What is Watson Tone Analyzer?

The IBM Watson® Tone Analyzer uses linguistic analysis to detect emotional and language tones in written text. 

Watson Tone Analyzer can analyze tone at both the document and sentence levels. You can use the service to understand how your written communications are perceived and then to improve the tone of your communications. Businesses can use the service to learn the tone of their customers' communications and to respond to each customer appropriately, or to understand and improve their customer conversations.
