MacOS – Using dictation to transcribe audio files in batch

audiomacossirivoice-dictation

I have lots of audio files that I want transcribed. Dictation is the best transcriber I have found that will run on my MacBook (there exist others like PocketSphinx but this is no where near as accurate).

How can I use Dictation to transcribe audio files in batch?

You can use SFSpeechRecognizer (mirror) (requires macOS 10.15+): this is made for speech recognition and it's an SDK so you can write some code for batch processing.

Perform speech recognition on live or prerecorded audio, receive transcriptions, alternative interpretations, and confidence levels of the results.
