Memorized Also a bit risky as you may run afoul of a memory lapse which may unsettle the entire presentation. This method may also come across as parroting - stiff and artificial. Extemporaneous Planned and practiced, the extemporaneous speaker uses a few note cards for reference, but nothing is completely written out. Good for shorter presentations - the extemporaneous delivery allows for greater flexibility, and more spontaneity within the framework you provide. Be aware of reading, look up from the paper and use voice inflection and facial expression to key the audience on certain points.
Papers take longer to present so be aware of losing the audience.
Try to create interest through enthusiasm and confidence. Be sure the audience understands the main point s through repetition and detail. Use visual aids. Be sure the visualize are easy to see and read and the information can be easily interpreted. Do not display visualize until you are ready for the audience to see them - position yourself so as not to block , or talk exclusively to, the visualize.
