%% speech transcription, natural language processing, and intelligent search
%% capabilities.
%%
%% It performs sentiment analysis, detects issues, and enables you to
%% automatically
%% categorize contacts.
%%
%% Amazon Connect Contact Lens provides both real-time and post-call
%% analytics of customer-agent
%% conversations. For more information, see Analyze conversations
%% using speech analytics:
