Audio converter - transcription and document converter

This application automatically transcribes uploaded MP3 audio files, and extracts the transcript to txt/pdf/doc files.

Requirements

• AWS CLI already configured with Administrator permission
• NodeJS 14.x installed

Installation Instructions

1. Clone the repo git clone https://github.com/julianbonilla/s3-lambda-transcribe.

2. From the command line, change directory to repo, then run:

sam build
sam deploy --guided

Follow the prompts in the deploy process to set the stack name, AWS Region and other parameters.

Parameter Details

• AudioBucketName: unique name of an S3 bucket for mp3 uploads (.mp3)
• TranscribeBucketName: unique name of S3 bucket for transcription result (.json)
• ConvertBucketName: unique name of S3 bucket for converted transcript (.txt, .pdf, .doc)
• DefaultLanguageCode: The language code of your audio file (en-US)

How it works

• Upload an MP3 file of a person speaking (ending in the suffix '.mp3') to the target S3 bucket.
• After a few seconds you will see a transcription file in the TranscribeBucketName (using the same object name with .json appended).
• This triggers a conversion from .json to .txt/pdf/doc and the result is stored in the ConvertBucketName.
