I've watched multiple videos of her "speaking" now. The only speeches that are understandable are the ones that are reenactments - that is, when it's not really her speaking. In the real videos sometimes a few words seem distinguishable, but generally it's not.

She had someone tell people what she was saying, using the excuse "for people with hearing disabilities who would have a difficult time hearing her". Really, it seems more like it's disingenuous.

She is amazing and overcame a mountain, and that's awesome. I still don't believe she was an audible speaker. That's completely fine. Millions of people have non-audible languages as their primary language.
