Hi Julie, In that case, what you might consider is adding a “how to use this publication” section to your frontmatter and inform users there that they will need the additional tts languages for an optimal reading experience. I’ve seen publishers do this for other accessibility issues, like unique tagging practices they’ve used, but it would also fit for this case. That’s if you have the ability to add additional frontmatter, of course. Also, make sure the accessibility summary isn’t repeating the other accessibility metadata, including any conformance statements, if you need more space in it. It should only be used to inform users of information they can’t get from the other accessibility metadata. W3C has published a display guide[1] that covers presenting accessibility information to users, so you don’t want the summary duplicating what will get displayed anyway. (Thorium, VitalSource, and others have, or are in the process of, implementing support for displaying these statements).

I've looked into them, but I'm unsure if they would work with what we are trying to do. Maybe some more context could help: our books are primarily English or French with many of them having several instances of foreign languages, often with repeated phrases, or names with diacritics. We declare the primary languages but know that certain readers like Thorium don't have many available TTS languages, so even if they recognize language shifts tagged with <span xml: lang="">, these can be mispronounced if the reader does not have the language downloaded on their OS. We've put a lot of time and labour into language tagging our accessible titles and want to make sure a reader has all the information available to properly read these books. I am searching for a way to let readers know which languages were used even if they are not the primary language. I know DAISY recommends that dc:language tags only be used for primary languages---does anyone know about an accepted standard for secondary languages other than the above <span>? But maybe this is not possible and using dc:language in a way other than it was intended would be the safest bet or we need to find another work around. Thanks again!

That sounds much more informed. :) I just went and read some of those docs for some context since I didn't understand the crossover between the different metadata syntaxes.

Our copyright pages are already quite long and we wonder if readers just skip over them anyways and would miss the information. We have a 1,000-character limit in the accessibilitySummary field which is already getting quite long and would be restrictive for those titles which have over ten languages being used. Would love to hear from anyone about thoughts on this.
