DEDUPEDWho it is forA video editor or creator who already has an .srt or .vtt subtitle file for a video and wants a Vietnamese voice track to add in CapCut, Premiere, or a similar editor.
The problemRecording voice-over that matches each subtitle timing by hand is slow, and misaligned narration is hard to fix in the editor.
The outcomeA single WAV or MP3 audio file whose lines sit at the same timestamps as the subtitles, plus an adjusted .srt file if any lines had to shift.
What you need first
- A Windows 10/11 64-bit, Ubuntu/Debian 64-bit, or macOS 13/14 computer, with at least 8 GB RAM and 3 GB free disk space (5 GB recommended)
- The text to read, as a TXT, PDF, or Word (.docx) file, or pasted directly into the app
- For the subtitle step, an .srt or .vtt subtitle file for the video
Steps
- Install CIT Voice Studio from the Releases page at https://github.com/Cuongyd196/cit-voice-studio/releases/latest and open it.
- Open the Đọc file tab and drop your .srt or .vtt file into it. Check the list of lines and timestamps that appears.
- Choose a voice and a reading speed, then click Lồng tiếng.
- Listen to the result, then download the WAV or MP3 file. If the app shows a subtitle file with shifted timestamps, download that too.
- Import the audio into your video editor and place it on the timeline, then use the adjusted .srt for the on-screen text if it was shifted.
Prompt for your agent
Using the CIT Voice Studio app on this computer, dub the subtitle file <path-to-srt-file> into Vietnamese through the Lồng tiếng feature. Expected output: one audio file whose total length matches the video, plus an adjusted .srt if lines were shifted. Verify that the audio length matches the video duration and that no sentence is cut off.
Caveat. The README says sentences that run long are read faster, up to 1.5 times, and may push later sentences back, so very dense subtitles may need a lower speed or shorter wording.
