Why we included this project

Anyone who produces captioned video, whether editors, archivists, or course makers, can script this tool to turn a video or audio file into timed subtitles. It detects speech regions, sends those chunks to the Google Web Speech API for transcription, and writes out an SRT or JSON file, optionally translating the captions to another language when you provide an API key. Because it is a command-line utility with flags for concurrency, source language, and output format, it fits into batch pipelines without needing a GUI. One honest caveat: the project is no longer maintained, so you will likely want to verify it against a modern transcription engine or be ready to adapt the code.
