Prefer ENGINE-ID globally while preserving explicit voice routes.

By default the change lasts for this Emacs session.  With prefix argument
SAVE, atomically save it in the active routing profile.  Remaining engines
keep their relative order; explicit logical-voice routes and fallback policy
are unchanged.  When no profile has been saved yet, the live adapter policy
becomes an in-memory baseline; SAVE explicitly persists that baseline.  The
command does not stop speech already playing.

(fn ENGINE-ID &optional SAVE)

Clear the temporary preference and restore the saved or initial order.

Open the accessible Voice Workbench in VIEW.

(fn &optional VIEW)

Restore the exact profile snapshot from when the workbench opened.

Clear all physical-voice filters and refresh.

Compare the selected physical voice with another matching voice.

Display and speak exact Workbench row and configuration details.

Edit the common Voice Workbench comparison text.

Show speech engines and their capabilities.

Export the staged routing profile without activating it.

Find a voice by name and reveal it across collapsed language groups.
Search respects engine and explicit filters.  If the quick filter hides the
chosen voice, switch to All voices.  Nothing is enabled or played.

Display and speak Voice Workbench navigation help.

Read one data-only routing profile into the staged workbench copy.

Show logical voices.

Spoken workbench for logical styles and physical voice routing.

In addition to any hooks its parent mode
‘emacsvox-aural-tabulated-mode’ might have run, this mode runs the
hook ‘emacsvox-aural-voice-workbench-mode-hook’, as the final or
penultimate step during initialization.
