If PlayHT output sounds off: fix the script before blaming the voice. Add punctuation to force pauses and emphasis, set pronunciation rules for names and jargon, and regenerate weak sections individually instead of the whole track. Test the exact language, accent, and voice style your project needs, a big voice library does not mean every voice is strong in every language.

Context: Web (PlayHT review, playhtai.com): describes the real output-quality problem. Even strong AI voices can misread names, flatten emphasis, or deliver long passages with repetitive rhythm. A polished result takes work: punctuation changes, pronunciation rules, and regenerating individual sections. Voice quality also depends on script formatting and language, not just the voice model.
