I asked a question about ua(x) just now.
Then I realized I have no idea how to read aloud the symbol.
Usually I read aloud X1 as "X one". Should I read aloud ua(x) as "u a of x"?

I would pronounce this:
f(x)
as f of x.
And I would pronounce this:
ua
as u sub a.
Therefore, I would pronounce your expression as: u sub a of x.
Note: This assumes that ua is a function. If ua was a variable and not a function, then I suppose this could be a multiplication expression instead. In that case, I would say: u sub a times x

Following the link, we find that in the intended context u_a is indeed a function. – Anton Sherwood Sep 20 at 19:41

@AntonS - True, but for the sake of completeness, I figured it would be better to leave an answer for the general case. – J.R.♦ Sep 20 at 19:43

1If only it were easy to upload an audio file...because a non-native pronunciation of "a" and "u" could be very different from the one native speakers understand. – Mari-Lou A Sep 22 at 11:44

"ua(x)".
Here u refers to an object with a dependance to another object a.
When a is an integer, we commonly say that u is a sequence.
More generally, if a is a complex number, we can say that u is a function of a (just like in the idea that u is function of a, I.E. it depends on a ).
So simply, just as you read "f(x)", f of x, i'd say "ua(x)" u of a, because you could also write
ua(x) = u(a)(x)
