The areas of Amazon Lex that could be improved include context management. I have used Google Dialogflow and Amazon Lex both. Context management is better in Google Dialogflow, but it is something which Amazon Lex can improve. It is a good service and they are keeping up with improvements. It should be noted that generally the people who use Amazon Lex use other services also. I have never found a customer who is using Amazon Lex with a third-party system. They have come to Amazon Lex only when they want to use other services of AWS.
Amazon Lex's utterances could be improved. If a customer does not speak a sentence or word correctly in the utterances, the solution will show an error.
AWS Lex has a complex web integration. It has fewer deployment channels. Lex is not multilingual and supports only English. The preparation of the data set is complicated; the utterances and entities mapping is somewhat critical. To support other multi-language functionality with Amazon Lex, you’ll need to combine the use of other services including Amazon Comprehend and Amazon Translate to support non-English languages. The maximum duration of speech input is 15 seconds. Amazon Lex bots require an internet connection and cannot be accessed locally.

The product can be expensive based on our workloads.
