SSML Does not work for me
Well, I have discovered the issue with the <sub> tag and likely a few others that I have tried and failed with. The "Help" that Articulate provides on their SSML support page is inadequate. The syntax is not really spelled out. When I see the syntax on the Amazon Polly site, i discover the problem.

<sub>
This tag is supported by generative, long-form, neural, and standard TTS formats.
Use the <sub> tag with the alias attribute to substitute a different word (or pronunciation) for selected text such as an acronym or abbreviation.
This uses the syntax:
<sub alias="new word">abbreviation</sub>
In the following example, the name "Mercury" is substituted for the element's chemical symbol to make the audio content clearer.
<speak>My favorite chemical element is <sub alias="Mercury">Hg</sub>, because it looks so shiny.
</speak>
So, to use the sub tag to spell out CTR instead of having it shortcut to "center" I would need to add something like:
<sub alias="see tee are">CTR</sub>
Obviously, just writing C-T-R is much simpler, as Joe mentioned earlier. At least now I know to check the Polly site for more complete syntax.
