Ah, OK, I understood you that your delimiter is just floating ontop of the
LANG_ IDs. If it's in safe distance, we have the two-table approach.

Not in this way. Currently, the ID is directly used as an offset into the
directory. It is just checked against an upper bound, which is part of the
voice file header. Non-voiced IDs have a zero directory entry. This wastes 8
bytes per such entry, on the other hand saves storing the ID itself, but the
voice file is huge anyway. I'm not searching for an ID. I could either do that,
or split into two tables.

Either way, I agree to your approach of sorting the voice-only IDs into a
way higher range. This will overcome my resistance to introduce a lot more of
them, e.g. for spelling, file types, etc.
