Repeated dialogue and different pronunciation of name from 1st to 2nd time

# What happened?
In this video, the NPC introduces himself as "Brother E-Sumi-Yan" but pronounces it as "Brother Sumi-Yan". Then, TextToTalk repeats the same line of dialogue but instead it says it like "Brother E-Sumi-Yan" as the expected pronunciation.

# What should happen?
It should have just read the line once and pronounced "Brother E-Sumi-Yan" with the "E-" part included.

# Steps to reproduce
* Enable "Read NPC dialogue from the dialogue window" from the Synthesizer Settings tab.
* Enable "NPC dialogue" in the current active preset in the Channel Settings tab.
* Start a new conjurer character.
* Speak to E-Sumi-Yan at the Conjurer's guild.
* Answer his question with "no" every time so that you can repeat his dialogue until you can reproduce the issue.

# Possible Cause
I suspect that the reason for the repeat is because TextToTalk is getting slightly different text from the dialogue window and from the chat window, so it ends up reading them both. Because TTT correctly pronounces the name the second time, I don't believe that this is a lexicon issue.
