S3 Object Lambda allows automatic transformation of files as they are uploaded to an S3 bucket.
A project has been developed using S3 event notification, Lambda function, and AWS Transcribe to transcribe audio and video files uploaded to an S3 bucket.
The architecture involves uploading the video, triggering the transcription process using Amazon Transcribe, and saving the transcript as a JSON file.
A demo and the code for the Lambda function are available for reference.
