Text-to-Speech Script Cleaner
Turn numbers, prices, dates, acronyms and symbols into speakable words — so your AI voice reads every line correctly the first time.
Everything runs in your browser — your script is never uploaded. Always give the result a quick read: some text (like product codes) may need a manual tweak.
Why clean your script before text to speech?
AI voices are excellent readers, but they still trip over things that look fine on screen: dates, prices, percentages, acronyms, website addresses and formatting symbols. A mispronounced number means a retake — and every retake costs time and credits. This free tool rewrites those parts of your script into words, exactly as they should be spoken.
What the script cleaner converts
- Numbers: 1,250 → one thousand two hundred fifty; 3.5 → three point five
- Money: $5.99 → five dollars and ninety-nine cents; $2.5M → two point five million dollars
- Percentages, temperatures and units: 50% → fifty percent; 120 km → one hundred twenty kilometers
- Years and decades: 2026 → twenty twenty-six; the 1990s → the nineteen nineties
- Times and ordinals: 3:30 pm → three thirty P M; 21st → twenty-first
- Ranges: 20-30 → twenty to thirty
- Acronyms: API → A P I, while words like NASA stay as words
- Abbreviations: Dr. → Doctor; e.g. → for example; vs. → versus
- Websites and emails: example.com → example dot com
- Formatting: removes Markdown symbols, bullet characters and emojis
