Polly rate exceeded.

If you're receiving a "Polly rate exceeded" error, it means that you've reached the maximum number of requests allowed for the Amazon Polly service within a specific time frame. This rate limit is in place to ensure fair usage of the service and to prevent abuse.

Here are some steps you can take to address the "Polly rate exceeded" error:

1. Check Request Rate:
   • Review your application or system to ensure that it's not sending an unusually high number of requests to the Polly service. Consider implementing rate limiting or request throttling in your application to stay within the allowed limits.
2. Implement Exponential Backoff:
   • If possible, implement exponential backoff in your application. This means that if you receive a rate-limited response, your application should wait a progressively longer amount of time before retrying.
3. Check for Concurrent Requests:
   • Ensure that your application is not making too many concurrent requests to the Polly service. Consider reducing the number of simultaneous requests.
4. Review Your Use Case:
   • Evaluate whether your use case aligns with Polly's intended purpose. If you're using Polly for a high-throughput application, consider whether it's the most appropriate service for your needs.
5. Cache Responses:
   • If your application is making repetitive requests for the same text, consider implementing caching to reduce the number of requests to Polly.
6. Review Polly Pricing:
   • Ensure that you're aware of the pricing structure for Polly. If you're using the service extensively, you may need to adjust your AWS billing arrangements.
7. Contact AWS Support:
   • If you've taken the above steps and are still experiencing rate limits, consider reaching out to AWS Support for further assistance. They can provide specific guidance and may be able to adjust your limits based on your use case.
8. Consider Service Quotas:
   • AWS may allow you to request a quota increase for your account. You can check your current quota limits in the AWS Service Quotas page and request an increase if necessary.

Remember that it's important to use AWS services responsibly and efficiently. Be mindful of the impact of your applications on the AWS infrastructure and other users of the service.
