Command-line voiceovers for automated pipelines

A dependable voice companion

Revoicer focuses on steady, reliable narration—no flash, just clear delivery with the right tone for product demos, explainers, and internal training.

Fits right into scripted production

Every tool ships as a single executable, making it easy to automate voice updates across courses, lectures, and training libraries. A typical lecture refresh looks like this:

1. Transcribe the original talk. Run transcribe on the lecture recording to generate an editable subtitle file.
2. Polish the script. Use transcript2vtt to turn the transcript into WebVTT, tweak the copy in your editor, and commit it alongside your slides.
3. Regenerate narration. Invoke voicer in your CI job to synthesize clean audio that matches the timing in the VTT file.
4. Distribute automatically. Optionally pipe the output through audiosplit to create per-slide clips before pushing the files to your LMS or video editor.

Everything runs headlessly, so you can schedule updates or trigger them from pull requests without manual studio time.
