Resolving Lag With Jaws in an HTML Application Element Using Aria Live Regions

Hello,

If there is a better place to send this, please let me know. I am
developing a web application to work with Jaws.

I am wondering how to remove the strange lag with Jaws sending keys to an
application and Jaws failing to clear aria live region text from its
buffer? On our application site:

https://www.audiom.net/embed/6?apiKey=b_e0xbMW4_hk9tDtOYMrZ

1. Using Jaws, arrow down to “Audio Map On” and hit enter. This will
pop you into application mode. Now hit backslash “” and it will use your
screen reader rather than web TTS.

2. Now press the down arrow repeatedly. There is a 50-100ms delay
between each key press that vanishes when using NVDA or no screen reader.

3. Go to coordinate 35, 17 on the “long ramp” and quickly repeatedly
arrow to the right until the sound changes. You will hear “long ramp” still
announced when you hear the sound change when using Jaws (if you press the
right arrow fast enough). Using web TTS or NVDA, there is no problem
clearing the buffer, and you hear "empty space" right away.



I’m wondering if you have any ideas on how to resolve these usability
issues with Jaws in a browser application?

Our Jaws users are quite unhappy with these bugs, and I don’t know how to
resolve them, especially since they are not present outside of Jaws. I’m
using Jaws 2023 in the latest stable version of Chrome.

Thank you,
