It already does.

This is already possible. The channel's LANGUAGE code is split, piece by
piece (separated by underscores), and used to build paths to look for
files. The first file found is used.

This means that, for example, LANGUAGE can be set to en_GB_female_BT,
which would search for files in:

.../sounds/en/GB/female/BT
.../sounds/en/GB/female
.../sounds/en/GB
.../sounds/en
.../sounds
