 #### Create an environment
 Creates an environment for the service instance. Note: You can create only one environment per service instance. Attempting to create another environment for the same service instance results in an error. See the [Discovery service home page][discovery-sizing] for additional information about sizing and pricing. To create a free trial environment, specify the value of size as 0 (zero).

 ### Usage
 Use [Tone Analyzer][tone-analyzer] to detect three types of tones from written text: emotions, social tendencies, and language style. Emotions identified include things like anger, cheerfulness and sadness. Identified social tendencies include things from the Big Five personality traits used by some psychologists. These include openness, conscientiousness, extraversion, agreeableness, and neuroticism. Identified language styles include things like confident, analytical, and tentative. Input email and other written media into the [Tone Analyzer][tone-analyzer] service, and use the results to determine if your writing comes across with the tone, personality traits, and writing style that you want for your intended audience.
