**To detect the parts of speech in an input text**

The following ``detect-syntax`` example analyzes the syntax of the input text and returns the different parts of speech.
The pre-trained model's confidence score is also output for each prediction. ::

    aws comprehend detect-syntax \
        --language-code en \
        --text "It is a beautiful day in Seattle."

Output::
