Text to Speech pronounces punctuation?

To whom it may concern: text-to-speech inconsistently pronounces the word "dot" when using the male voice (Mathew). The text formatting is consistent with no extra spaces or special characters. It only happens at the end of the narration and even happens occasionally after the period at the end of the voice over speech has been removed entirely.

I unfortunately cannot provide an example (proprietary content) , but it is taking place in several instances across multiple courses in this way. Each one has to be checked individually after published each time to be certain it is not taking place. Please have developers look into the code logic and provide a practical suggestion as a work around once pin-pointed.

Longer paragraphs can sometimes produce the word "dot" with a pause prior. If I retain the final period back or even remove the final period, it speaks the word "dot" in both cases. When I reduce text from 1,465 characters (with spaces) to 789 characters (with spaces), the same remaining text will not produce the pronounced "dot" audio at the end (with or without a period at the end); so I am inclined to guess it something conditional relating to lengthy text-to-speech content with this particular case and character voice.

It sounds minor, but quickly becomes quite troublesome when producing multiple courses for clients. With these instances, I would work around this by breaking the audio into shorter audio segments and patch them together using the timeline in Storyline; since I am actually exporting to Articulate Studio, which will not easily allow dual audio sources per slide, I will need to manually edit each audio to remove per instance. Thank you in advance for looking into it further.
