THere is search+a+e that toggles earcon, but we need a third-option (see #2 below).

cvox2 makes extensive use of earcons, so I think the main change would be a verbosity setting that would impact roles and states and have 3 options:
1. earcon+TTS (default/current)
2. Earcon-only
3. TTS-only

It's the first option in the options page: enable verbose descriptions.

I believe I have that option checked, but I will play more with that when I
get home... either way, I believe that this setting ought to be made
available as part of the earcons option as was suggested above. If not,
then the verbose option should be changed to provide more of a description
of what it actually does. When I think of verbosity, I think of controlling
whether attributes are automatically read out in documents or in dialog
controls. I don't immediately think of whether links, buttons, checkboxes,
lists and tables are or are not announced on the web.

Thanks.

Thanks for the feedback. I'll respond to each option in turn:
1. earcon+TTS (default/current)
n/a
2. Earcon-only
Not all roles and states have earcons
3. TTS-only
This is equivalent to turning earcons off

Verbosity is wording historically used by ChromeVox. It not only omits speaking roles, but it also skips some contextual announcements. I'm open to suggestions for making this setting clearer.

I guess I would wish for a way to have a mode to have only earcons enabled
with the exception of those roles that do not have earcons, and for those
to possibly get earcons later. It seems to me to be too verbose to hear the
element type and the earcon all at the same time, but from what you are
saying, setting verbosity option to unchecked should eliminate this? If I
don't have the option checked already, I will check it and provide feedback
if needed.

That's right. The option is labelled
"enable verbose descriptions"

Verbose descriptions are on i.e. checked, by default.

Not all states have a natural mapping in terms of earcons. We try to strike a balance between more earcons and practicality. In most situations, the arcon set covers the most common controls and states are read. To go to either extreme would require someone take a while to learn.

Thank you. I thought I had the option set properly, however it must have
gotten checked in all of my reflashing. This is great. I do think that an
even less verbose mode where headings and heading levels are heard with
different pitched clicks or something would be great, bit this is pretty
good as is. Thank you for prompting me to unchecked that option again.
