Tone Analyzer

The Tone Analyzer service uses linguistic analysis to detect emotional tones (anger, disgust, fear, joy and sadness), social propensities(openness, conscientiousness, extroversion, agreeableness, and emotional range), and language styles(analytical, confident and tentative) in written communication. These five types of emotions it can detect are exactly the same five small monsters(emotions) in the movie Inside Out, such a coincidence!

Where to use the Tone Analyzer

• Chat Bots: Enable an automated agent to detect customer tones and based on the tones detected, craft suitable responses such as "Sorry that you are upset about this problem,” and, “I'm glad you are satisfied with my service."
• Customer Care Monitoring & Quality Assurance: An application based on Tone Analyzer service can monitor the overall tones in agents' communications, detect anomalies, and highlight opportunities to train agents on how to better communicate.
• Personal or Business Communications: The Tone Analyzer service can analyze text in an application add-on. For example, an email widget that you would run on your content like a spell checker.
