Make your text TTS-ready with proper punctuation. Missing periods, absent commas, and inconsistent quotation marks all degrade speech quality. This tool fixes punctuation and optionally adds TTS-specific pauses for natural-sounding audio.
What this tool fixes:
- Missing periods at sentence endings
- Missing commas after introductory phrases
- Double/multiple punctuation ("!!" → "!", "..." → "…")
- Inconsistent quotation marks
- Sentences starting with lowercase letters
- Smart/curly quotes → straight quotes
- Double hyphens → em dashes
TTS-specific enhancements:
- Add commas before "but", "however", "therefore", "although"
- Add pauses at paragraph breaks
- Convert abbreviations that confuse TTS (e.g., "e.g." → "for example", "i.e." → "that is")
- Add periods after numbered items for clearer pacing
