New/Update voices

I understand this app is still in production, maybe consider adding new voices possibly integrating SIRI. The voices currently sound like robots and aren’t understandable unless if you want to keep the volume all the way up. This might be a bug also.

The issue names no files, tests, or entry points. Clarify whether the goal is adding new voices, integrating Siri, improving intelligibility, or addressing a volume-related bug. Define the supported platform, expected voice behavior, and tests or other criteria that would show the work is complete.
