Understanding Machine Learning Services on AWS—From Zero to Hero

Amazon provides an extensive suite of machine-learning services designed to streamline time-consuming processes. AWS Textract, Rekognition, Comprehend, Transcribe, and Polly are some of these important services. These services help automate text extraction and recognition and integrate text-to-speech and speech-to-text services in our applications. 

In this Cloud Lab, you will create an S3 bucket to provide input and then store the results of AWS Textract and Rekognition. After this, you will create an IAM role to provide necessary permissions to other AWS services. You will then create a Lambda function that will be triggered whenever a document is added to the S3 bucket. The lambda function will extract text from the document and analyze it.

In the second part of this Cloud Lab, you will convert text-to-speech using Amazon Polly and save the speech in the S3 bucket. After this, the same audio would be converted to text using Amazon Transcribe. The lab will also help you understand and execute Amazon Comprehend to identify Personally Identifiable Information (PII) from the text. Finally, you will execute Amazon Transcribe, Comprehend, and Polly integrated into a Flask application. 

After completing this Cloud Lab, you will have practical knowledge of five machine learning services offered by Amazon.
