Subsync

Synchronize your subtitles using machine learning

Subsync analyses and processes the sound from your media files and uses machine learning to detect speech. Speech detection is used to shift existing subtitles for a perfect match in audio and text!

Features

• Machine learning model for voice activity detection (not recognition)
• Shift subtitle as a whole for best match
• Sync every sentence in the subtitle individually
• Sync using existing matched subtitle in a different laguage

Dependencies

• ffmpeg (https://www.ffmpeg.org/download.html)

Installation

pip install subsync
