In addition to the tweet text, it is possible to post a tweet with an explanation in the image. However, it is possible to reproduce explanations by using external assistive technologies such as text-to-speech service instead of being displayed on tweets.

I also looked at the tweet detail screen, but the description of the image was not displayed.

Note that the image description function is for third-party Twitter clients,REST API and Twitter CardsBut it is available.
