Corrects/restores the capitalization of text, taking proper nouns into account.
This API corrects the case of text according to the conventions for regular sentences (sentence case). This means that the first word of each sentence is capitalized, as well as all proper nouns. All other words are lowercased. In Natural Language Processing (NLP), this is known as truecasing. Supported languages are English, Dutch, French, German, Indonesian, Italian, Polish, Portuguese, Spanish, Swedish and Turkish.
