Re: Use of live regions for announcing additions anddeleteions

Very true, multiple firings of the Alert role will cause anything announced before it to be interrupted, so alerts in general should only be to convey very important information at one time.

Though less severe as Alert, the use of aria-live="assertive" will sometimes interrupt speech on some devices too, so this is important to keep in mind as well.

If you need to have multiple contiguous messages announced in succession, aria-live="polite" should be used.

Hi Rob,

The various screenreaders might treat two alerts firing off at once very differently, so you may want to avoid this approach. Just to be sure the messages are read in the order you want, you could choose not to give the second region a role of "alert" and set its aria-live value to "polite".
