The Tone Analyzer Service analyzes text at the document level and the sentence level. Use the document level analysis to get a sense of the overall tone of the document, and use the sentence level analysis to identify specific areas of your content where tones are the strongest.

To understand how to interpret your tone score, see Understand your Tone Score.



> .5 = likely present
> .75 = very likely present



Identify sentences with stronger tones in context or sorted by score. Highlighted sentences indicate the likelihood of a tone present. If more than one tone is present, the stronger one is shown. Click on a sentence to see a breakdown of all tones.


In sentences_tone, each sentence_id receives a raw_score for each tone in a category. Understand how to normalize raw scores or customize thresholds for your use case in the Documentation.
