Summary

In this chapter, we learned about a few of the AWS AI services that can be used to solve various problems. We used the Amazon Rekognition service, which detects objects and faces (including celebrity faces), and can also extract text from images. For text to speech, we used Amazon Polly, while for speech to text, we used Amazon Transcribe. Toward the end of this chapter, we built a chatbot in Amazon Lex.

For language detection and translation in an image, we used Amazon Rekognition, Amazon Comprehend, and Amazon Translate. We learned how to combine all of them into one Lambda function to solve our problem.

For the certification exam, you don't need to remember all the APIs we used in this chapter. There may be questions on a few of the best practices that we learned or on the names of services that solve a specific problem. It is always good to practice using these AWS AI services as it will enhance your architecting skills.

In the next chapter, we will learn...
