In speaking from a manuscript, a speaker reads from a manuscript rather than deliver it. In this type of speaking, you communicate your ideas extemporaneously, only glancing occasionally as the need arises at your prepared notes. You have more freedom to express your ideas and you can use your gestures effectively.
Speaking from a Manuscript
This type of speaking is not public speaking in the sense that it fulfills the need for verbatim delivery in radio, on important occasions of state, for example: public pronouncements of the government, dedications, etc.
In this type of speaking, a speaker reads from a manuscript rather than deliver it. While this kind of speaking maintains a sense of continuity of ideas, a logical sequence of thoughts, and expresses a sense of security for the speaker, it is not effective as the other types of speaking. This is a speech ready for publication.
This kind of speaking has more disadvantages than advantages. First of all, manuscript reading itself is distracting. In this kind of speaking, you must remove your eyes from the audience, glance at the manuscript, and then, reestablish contact with your audience. Since this act recurs throughout the speech, there cannot be the same close contact with the audience that would be possible in extemporaneous speaking.
In this kind of talk, the manuscript induces mechanical and monotonous reading. The expression of the speaker's personality does not enter into reading as well as it does in speaking. For this reason, there is too much of a break between the getting of the information from the manuscript and expressing it to the audience. Lastly, the audience is less suggestible when listening to oral reading than to speaking.
Speaking with Notes
You will be using this type of speaking in some occasions. In this kind of speaking, you arm yourself with notes to help you remember the points of your speech. This kind of speaking is more advantageous than speaking from a manuscript.
In this type of speaking, you communicate your ideas extemporaneously, only glancing occasionally as the need arises at your prepared notes. You have more freedom to express your ideas and you can use your gestures effectively. For this reason, you can establish closer rapport with your audience than in speaking from a manuscript.
However, this type of speaking encourages faulty preparation. Because you know you have notes to rely upon in your moment of speaking, you do not prepare adequately anymore. You cannot exercise creative thinking, which is the result of inspirational flashes of ideas because you have to stick closely to your notes. For this reason, you lose your spontaneity in the communication ideas.
Too many notes can be disadvantageous to you as a speaker. The notes will stand between you and your audience as you keep on peeping into your notes and such an action interrupts the flow of thought and leads to the distraction of the audience's attention. It also interrupts the movement of the speech, thereby making the rhythmical flow of the speech jerky in nature.
Use this type of speaking with caution as demanded by the occasion.
Speaking From Your Experience and Knowledge
When speaking to an audience, your audience will become more engaged with everything you say if you are speaking from experience and knowledge instead of reading from a script. Knowing your subject thoroughly can really help you get your message across.
If you believe in your subject that you are talking about, your audience will also believe in what you are speaking about. Notes can help you while giving a speech, so you do not forget your points. But otherwise, speaking from experience and knowledge of your subject, everyone will hang on every word.
Whether you are giving a speech to make a point or to sell a product, it is always best to speak from experience and knowledge.
