Mispronounce the brand once and the whole spot is unusable
The most embarrassing AI voiceover failure isn't the wrong tone — it's getting your product name wrong. nginx read letter by letter, SaaS spelled out, a founder's surname mangled. In a long script those errors repeat dozens of times.
A pronunciation dictionary fixes exactly that: tell the model how a word should be read, and every generation obeys.
Real A/B
The same English line, before and after applying four rules:
Without the dictionary
With the dictionary
Text: Our SaaS runs on nginx. Ship a GIF with VoiceSmiths.
Rules:
SaaS → sass
nginx → engine ex
GIF → jif
VoiceSmiths → Voice Smiths
Writing rules
A dictionary is a written-form → spoken-form replacement table. No phonetic alphabet required — just spell it how you want it said:
| Case | Written | Read as |
| --- | --- | --- |
| Acronym | SaaS | sass |
| Tech term | nginx | engine ex |
| Brand | VoiceSmiths | Voice Smiths |
| Surname | Ng | Eng |
| Ambiguous word | live (adj.) | lyve |
How to use it
- Studio → Pronunciation: name the dictionary, add rules, create
- Back on the voiceover tab, dictionaries appear as chips — tick the ones to apply
- Stack several at once (e.g. "Brand terms" + "People"), applied in order
It matters most for long-form audiobooks: a proper noun appearing a hundred times gets fixed once.
Versus emotion tags
- Emotion tags like
[whispers]control how it's acted - The dictionary controls how it's pronounced
Use both together — they don't conflict, and neither leaks into subtitles.
