常見使用情境

機器翻譯純文字已經很成熟,難處在於字幕的格式:SRT 和 VTT 有固定的段落結構、序號和精確到毫秒的時間戳,翻譯後必須原樣保留。直接貼到翻譯網站,格式往往會被打亂。

本工具把檔案拆成只含文字的片段,依序逐段翻譯,再用原本的時間戳重新組回 SRT——時間軸與影片完全同步,只有字幕文字改變。做字幕組翻譯、YouTube 多語言上傳、無障礙字幕時,能省下大量手動對軸的時間。

使用技巧

英文譯成西班牙文、法文、德文、葡萄牙文等歐洲語言品質很高;譯成中文、日文、韓文也不錯,但俚語和慣用語最好人工檢查一遍。醫學、法律等專業內容,機器翻譯適合當初稿,發布前請專業人士審校。

人名、品牌名、專業術語很重要時,發布前在譯文裡批次尋找取代一遍。保留原始 SRT——發現問題時對照原文修改最快。VTT 檔會被自動辨識並轉成標準 SRT,SRT 不支援的位置、對齊等 VTT 設定會被移除。

常見問題

這個字幕翻譯工具真的免費嗎?

我的字幕檔會上傳到伺服器嗎?

檔案在你的瀏覽器裡讀取,只有字幕文字會傳送給翻譯服務,不會被保存,工具也不記錄內容。

SRT(.srt)和 WebVTT(.vtt),也可以直接貼上字幕文字。

支援哪些語言?

透過 Google 翻譯支援 100 多種語言,包括中文、日文、韓文、西班牙文、法文、德文、阿拉伯文、印地文等。

翻譯需要多久?

500 段以內的字幕檔大多 30 秒內完成,更長的檔案可能需要一兩分鐘。
