Translators: This phrase is spoken to inform the user that what is about to
be said is part of a mathematical fraction whose bar is not displayed. See
https://en.wikipedia.org/wiki/Combination for an example. Note that the
comma is inserted here to cause a very brief pause in the speech. Otherwise,
in English, the resulting speech sounds like we have a fraction which lacks
the start of the bar. If this is a non-issue for your language, the comma and
the pause which results is not needed. You should be able to test this with
"spd-say <your text here>" in a terminal on a machine where speech-dispatcher
is installed.
