AWS Polly is a service that turns text into lifelike speech, allowing developers to create applications that can talk. It is part of the suite of Voice AI APIs offered by Amazon Web Services, designed to enhance user interaction with applications through voice.
When working with AWS Polly, you might encounter the LexiconSizeExceededException
. This error is typically observed when attempting to use a lexicon that is too large for the service to process.
A lexicon in AWS Polly is a file that allows you to customize the pronunciation of words. This is particularly useful for names, technical terms, or any word that Polly might not pronounce correctly by default.
The LexiconSizeExceededException
is thrown when the size of the lexicon exceeds the allowed limit set by AWS Polly. This limit is in place to ensure optimal performance and resource management within the service.
The error code LexiconSizeExceededException
indicates that the lexicon file you are trying to use is too large. AWS Polly has specific size constraints for lexicons, and exceeding these constraints triggers this exception.
To resolve the LexiconSizeExceededException
, you need to reduce the size of your lexicon or split it into smaller, manageable parts.
First, check the size of your lexicon file. AWS Polly has a maximum size limit for lexicons, which is currently set at 64 KB. Ensure your lexicon does not exceed this limit.
If your lexicon is too large, consider splitting it into multiple smaller lexicons. You can manage multiple lexicons within AWS Polly and apply them as needed.
aws polly put-lexicon --name LexiconPart1 --content file://lexicon-part1.pls
aws polly put-lexicon --name LexiconPart2 --content file://lexicon-part2.pls
Review the content of your lexicon for any unnecessary entries or redundancies. Removing these can help reduce the overall size.
