Before using downloaded offline voices away from Wi-Fi, download the real file, any optional voice or dictionary, and then test the whole flow in airplane mode.
Do the test before you leave.
Travel checklist
Prepare these items.
- Book or document downloaded locally.
- Optional voice installed.
- Current reading position saved.
- Charger or enough battery for the trip.

Test opening and search
Open the file in airplane mode and search for a word if search matters to you.
Test audio separately

Keep one simple fallback
A normal Android system voice or a plain local copy of the file can be useful if heavier options fail.
