Wordle is a free site that lets you input text (such as President Obama's acceptance speech, seen below) and generate a "word cloud." Words appearing more frequently receive greater prominence in the cloud.
This site has five different graphs and charts you can customize for your speeches. Once you choose a graph, you set the design, input the data, and add labels. Graphs can be printed, downloaded/saved, or emailed.
There are two Presentation Practice Rooms located in Hamilton Library's Addition that can be reserved by University of Hawaiʻi at Mānoa students. Each room includes a computer with Microsoft Office, an LCD projector, screen, white board, and worktable with chairs.
