Translators: This phrase is spoken to inform the user that the last spoken
phrase is the end of a mathematical fraction. For instance, given x+1/y+2,
Orca would would say "fraction start, x+1 over y+2, fraction end."

Translators: This phrase is spoken to inform the user that what is about to
be spoken is a square root. For instance, for √9 Orca would say "square root
of 9, root end" (assuming the user settings indicate that root endings should
be spoken). Note that the radicand, which follows the "of", is unknown and
might not even be a simple string; it might be the square root of another
expression such as a fraction.

Translators: This phrase is spoken to inform the user that what is about to
be spoken is a cube root. For instance, for the cube root of 9 Orca would
say "cube root of 9, root end" (assuming the user settings indicate that root
endings should  be spoken). Note that the radicand, which follows the "of",
is unknown and might not even be a simple string; it might be the cube root
of another expression such as a fraction.

Translators: This phrase is spoken to inform the user that what is about to
be spoken is an nth root. https://en.wikipedia.org/wiki/Nth_root. For instance,
for the fourth root of 9, Orca would say "fourth root of 9, root end" (assuming
the user settings indicate that root endings should be spoken). Note that the
index, which precedes this string, is unknown and might not even be a simple
expression like "fourth"; the index might instead be a fraction.

Translators: This phrase is spoken to inform the user that what is about to
be said is part of a mathematical root (square root, cube root, nth root).
It is primarily intended to be spoken when the index of the root is not a
simple expression. For instance, for the fourth root of 9, simply speaking
"fourth root of 9" may be sufficient for the user. But if the index is not
4, but instead the fraction x/4, beginning the phrase with "root start" can
help the user better understand that x/4 is the index of the root.

Translators: This phrase is spoken to inform the user that the last spoken
phrase is the end of a mathematical root (square root, cube root, nth root).
For instance, for the cube root of 9, Orca would say "cube root of 9, root
end" (assuming the user settings indicate that root endings should be spoken).

Translators: This phrase is spoken to inform the user that what is about to
be spoken is subscripted text in a mathematical expression. Note that the
subscript might be simple text or may itself be a mathematical expression,
and in this instance we have no additional context through which a more user-
friendly word or phrase can reliably be chosen.

Translators: This phrase is spoken to inform the user that what is about to
be spoken is superscripted text in a mathematical expression. Note that the
superscript might be simple text or may itself be a mathematical expression,
and in this instance we have no additional context through which a more user-
friendly word or phrase can reliably be chosen.

Translators: This phrase is spoken to inform the user that what is about to
be spoken is subscripted text which precedes the base in a mathematical
expression. See, for instance, the MathML mmultiscripts element:
