+This pattern facilitates automatic audio transcription by using the Amazon Transcribe service through a serverless event-driven architecture. When audio files are uploaded to S3, they are automatically transcribed using Amazon Transcribe via a Lambda function invoked by S3 events.
 
 This pattern enables speech-to-text transcription use cases by providing a serverless event-based pipeline that can process audio files uploaded to S3. The pattern uses AWS Lambda to coordinate with the Amazon Transcribe service, making it easy to integrate transcription capabilities into your applications without the need to manage infrastructure or manually initiate transcription jobs.
