Using the ListLexicons operation

Amazon Polly provides the ListLexicons API operation that you can use to get the list of pronunciation lexicons in your account in a specific Amazon Region. The following Amazon CLI call lists the lexicons in your account in the us-east-2 region.

aws polly list-lexicons

The following is an example response, showing two lexicons named w3c and tomato. For each lexicon, the response returns metadata such as the language code to which the lexicon applies, the number of lexemes defined in the lexicon, the size in bytes, and so on. The language code describes a language and locale to which the lexemes defined in the lexicon apply.
