What happens to every script.
We clean the text first.
Addresses, prices, dates, and abbreviations make every TTS model stumble. We fix them in every language before synthesis, so the model pronounces your script the way you meant it.
- The most common cause of misreads

One wrong name ruins the take.
Mispronounce a brand, a drug, or a name and the whole line is unusable. It's the first thing generic TTS gets wrong. Our 4M word dictionary teaches how to say the hard words right, in any language.
- Brand and product names
- Complex medical and drug terms
- Hard names, in any language
Every line, validated.
Every line comes back scored: naturalness, word accuracy, clarity, pronunciation. Miss the bar and it fixes automatically, in any language. You set the bar. We hold it.
- Four scores on every line
- Failed lines retry themselves
- One bar across every language
