Vietnamese text to speech
Vietnamese is written in Latin script, which routinely tricks people into assuming it behaves like a European language. It does not. A set of six tones separates words otherwise identical to each other, and the marks carrying those tones stack on top of vowels that may already bear a separate mark modifying which vowel they are.

135/500That stacking is where text handling usually breaks down. One vowel can hold a quality mark and a tone mark simultaneously, and losing either produces a different word rather than a slightly degraded version of the intended one. Text that has passed through careless processing arrives stripped and effectively unreadable.
Because the great majority of words are a single syllable, meaning rests heavily on those distinctions surviving intact from your document through to the audio. Northern and southern speech realise several tones noticeably differently, which is worth weighing when you choose a narrator for a specific audience.

Vietnamese production details
Full tone set reproduced
Tone is handled as lexical information, since it separates words sharing every other sound within the same syllable.
Stacked diacritics preserved
A vowel bearing both a quality mark and a tone mark keeps both, because dropping either yields an entirely different word.
Single-syllable precision
With most words one syllable long, small distinctions carry more weight than in languages spreading redundancy across syllables.
Regional realisation differs
Northern and southern speech render several tones differently, which is worth considering when picking a narrator per market.

Questions, answered
Is the complete tone set actually produced?
Yes. Tone separates words that share every other sound in Vietnamese, so reproducing the full set is a baseline requirement rather than a refinement to be layered on later.
What happens if my text has lost its diacritics?
Quality drops sharply and frequently becomes unusable. Stripped text is genuinely ambiguous, since a single bare syllable can correspond to several unrelated words distinguished only by those marks.
Why do some vowels carry two separate marks?
One identifies which vowel it is, the other carries tone. They perform different jobs, so both have to survive intact from your document into the narration to preserve the intended word.
Is the delivery northern or southern?
The voice you choose determines that. The two regions realise several tones differently, so audition narrators against the specific audience you actually publish to before committing.
Can I paste text copied out of a PDF?
Check the diacritics first. PDF extraction frequently mangles stacked marks, and text that looks acceptable on screen can be missing exactly the information narration depends on.
