**To inspect the syntax and parts of speech of words in multiple input texts**

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

    aws comprehend batch-detect-syntax \
        --text-list "It is a beautiful day." "Can you please pass the salt?" "Please pay the bill before the 31st." \
        --language-code en

Output::
