To detect the dominant language of input text
The following
detect-dominant-language
analyzes the input text and identifies the dominant language. The pre-trained model's confidence score is also output.aws comprehend detect-dominant-language \ --text
"It is a beautiful day in Seattle."
Output:
{ "Languages": [ { "LanguageCode": "en", "Score": 0.9877256155014038 } ] }
