Explanation
Each AWS managed AI service solves one kind of problem without the customer training a model: Transcribe (speech to text), Translate (text between languages), Comprehend (insights from text), Lex (conversational bots), Textract (data from documents) and Polly (text to speech). Knowing which input and output each service handles is enough to answer most service-selection questions.
