Understanding transcription files for Amazon Chime SDK media capture pipelines
The transcription-messages folder contains transcription files in the .txt format. However, the folder only receives files when you enable live transcription. For more information about enabling live transcription, see Using Amazon Chime SDK live transcription.
The folder includes all partial and complete transcription messages, and each message is a JSON object. File names contain the <yyyy-mm-dd-hour-min-seconds-milleseconds> timestamp. You can see transcription file examples at Processing a received Amazon Chime SDK live transcript event.
