. It is typically used to keep the audience focused on the conversation, not being distracted.
How to use: while belting the voice out, making the breath from your mouth out at least as possible.
Gestures
It is important to think in advance about hand gestures before public speaking.
Hands must always be visible. Also, pay attention to what you are doing with them.
DO NOT use your hands as you would usually (wringing them, stuffing them in your pocket, playing with your hair, clasping them in front of you, etc). You have to use your hands in a manner that conveys confidence.
Hands are not only useful to convey practical information. It can (and it should) also be used to convey emotion. DO NOT tell an emotional story and expect your audience to feel what you feel if you allow your hands to remain stoically at your side.
When you are talking about important subjects and stating your opinion, you should be extremely careful which side of your hand you are showing to your audience. DO position your hands in a way to be in accordance with your words. To convey the idea that you are open to debate on a topic, people should see the palms of their hands. On the contrary, if you are certain about certain topics or statements, you can be clear about that, by “pressing” your palms in a downward motion as you state that certainty. Palms that move downward mean “case closed” and send that subtle but convincing message to the audience.
Interaction
Public speaking is not just a one-way communication of ideas from speaker to audience; an effective public speaker is one who engages and interacts with his or her audience. Asking questions of your audience, referencing, calling out members of the audience when appropriate, and even just acknowledging and thanking them for their time are all effective ways of verbally interacting with your audience.
Message
Before you stand and speak to any audience, make sure your message is well-defined. Your message – to be precise – is your overall aim, objective, and purpose: the delivery model, audience feedback, and the information transfer.
The repeated mistakes focus on content rather than action. Of course, content is essential, but what do you want the audience to do about it? How do you want them to feel? What action would you like them to take?
You may also have other intentions for your speech as well: the message behind the message. Perhaps you have a singular goal, point, or emotion you want your audience to feel and understand. Every word you use to craft your speech then works to achieve that particular goal, moment, or feeling.
Powerpoint
The first common mistake is to put too many words in a slide. Your PowerPoint is not a Word document. If there are too many words, the public will focus on the slide more than on you. Therefore, sentences should be shortened as much as possible.
Also, it is better not to overload a slide with colors or pictures. Your presentation is not an advertisement or does not have any marketing purpose. The Powerpoint should be a support to your speech, not the focal point of the whole presentation.
Besides, it is necessary to study the meaning of colors, to be able to choose colors that are in accordance with the feelings/emotions that you are willing to convey to your audience. Clashing colors are to be avoided if you want to be professional.
Jokes
Jokes might be seen as the best way to introduce a speech. Nevertheless, this would also show to your audience that your whole speech is prepared. It is the case, but your audience does not need to remember this. Your speech needs to be fluid and natural.
Also, not everybody feels comfortable with the fact of making jokes because it is a direct way of communication. Also, it might not be your personality to make jokes. There is no obligation to make jokes, instead, you could rather be funny, which is something different and easier to put into practice.
Projection
Projection uses the correct voice modulation and projection techniques to deliver your message with an impact. For example, you want to deliberately get your voice up and down at certain times for your message to make sense.
Get excited about what you want to say. Your audience needs to feel that you are passionate about what you want to speak. You will be seen as a believable speaker if you trust your own words. Afterward, many exercises can help you improve your projection, using the chest, the larynx, etc. For instance, bending from the waist down as you sing or speak will help you feel a loosening vibration, which will, in turn, give you that feeling of vocal release. In essence, as a speaker and singer, you want to bounce your voice out of your mouth, not yell and force it out. It is achieved by having a lower and stable larynx and using vowels that shape a particular way that encourages resonance.
Eye contact
Eye contact is the first and most natural way to connect with an audience. However, it can be stressful to look people directly in the eyes. You feel judged on any move or any word you pronounce, and the look of alterity can be heavy. But looking others in the eyes can be turned into another approach: your audience needs support to understand your speech. Looking at them is a means to catch their attention and to make them feel important.
