Pronunciation and Pacing
Natural synthetic speech depends on how words are pronounced and how pauses shape the sentence.

Fix names, acronyms and unusual terms.
Use punctuation and line breaks intentionally.
Match speed to information density.
Understand the working model
Before generating a long narration, test the difficult words in isolation. Product names, abbreviations, numbers and mixed-language phrases are common failure points.
Pacing should follow meaning. Dense explanations often need shorter sentences and more pauses; emotional narration may use longer phrases and more variation.
Practice
Apply the pattern above to one real task you already do. Keep the first version small enough that you can inspect every input and output.
Do not fix every pacing problem by making the voice slower. Improve the script first.
Test difficult words early and write for the ear, not just for the page.
