Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Setting up the IAM policy for asynchronous synthesis

In order to use the asynchronous synthesis functionality, you will need an IAM policy that allows the following:

  • use of new Amazon Polly operations

  • writing to the output S3 bucket

  • publishing to the status SNS topic [optional]

The following policy grants only the necessary permissions required for asynchronous synthesis and can be attached to the IAM user.
