Teaching AI Voices to Pronounce Brand Names Correctly
TLDR:AI voices guess at pronunciation based on spelling. Uncommon brand names, product names, and proper nouns get guessed wrong. The fix is a pronunciation dictionary: a list of terms mapped to phonetic spellings that the engine uses on every generation. Once a term is in the dictionary, it stays fixed across every project, every chapter, every episode.
Frequently Asked Questions
Why does AI voice mispronounce my brand name?
AI voice engines generate pronunciation from spelling rules trained on common words. Brand names and invented terms do not follow common rules, so the engine guesses. The guess is often wrong for any name that looks like a normal word but is pronounced differently (like 'Nike' being pronounced 'nyke-ee' instead of rhyming with 'bike').
How do I fix pronunciation for a specific word in Vois?
Use the pronunciation dictionary. Add the word along with a phonetic spelling that the engine will apply whenever it encounters the term. The dictionary is searchable, scoped by project or global, and persists across sessions. Once you add a term, all future generations use the corrected pronunciation.
Should pronunciations be global or project-specific?
Both, depending on the term. Company names, common product names, and recurring character names should be global so you only fix them once. Project-specific terms (a unique character in one novel, a specific product in one campaign) should be scoped to that project to avoid polluting unrelated work.
How do I write a phonetic spelling the engine will understand?
Use natural phonetic spelling, not IPA. Write what the word sounds like using common English letter patterns. 'Nike' becomes 'nye-kee'. 'Hermes' (the brand) becomes 'air-mez'. Test the pronunciation, adjust if it sounds off, and save when it matches what you expect.
Can I import pronunciation dictionaries from other tools?
Yes. Vois's pronunciation dictionary supports import and export, so you can move terms between projects, share a dictionary across a team, or bring over entries from a prior tool. The format is straightforward (term plus phonetic spelling) and portable.
