aws-solutions-constructs.aws-lambda-transcribe

Create a voice-to-text transcription service using the 'aws-solutions-constructs.aws-lambda-transcribe' package. Your application will allow users to upload audio files to an S3 bucket, which triggers a Lambda function to transcribe the audio using Amazon Transcribe. The transcribed text should then be saved back into another S3 bucket for retrieval. Here are the steps and features you should include in your project:

1. **Setup**: Initialize your project with AWS CDK, ensuring you have the necessary permissions and configurations set up for S3 and Lambda.
2. **User Interface**: Develop a simple web interface where users can upload their audio files directly from their browsers.
3. **S3 Bucket Configuration**: Create two S3 buckets: one for storing uploaded audio files and another for storing the transcribed text files.
4. **Lambda Function Integration**: Use the 'aws-solutions-constructs.aws-lambda-transcribe' package to define the interaction between the Lambda function and Amazon Transcribe. Ensure the Lambda function is triggered upon new file uploads to the first S3 bucket.
5. **Transcription Process**: Configure the Lambda function to invoke Amazon Transcribe to convert the uploaded audio files into text.
6. **Text Storage**: After transcription, save the output text files into the second S3 bucket.
7. **Retrieval Mechanism**: Implement a feature within the web interface that allows users to download the transcribed text files from the second S3 bucket.
8. **Optional Enhancements**: Consider adding features such as real-time progress updates, error handling for failed transcriptions, and user authentication for secure access.

This project aims to demonstrate the seamless integration of AWS services and the power of serverless architectures in building robust applications.
