# Transcripts

At the core of Castmagic is transcription. Transcription is an async process and can vary in duration based on factors such as audio language, however it is typically complete in around 15 minutes or less.

Transcription supports speaker diarization by default. You will find paragraphs labled by speaker in the `"utterances"` key of a completed transcript response.
