Every new build of macOS 26 further breaks some part of text-to-speech or voice control. I have filed multiple bug reports on this, yet the situation gets worse, not better, with each new build. I am begging you to fix this! I am disabled and rely on these features to work. Accessibility in macOS is more than 50% of my reasons for choosing Macs over Windows.
Here's some of what is currently broken:
Speak announcements only works if the Samantha voice is selected. If other voices are selected either the announcements don't speak, or they default to the Samantha voice. This became broken with 26.1.
Announce the time only works with some voices. I would like to use Australian English Siri 2 but with that voice selected it defaults to Samantha. This became broken with 26.4.
With voice control enabled there are two menu bar icons. The blue voice control icon and an orange microphone "an application is accessing the microphone" icon. This orange icon started appearing with 26.3. For four years of macOS releases, the orange warning didn't apply to system services. And note that with voice control enabled on iOS there is no orange icon. It wastes valuable menu bar space and defeats its purpose. With that orange icon always being there I have no indication if a nefarious app starts recording me. This became broken with 26.3.
Overlay shows numbers even when it is set to none. This has been broken since at least 14.0. I don't remember if it was broken in prior versions but it has been broken in every version since 14.0.
The voice control control center widget is defective. If voice control is not in the menu bar (for example if I've said "Siri turn off voice control") using the control center widget to turn it on brings about the orange icon, but not the blue icon actually used for controlling voice control. If you do have the blue voice control icon and use control center to turn off voice control the blue icon stays but voice control is not enabled. This became broken in 26.0, was fixed in 26.2, broke again in 26.4.
When using voice control to edit text (aka dictation mode) saying "go to the end of the line" invariably goes to the beginning of the line. Once in a blue moon it will go to the end, but there is no rhyme or reason and it's rare that it does. Since this bug was added it has worked correctly exactly twice. This became broken in 26.3 (possibly 26.4).
I know I am missing some issues. Voice control and text-to-speech have new bugs with each new build of macOS 26. My main Mac is being repaired and once I get it back I'll be installing macOS 15 Sequoia on it because of these issues. These issues stop me from buying a new Mac because any new Mac will only run the broken macOS 26. I file bug reports on each build when I discover another new issue, but these reports seemingly go unread.
I would suggest Apple get a focus group of disabled people together and do research into how we use macOS. Find what's broken and what works. And if Apple does this I would be glad to be a part of that group. My place, or yours. Accessibility at one time was something Apple was proud of. It was some Apple showed off. But now, I'm not so sure. It's starting to look like Apple doesn't care. I hope I'm wrong, and that Apple does care, so...
Please, Apple. I am begging you. Fix broken Text-To-Speech and Voice Control!
