transcription

2024 Update: I have a short video outlining my end-to-end process for subtitling all my videos on YouTube using Whisper/MacWhisper:

.embed-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } .embed-container iframe, .embed-container object, .embed-container embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }

Late last year, OpenAI announced Whisper, a new speech-to-text language model that is extremely accurate in translating many spoken languages into text. The whisper repository contains instructions for installation and use.

tl;dr:

You can use the Dictation feature built into your Mac to transcribe audio files, and in my experience, it's been about 98-99% accurate, so it saves a lot of time if you want to index your audio files, or you need a transcript for some other purpose.

These instructions were last updated for macOS Monterey 12.4.

First, open up System Preferences, go to Keyboard, then the 'Dictation' tab:

Turn on Dictation, and when prompted, accept the terms for Apple's Dictation service. Also take note of the 'Shortcut' (e.g. 'press dictation key' or 'press control twice'. You'll use that to activate dictation later.
