I wouldn't memorize. If I want to read something, I'll use a refreshable braille display or printed out braille. Often I just improvise though since I"m good at that and will use note cards if needed. If I'm delivering a powerpoint, I've used a Bluetooth headset to hear the slide that I am on.

The stories I've told and panels/talks I've been a part of were all done from memory, just going in confident in the topic, some bullet points memorized to hit on in the stride of the talk or conversation, then I wing the rest. I've actually found it a lot easier to talk in front of large crowds since I can't see them anymore.

Hi. I usually give speeches from memory. If I have to follow a PowerPoint, then I have a list of the slide titles to keep myself oriented as I move through the presentation. I never read a speech word for word because it tends to sound robotic, unnatural, and over scripted.

I use little notations to help me go through everything.

Neither. Any skilled speaker, sighted or not, would not memorize an entire speech or read it word for word.

A bit of both. Memorizing helps though.

I mostly memorise. I have some sight so when I don’t have enough time to totally memorise I have an iPad that acts like a prompt card (it throws up a single word in large print to jog my memory)

Some of my friends who have no working vision use a single ear piece and have their device prompt them.
