Upload of files to S3 and implement AWS Polly

[HugoCL]

Problem/Functionality

The AWS APIs we will use for our app will require that the files have to be uploaded to an S3 bucket.

Solution

Create the backend service that allows the upload of audio files to an S3 bucket. This service has to create the default bucket (if it doesn't exist) and upload all files in that bucket.

Work with the text from the user and conect to AWS Polly to receive the speech from the API.
User input in the Frontend -> Send it to the backend -> Send it to the AWS service -> Receive the S3 link -> Send the link to the frontend-> Let the user hear the audio stored in the S3 bucket
