Link to issue number:

Fixes #12393, follow up of #12251

Summary of the issue:

Using shift to resume speech after using shift to pause speech does not resume speech.

This is because when isPaused is imported through speech\__init__.py it is does not reference the global variable used in speech.py

Description of how this pull request fixes the issue:

Removes the use of top level variables in speech.py in favour of a private dataclass to manage state, and an enum for certain modes. Constants (or rather, variables with names in all capitals) remain as is.

Testing strategy:

Using reproduction steps in #12393 to manually test the pausing and resuming of speech.

System tests for this may be useful, but require a change to the system test spy synth driver.
