I’m sure we have all cringed at how poorly the text-to-speech system works in game (and in general – YouTube videos, I’m looking at you).
However, there are ways of improving it, and done correctly it can actually be quite effective. Please feel free to take a look at my website to see examples of narration that have been optimised. https://iainbakerfreelance.co.uk/
If anyone would like me to help with the text to speech optimisation of their mod please get in touch.
One question, is the text-to-speech software narrating the text that is on screen, or is it referencing a file somewhere? If so, would altering this file alter the text that appears on screen? I ask as optimising text for text-to-speech narration involves manually altering the text into a format that the software is better able to understand. This results in narration that sounds pretty decent, but if someone were to read the text it would look like gobbledygook ;-)
Ideally you would want the on screen text to be referencing one unaltered file, and the narration referencing a separate optimised file - or a pre-recorded MP3 file. You would then have on screen text that is readable and narration that is listenable.
Hope to hear from you soon
