How can I make a presentation accessible but low on text?
The flip side is that some people are vision impaired and text won't work for them. You don't need to pass transcripts around, but you can make them available for those who would like them. Some conferences have student workers that monitor the entrance to the speaking hall and they can distribute them at the door. You can also announce at the start that they are available after the talk (or online). Many folks will have laptops open during any presentation. Some people may want to record your talk. 

But it is a good idea not to have slides that are dense with text. For everyone. If people are scribbling down your slides, then they won't be listening to you. 

If you can print only a small number of copies you should probably make them available online as well.
