Hi again,
It is a possible reason. When it reads a post, it reads first the title if present and then if there is an image next, like we have for all of our blog posts, it reads the alt. So, we generally set the alt as the post title. When Polly reads the post it will read the title and then the alt, which in our case is the same. I disabled the titles in our posts to prevent this. You can hear the difference in the recording made before I turned off the title at

Compare this to a post I edited, thus forcing Polly to record again. It eliminated the title, and says the post name only once because it reads the alt. See here:

If I had a preference I would rather have my post titles present, and it not read the alt. Also, I have a number of images throughout the post, and it interrupts the narrative every time to read the image alts. So, a helpful option of the plugin could be to have a checkbox to read or not read image alts.
Thanks for your response.
