Word Sync

Word-by-word highlighting for TTS voiceovers in ElevenLabs and Cartesia: synced script, romanized view, word cursor on the page.

Word Sync shows which word of your voiceover script is being spoken, as it plays. Built for VO and TTS work in Indian languages and English, on ElevenLabs and Cartesia. On the page • A pointer and underline follow the spoken word right inside the ElevenLabs or Cartesia text box, with the word in English letters above it. Works with the side panel closed. • Option-click (Alt-click) any word in your script to play from that word. • An optional subtitle strip you can drag anywhere. In the side panel • Your takes, word-synced: each word lights up as it's spoken. Click a word to jump, double-click to loop it. • Follows the page live: play Generation 1 or 2 on ElevenLabs and the panel switches to that take. • G1 / G2: switch between the two generations of one click at the same word. • Mine / Everyone: on a shared account, see only the takes made from your Chrome. • Script, Roman or Both: read Hindi, Marathi, Bhojpuri, Gujarati, Bengali, Assamese, Odia, Tamil, Telugu, Kannada and Malayalam scripts in English letters. • English line under each sentence, in all of these languages and most others. • Closest word: type how a word sounds or what it means in English and jump to it. • Export subtitles (SRT), word timings (CSV), Audacity labels or the audio. • Align file: drop any recording, paste its script, and sync it. How timing works Word Sync uses the word timings ElevenLabs or Cartesia already give when they exist (free). Otherwise it transcribes the take with your own ElevenLabs or Cartesia key and lines it up with your script, flagging words said differently. Results are saved, so replays cost nothing. Privacy Your API keys, takes and settings stay in your browser. Word Sync has no server and collects nothing. Audio and script text go only to ElevenLabs or Cartesia, with your own key, when a take is synced. Script text goes to Google Translate only when you turn on English lines or search a word by meaning, and you can switch that to Chrome's on-device translator in Settings. Word Sync is an independent tool and is not affiliated with ElevenLabs or Cartesia.
