    Hi aparna,

    Thank you for the feedback.

      Amazon Lex—Let you create a chatbot to use as an Interactive Voice Response (IVR).

      Amazon Polly—Provides text-to-speech in all contact flows.

      Amazon Transcribe—Grabs conversation recordings from Amazon S3 and transcribes them to text so you can review them.

      Amazon Comprehend—Takes the transcription of recordings and applies speech analytics machine learning to the call to identify sentiment, keywords, adherence to company policies, and more.

    The correct answer is Lex, because Comprehend only works with Text based input. The question says they are receiving calls – thus voice based input.

    Hope this helps.

    Let us know if you need further assistance. The Tutorials Dojo team is dedicated to helping you pass your AWS exam!

    Regards,

    Kenneth Samonte @ Tutorials Dojo
