PutLexicon - Amazon Polly


The following code sample show how to use Python (boto3)-based applications to store a pronunciation lexicon in an AWS Region.

For more information on this operation, see the reference for the PutLexicon API.

Note the following:

  • You need to update the code by providing a local lexicon file name and a stored lexicon name.

  • The example assumes you have lexicon files created in a subdirectory called pls. You need to update the path as appropriate.

The following code example uses default credentials stored in the AWS SDK configuration file. For information about creating the configuration file, see Step 3.1: Set Up the AWS Command Line Interface (AWS CLI).

For more information on this operation, see the reference for the PutLexicon API.
