Thank you for reaching out. Unfortunately there is no mechanisms we can propose other than tweaking some code that will track generated traffic and block it if it exceeds a certain accepted limit on the client side.
On the other had you can also request a limit 'decrease' using this page for Amazon Polly using this link: https://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html
Thank you! However, I admit that it is a feature not easy to find in online searches, I have never found any suggestions related to the settings about limits of the the various services. Very useful advice.
