TTS Script Cleaner

Why voices misread scripts

Text-to-speech voices are trained to read words, and most do well with ordinary sentences. Symbols and formats are where they slip: a price might be read digit by digit, a date in numbers might be read as a subtraction, and a web address might be read as one long word. Each mistake means another generation and another edit.

What this cleaner changes

• Prices in dollars, euros and pounds, including cents and "k" or "million" amounts.
• Percentages such as 15% → 15 percent.
• ISO dates such as 2026-10-12 → October 12, 2026.
• Phone numbers, read in clear groups of digits.
• Emails and web addresses, with "at", "dot" and "slash".
• Abbreviations: e.g., i.e., etc., vs., 24/7, & and #1.

The complete list is on our how it works page. In the studio these rules run automatically, and you can add your own words, such as brand names, to a pronunciation dictionary.

What it leaves alone

Ambiguous formats like 10/12/2026 are not changed, because they mean different dates in different countries. Names are not changed either; that's what the pronunciation dictionary is for.
