Creates the output to be read by TTS.

Note: some languages need to read "one hour" as "a hour" (indefinite article). Also, other languages
use the <tt>quantity="1"</tt> plurals rule for other values than 1, such as Slovenian, so it is not
possible to store the literal value to use for 1 in this rule. For this reason, we need to have one
string for the unit quantity ("one meter") and a plurals rule for everything else.

on unit expressions.
