How to Improve AI Narration Pronunciation

Pronunciation is the first thing listeners notice. A voice can sound warm and natural and still lose trust by mispronouncing a product name. The good news: most problems come from a handful of causes, and each has a simple fix.

Start with the right voice for the language

Not every voice speaks every language equally well. Before offering a voice for a language, we generate test scripts and transcribe the audio back to text to see how many words come through correctly. In our October 2026 tests, the expressive voices on our standard plans were clear in Hindi (about 93% of words transcribed correctly), but got roughly one in four Telugu words wrong — so we don't offer them for Telugu. Telugu uses our premium voices instead, which transcribed almost word for word.

Your own text is the best test. Pick the language first in the studio — only voices offered for it are shown — then use “Preview First Line” on a sentence with your hardest words.

Fix names and acronyms with respellings

• Acronyms read as a word when you want letters: respell “MCV” as “M C V”.
• Brand or person names: respell phonetically, e.g. “Nguyen” as “Win”.
• Indian-language names in an English script: write them the way an English reader would sound them out, or switch that line to the language's own script.
• Add each rule once under Voice Style & Emotion → Add pronunciations. Rules apply only to the audio; your script isn't changed.

Write Indian languages in their own script

Devanagari for Hindi and Telugu script for Telugu give the voice the clearest signal. Romanised text (“namaste, aap kaise hain”) is ambiguous because there's no single spelling, and voices guess differently. English product names inside a Hindi or Telugu sentence can stay in English letters — they're usually read naturally.

Numbers and units

Write numbers in the form you'd say: “12 लाख” rather than “1,200,000” for a Hindi audience, “twenty twenty-six” only if you want it read that way. Units and symbols (“km”, “%”, “₹”) are generally fine, but check them in a preview.

When a word still sounds wrong

1. Try a different spelling in the respelling rule — split syllables with spaces or hyphens.
2. Rephrase the sentence so the word isn't at a stressed position.
3. Try another voice: pronunciation differs between voices.
4. For expressive voices, a speaking style such as Professional narration can make delivery more careful and evenly paced.

No AI voice is perfect on every word, and we don't claim a pronunciation accuracy figure for your scripts — results depend on the text. Preview, fix the few words that need it, and save the rules so you only fix them once.
